Description

The First Accurate General Map of Southern Ontario -- Annotated by an Anonymous Canada Company Administrator

Rare separate map of Upper Canada, including a large part of the Great Lakes and New York State, depicting the earliest progress and development of the Canada Company. The map includes hand drawn annotations laying out a road system from Guelph, the Headquarters of the Canada Company, to its lands to the west and the major ports on Lake Ontario which would have serviced the Canada Company Lands. The annotations were likely added about 1827.

The map would appear to be the earliest printed map of Southern Ontario to incorporate the work of James G. Chewett for the Surveyor General of Upper Canada and appears to have been issued prior to the formation of the Canada Company, on the eve of this important period of Canadian growth and expansion. The extensive annotations in what appears to be a contemporary hand strongly suggests use by an important early settler or, more likely a high official in the Canada Company.

Among the most important features of the annotations are two roads showing the route to Guelph, headquarters of the Canada Company These include (1) the road from the town of Galt to Guelph and (2) the road from Guelph to Dundas (the Aboukir Road) which have also been added to the map by an early hand.  The road to Galt corresponds to the 1826 visit of John Galt, founder and Governor of the Canada Company, during which time the topic of "a road from Galt to the lands of the Company in the neighborhood of the now royal City of Guelph, but which had remained a terra incognita up to this time," was discussed (Young).  The Aboukir Road was started the following year, when it was determined that a more direct road through the Clergy Reserve (Puslinch) was required.

The foregoing conclusion does not alter the history of the map's maker, James Chewett.  However, it points to Chewett's having published this Maverick edition of the map prior to the London edition, a fact which was apparently either unknown to scholars or perhaps forgotten since the map was described by Georges-Barthélemi Faribault in a cartobibliography of early maps of Ontario written in 1837.  In her treatise on the Mapping of Upper Canada, Joan Winearls identified the map as #69, reach any conclusions, although she noted that the map was advertised as being in preparation in the Upper Canada Gazette, June 23, 1823 to November, 1824.

Overview

This remarkable map, published in New York by Samuel Maverick, would appear to be the first printed map to contain the cartographic information which later be re-issued in London as Chewett & Ridout's 1825 map of the Province of Upper Canada, engraved by Charles Smith & Son.  Both the Maverick map, printed in New York and the Smith Map, printed in London, survive in 2 states, although the Maverick map is largely unknown and unstudied. 

The present example is apparently the second state of the Maverick map (Maverick 2), significantly revised and updated from the first state (Maverick 1), which survives in a single example at the Leventhal Center in Boston. https://collections.leventhalmap.org/search/commonwealth:4m90fh41w

Historically, Chewett & Ridout's A Map of the Province of Upper Canada and the Adjacent Territories in North America (Smith 1), has been described as the first accurate general map of what is now Southern Ontario.  The map was published in London especially for the use of the Canada Company, then the most important land speculation syndicate in British North America.  However, an examination of the Smith and Maverick maps seems to make it clear that the preparation of the Maverick map pre-dates the Smith map. 

The main feature which points strongly toward this conclusion, the omission of the Canada Company in the title of the Maverick map and at least one change in the notations of land ownership..  The title of the Maverick map reads in full:

Map of the Province of Upper Canada shewing the organized part thereof and the adjacent Country Compiled by James G. Chewett Assistant Draughtsman Under the direction of Thomas Ridout Surveyor General Dedicated by permission to His Excellency Sir Peregrine Maitland K.C.B. &c. &c., &c. Lieutenant Governor During whose administration a very large portion of the Territory has been Organized By his obliged and most obedient Humble Servant Tho. Ridout Survr. Genl.    

By contrast, the title to the Smith map reads:

A Map of the Province of Upper Canada and the Adjacent Territories in North America Compiled by James G. Chewett Assistant Draughtsman Under the direction of Thomas Ridout Surveyor General of the Province Shewing the Districts, Counties and Townships in which are situated the Lands purchased from the Crown by The Canada Company. Incorporated 1825. [changed to 1826 in Smith 2]

The other major difference between the maps is the treatment of the Madawasca River, the primary watercourse connecting the the lands of the Canada Company to th Ottawa River to the west of the future location of Ottawa.  Maverick 1 provides a poorly delineated and incomplete depiction of the River.  Maverick 2 completes the route to Balsam Lake (east of Lake Simcoe), referring to the course as including "numerous falls, Rapids & Portages."

Other differences of note between the maps include:

  • Smith 1 does not incorporate the Bayfield Surveys of the coast of Lake Huron, which only appear in Smith 2.  Maverick 1 and Maverick 2 do not include the Bayfield Surveys.  
  • Smith 1 and Maverick 1 identify the Crown Reserve For The Six Nations Lands in Gore, north of Dumfries.  Smith 2 renames the Crown Lands as "Company Land."  As such, it would seem that the Chewett & Ridout map was produced after the Chewett map.
  • Only Maverick 2 outlines the locations of the 21 Townships of the Canada Company.  Maverick 1 and Smith 1 leave the area blank, whereas Smith 2 calls the area "The Company Territory to be selected in these districts."
  • Maverick 2 refers to the land to the north of the Canada Company Lands as "Indian Territory". Smith 1 and 2 and Maverick 1 do not include this name.
  • Only Maverick 2 shows the Aboukir Road, from Guelph to Dundas and Burlington Bay.
  • Only Maverick 2 shows the Huron Road, built in 1827 by Dr. William "Tiger" Dunlop of the Canada Company from Goderich to Guelph.
  • Both Maverick maps and Smith 2 reference Hen & Chickens (harbor).  Smith 1 fails to include Hen & Chickens.

Differences Between The First and Second States of the Maverick Map

The comparison of Maverick 1 and Maverick 2 has been done by examining the copy at the Leventhal Center (see above link).  Both the Leventhal copy and the present examaple are extensively annotated.  The upper right quadrant of the Leventhal copy is heavily annotated north of the Grand or Ottawa River and the St. Lawrence River, with an inset map of the St. Lawrence extending to Quebec added in the upper right corner.

The following differences are noted between the two maps:

  • Maverick 2 adds at the end of its title:  With the latest Surveys and additions in the Surveyor General's Office,"
  • The Ottawa River is extended approximately 100 northwest to the Pembroke area on Maverick 2.
  • On Maverick 2, the Madawasca River is significantly revised, with a note referencing "Numerous Falls Rapids & Portages," suggesting a water course from the area near the future loation of Ottawa to the area east of Lake Simcoe.
  • On Maverick 2, A number of Rivers east of Lake Simcoe have been removed, notably in Emily, Eldon, Fennelon and Ops Townships (perhaps by abrasion)j
  • The northern extension of the Hurontario Road is added in Maverick 2.
  • Java Township is removed south of Hen & Chickens and Merlin Township is replaced by Nottawasaga at the southeastern corner of Lake Huron
  • Guelph and Puslinch townships are added and numbered 1 and 2, to the southeast of the "Clergy Reserve for the Six Nations Lands."   These two regions had previously been called "Crown Reservation for the Six Nations Lands (1) and Clergy Reservation for the County Lincoln (2).  These names seem to have been scratched off the present map and replaced as noted above.
  • The town of Galt is added above Dumfries (previously named Shade Mills, which did not appear on the map, the town name was changed to Galt in 1825)
  • Above London and east of the St. Cloud River, the Canada Company lands on Lake Huron are added, with 21 new townships and place names, with St. Clair Township changed to Sarina (Sarnia).
  • The Huron Road is added, connecting Grand River with Lake Huron
  • The southern coast of Lake Huron is revised.

Second State Manuscript Annotations

Maverick 2 includes red-line annotations and place name additions between the Great Lakes, suggesting use by some trading in the region at the time of the publication of the map.  The focus of the red-lining seems to be the routes between the larger coastal towns in the region, including:

  • York (Toronto) and Garrison (just east of Toronto)
  • Hamilton (west end of Lake Ontario)
  • Colborne (on Lake Ontario)
  • Point Edward  and "Sarina" (Sarnia, at the south end of Lake Huron)

The annotations appear strongly related to the work of the Canada Company. The most notable addition is the name Guelph (town and township) and the name Puslinch as townships numbered 1 and 2, to the southeast of the "Clergy Reserve for the Six Nations Lands."   These two regions had previously been called "Crown Reservation for the Six Nations Lands (1) and Clergy Reservation for the County Lincoln (2).  These names seem to have been scratched off the present map and replaced as noted above.

James Chewett & the Early Mapping of Upper Canada

The principal author of the map was William Chewett (1753-1849) and his son James G. Chewett.  William was certainly the most consequential surveyor and mapmaker in the early history of Upper Canada. Born in London, England, he arrived in Quebec in 1771, and soon found work as both a military and civilian surveyor in the employ of the British colonial regime. Following the American Revolution, he benefitted greatly from the training he received from Samuel Holland, the Surveyor General of British North America, one of the 18th Century's most important cartographers, who had at one time given surveying lessons to the future explorer James Cook.

In 1792, Chewett moved to the newly-formed Province of Upper Canada (Ontario), where he worked as surveyor for Lieutenant-Governor John Graves Simcoe, under the direction of David William Smyth, laying out new towns and cadastral lots for incoming Loyalist settlers. While Chewett was a highly competent and hard-working professional whose work was invariably of a high caliber, he appears to have been an inept political operator. He was repeatedly unable to navigate the power structure of Upper Canada, which was controlled by a Tory oligarchy popularly known as the "Family Compact". While perennially the most qualified candidate, and frequently serving as the acting surveyor general of the province, he was repeatedly passed over for the top job. A frustrated Chewett expressed early on that political leaders' promises to procure preferment "ended in a mouthful of moonshine" ( DCB). Nevertheless, he was, more than any other individual responsible for shaping the accurate geographic conception of what is now southern Ontario.

In the late 1790s, many of Chewett's cadastral and regional surveys of Upper Canada were used by William David Smyth, the province's surveyor general, to produce A Map of the Province of Upper Canada, describing all the new settlements, townships &c. (London: William Faden, 1800). While not explicitly given any credit for the map, James Chewett was likely its principal author. This map was used as the 'blueprint' for settlement in the province and was the base map on which the cartography of Upper Canada was predicated for the next generation. This so-called "Smyth Series" ran into 13 editions and had the longest publishing history of any map of what is now Ontario.

During this early period, settlement in Upper Canada only hugged the main waterways along the American border, including the shores of Lakes Erie and Ontario, and the Detroit, Niagara, St. Lawrence and Ottawa Rivers. The contemporary mapping of this strip of civilization was impressive, based on triangulated surveys, done to advanced scientific standards. Critically, however, the maps had a glaring flaw. The areas beyond the settled zone, such as the shores of Lake Huron and Lake Nipissing were very poorly mapped, and much of the hinterland was left as a complete void. This created a rather jarring visual juxtaposition to the highly developed aspects of the map, lending the overall appearance of an unfinished composition.

On the eve of the War of 1812 (1812-5), William Chewett prepared an updated version of the Smyth map, which bore his own name as the author, published as A Map of the Located Districts in the Province of Upper Canada (London: William Faden, 1813). While this included the advances in settlement and road construction in the province, the areas north of the southern rim of settlement were still largely unmapped.

James Grant Chewett (1793-1862) followed several professions. Like his father, he was a surveyor, working in the surveyor-general’s department for 30 years, and eventually becoming deputy surveyor-general on his father’s retirement, and also a commander of the 3rd West York Militia. An architect, he designed the first Chewett building (completed by John Howard in 1835), Upper Canada College, which opened in 1829, and the 1832 parliament buildings. Over the years, he served as a director of the Bank of Upper Canada, president of the Bank of Toronto, and chairman of the Canada Permanent Building and Savings Society (later, the Canada Mortgage Corporation). He was also an incorporator of Toronto’s first insurance company, British-America Fire and Life Assurance. 

The Next Generation of the Mapping of Upper Canada: The War of 1812 and the Canada Company

Chewett's maps (Maverick & Smith, referred to in this section simply as Chewett's map) appeared at a critical time in the history of the province that would later become Ontario, following the War of 1812, and at the beginning of a period of explosive economic and population growth.  Chewett's map was a critical primary document at the center of events, so giving rise to its historical importance.

The War of 1812 was a transformative event in the history of Upper Canada. Against the odds, the province's small defense forces of British regulars, citizen militia and their Native Canadian allies fended off repeated attacks by often much larger American armies. While the Upper Canadians' victory was a source of pride and lent a sense of social purpose to the colony (as well as securing Canada's future independence from the United States), the war had wrought extensive damage to farms, towns and property. Notably, the capital York (Toronto) had been sacked and burned in 1813. The British government technically assumed responsibility for compensating subjects for their war losses. However, as the provincial archives, including the records and maps of the Surveyor General's office, went up in flames during the burning of York, much of the information relevant to assessing compensation claims needed to be painstaking reacquired. Many cadastral surveys had to be redone, and visible damage to properties needed to be recorded. Chewett was given the primary responsibility for this important, yet thankless, endeavor.

During this time, another key factor was at play. Up to the War of 1812, a majority of Upper Canadians had been born in the Unite States. While many were United Empire Loyalists, political refugees whose allegiance to the British Crown was beyond reproach, many others, the so-called 'Late Loyalists', were suspected of moving to the province in search of cheap land, and not due to political conviction. During the war, the province's deeply conservative governing elite worried that the recent American immigrants would side with the American invaders. While events showed that these concerns were unfounded, and indeed almost all of the immigrants deeply resented the American invasion, the grandees in York still maintained their suspicions. They believed that henceforth efforts should be made to ensure that the majority of new settlers would come from Britain, and not the United States.

As time wore on, the cash-strapped Crown balked at paying the ever-rising war compensation claims, and so desired to find a new source of revenue for settling these obligations. Moreover, just as had happened in the neighboring American states, people realized that vast fortunes could be made in land speculation.

John Galt (1779-1839), a brilliant, charismatic, and some would say roguish Scottish novelist sensed an opportunity. In 1824, he proposed that a private land development company be formed to settle much of the hinterland of Southern Upper Canada. The company could buy large tracts of undeveloped land from the Crown, the proceeds of which could be used to settle the war compensation claims. In turn, the company could sell the land to migrants, in theory at great profit. Galt petitioned various political figures in London and York, and on July 27, 1825, the Canada Company was given a royal charter by Act of Parliament.

The Company agreed to purchase 400,000 acres of land from the Crown for a sum of 3 shillings, six pence an acre, plus some additional fees. The 'Canada Company Lands' consisted of much of the northern part of Southwestern Ontario, including much of the future counties of Lambton, Huron, Bruce, Wellington and Dufferin. Galt was made the secretary of the Company, and while he officially reported to its board of directors, he was, for all practical purposes, the Company's C.E.O., with complete control over the enterprise's operations.

While the Canada Company was technically a private venture the Crown's stake in the scheme ensured that official resources and manpower were drafted to support the venture. Moreover, various key members of the "Family Compact" were given a financial stake including politicians, business figures and leading Anglican clerics. James Chewett, William's son, was given the task of preparing a grand 'master map' of Southern Upper Canada that would give an accurate and up-to-date depiction of the province and the Canada Company Lands in particular. The completion of the map was seen as an urgent imperative, as many of the Company's investors had only a vague idea of the nature of the Company's territory. Chewett was thus under pressure from the grandees of the province to act fast. While much of the depiction of the province could be pieced together from Chewett's own recent surveys and those of others in the surveyor general's archives, a big problem was that the Canada Company Lands remained the most poorly mapped area of the region.

Fortunately, by coincidence, in the wake of the War of 1812, the British Navy had arranged for all of Canadian coastlines of the Great Lakes be surveyed to advanced scientific standards. While this process was still far from complete, from 1819 to 1824, Lieutenant Henry Bayfield had charted the shores of Lake Huron, from the mouth of the St. Clair River, all the way north and over to the mouth of Severn River in Georgian Bay. This precisely accorded to the shorelines of the Company's lands on Lake Huron. Chewett was able to acquire copies of Bayfield's manuscripts, and combined with accurate surveyed inland areas to the south, these hydrographic surveys allowed him to form an accurate delineation of the limits of the Company Lands.

By the end of 1825, Chewett rushed out an unfinished proof state of what would become Smith 1, which was printed in London. Notably, it did not yet include the critical information supplied by Bayfield's surveys and lacked the adornment of the Company's Coast of Arms (which were still in preparation), as well as numerous detail with respect to settlement and roads.

Given a few more months, Chewett was able to complete the manuscript for the present masterpiece (Smith 2), which became the basis for the first accurate general map of what would become Southern Ontario. As seen on the present marquis example, the depiction of the settled areas of the province is exceedingly precise and detailed, including the placement of towns, townships, counties, rivers, roads, with jurisdictions bodies of water outlined in fine original hand color. Many new towns and settlements have been added, including London, Middlesex County (which would officially be incorporated as a town in 1826) and the newly-settled areas in Simcoe County. The lands controlled by the Canada Company are labeled as "The Company Territory", and while for the most part are unsurveyed, the perimeters of the lands are well defined. Bayfield is specifically given credit for his contribution to Smith 2, as an inscription located off of the shores of Lake Huron reads "This coast was surveyed by Lieut. Bayfield under the orders of the Lords of the Admiralty from 1819 to 1824". The elaborately engraved title is followed by a list of the Canada Company's principals, while its elegant arms adorn the space in the upper center. Importantly, the Company was also able to acquire lots within already established townships in other parts of the province. Those townships that include Company lots are marked on the map with an 'x'. Chewett is explicitly given credit for compiling the map, which is also attributed to Thomas Ridout (1754-1829), the Surveyor General of Upper Canada, who in actuality contributed comparatively little to its preparation.

Chewett's map remained the best map of the region, and the source map for many other cartographers, for many decades. It also served as the blueprint for the Canada Company's operations in the years to come. Winearls describes Chewett's map as:

"Undoubtedly one of the most important maps to be published in the first half of the century -- because of its accuracy and for its impact on other map makers -- was the Canada Company map of 1825-6. The first state of 1825 was unfinished, probably because the company was delayed in receiving its charter, and the 1826 state, the finished map, adds information from the hydrographic charting of the Lake Huron coast by Henry Bayfield to produce the most accurate map of the province until the late 1850s" (Winearls, p. xxii).

The years following the Company's establishment marked a period of explosive growth in Upper Canada, as the province's population grew from 165,000 in 1826 to 375,000 in 1846. The Company experienced considerable success in attracting settlers and developing its territories. New roads were quickly laid across the lands and new towns, such as Guelph (the Company's Headquarters) and Goderich were established (both in 1827).

However, the Canada Company quickly ran into financial and legal problems. This was, in good part, due to Galt's chaotic mismanagement and the web of corruption into which the venture became intertwined. Amazingly, Galt who had almost complete autonomy over the Company's day-to-day operations, did not even keep ledger books. Agreements were often made (and then rescinded) by means of oral conversations, and no proper records were kept. Company agents habitually embezzled funds and leading members of the "Family Compact" accepted bribes and other ill-gotten gains. Many of the regular prospective settlers and investors who had paid money to the Company were defrauded. Upper Canada's courts were inundated with lawsuits against the Company, and public outrage over the Company's behavior is thought to have been a contributing cause to Upper Canada Rebellion of 1837.

The situation was so serious that the Crown was not being paid its fees and quitrents. In 1829, the province's Lieutenant-Governor, Sir Peregrine Maitland, ensured that Galt was dismissed, and had the Company placed under official audit. While the Company continued to play a key role in the settlement of what would become Ontario, the vast riches imagined by the Company's founders remained elusive. The Company existed in various forms until it was folded in 1958.

Chewett's map is one of the most important single maps in not only the history of Ontario, but of Canada generally. As the first accurate general map of Southern Upper Canada, it represents a vital primary artifact charting a critical period in the province's development.

Both the 1825 proof state (Smith 1) and the official version of Chewett's map (Smith 2), pubished in London in 1826, is very rare and was evidently issued in very limited quantities. Such a large and well engraved map would have been quite expensive during its time and would have been issued expressly to be presented to major Company investors or purchased by affluent speculators.  The Maverick maps appear to be even rarer,  with only 1 surviving example of Maverick 1 (Leventhal) and 1 surviving example of Maverick 2 (Toronto Public Library) recorded.

The Road From Guelph to Dundas (hand drawn on Maverick 2) and The Two Townships

Two of the most important manuscript additions on the map are the designation of Guelph and Puslinch and Townships #1 and #2 and the inclusion of a road between Guelph and Dundas, at western end of Burlington Bay and Lake Ontario. This marks the location of one of the most important roads in the early history of the Canada Company.

Puslinch, was originally land set aside for the Clergy Reserve. By law one seventh of all lands surveyed in Upper Canada were set aside for the support of the Protestant clergy. To satisfy the clergy reserve requirement, when the Canada Company secured the Guelph and Huron tract of about one million acres, an equal amount in other places was set aside as Clergy Reserve, including Puslinch, Peel, Maryboro and Wellesley Townships.

Shortly after the settlement of Guelph it became obvious that there must be a more direct route to Dundas through the Clergy Reserve of Puslinch Township was required, rather the circuitous route via Galt (also shown in manuscript on the map). 

The opening of the Guelph to Dundas Road began in 1827, following the founding of the Town of Guelph by John Galt. Galt instigated the development of roadway through the Township of Puslinch towards the Township of West Flamborough. The Guelph to Dundas Road, also known as Aboukir Road, was laid out following an Indigenous trail.  In July 1827, an act was passed allowing the first sale of Clergy Reserve lots in Puslinch, along the Aboukir Road. As noted in Puslinch Township Beginnings

In connection with the opening of this road through Puslinch, it was continued at the same time through the Flamboroughs.  The settlers called this the Dundas road but it was known to strangers as the Brock road, named after General Brock, whose family owned considerable land in Flamboro.  Thus it was known as the Dundas road at the north end and as the Brock road at the south end.  The name Aboukir road, seen in the patents, was the first name really given by the Crown Lands Department.  

Printing The Map In New York

The printing of two different versions of the Chewett Map (New York and London) would seem to be a practical one. Settlement in Upper Canada was expanding quickly in the 1820s and the administrators were falling far short in their abilities to generate revenue and manage the province.  Chewett was under pressure to produce his map quickly, both at home in Canada and in London for Galt and the Canada Company.  A fast ship crossing the Atlantic, would take 6 to 14 weeks in the 1820s. Adding in additional transit time to reach the coast and time for engraving the map, it would have been foreseeable that a printed version of Chewett's first manuscript map would have taken at least 4 to 6 months to make it back to Upper Canada. Given the size and elaborate nature of the Smith map, even longer. 

As such, the fast production of a smaller version of Chewett's manuscript map (Maverick map), would have been important, and was likely commenced well before the incorporation of the Canada Company in August 1825.  Publication in New York would likely have shaved a number of months off the time necessary to publish in London and see the return of the map to Southern Ontario, and the smaller 2 sheet map would have allowed faster engraving time.  One question which deserves attention is why the Maverick map was published in New York and not Canada.

Prior to 1830, there were no local printers for maps in the Province of Ontario.  In his discussion of early map printing in Ontario, Joan Winearls notes:

The printing and publishing of detailed maps of Upper Canada began very soon after intensive settlement by the British in the wake of the American Revolution. . . .  These first maps were engraved, printed, and published in Britain for the most part, or sometimes in the United States, and foreign publishers virtually controlled the market until the 1830s.  . . . 

The most important of these early maps in terms of size and accuracy was the Canada Company map drawn by James Grant Chewett of the Surveyor-General's Office; it was completed in London and released for sale in its second state of 1826.  . . .

The first abortive attempt to set up a local business for the purpose of printing maps in Upper Canada was made by Samuel Oliver Tazewell in 1831.

*  *   *

At the same time in the 1820s and I830s a few maps had been prepared by local officials such as James Grant Chewett of the Surveyor-General's Office, and these had been sent for engraving and printing to such printers as Samuel Maverick, S. Stiles, and Nathaniel Currier in New York, or to printers like Hall and Mooney in Buffalo.

Conclusion

Based primarily on the lack of reference to the Canada Company in the title of the Maverick Map, we believe that the Maverick map was issued in 1825, prior to the dissemination of information concerning the Canada Company's purchase of the Crown Lands.

Maverick 2 is the most advanced printed version of the Chewett Map, incorporating details of the 21 new Townships and providing the most accurate representation of the Madawasca River watercourse to the area being developed by the Canada Company.

The annotations on this example of Maverick 2 were most likely undertaken by senior officials in the Canada Company, who were familiar or part of the planning of proposed and  newly created roads in and around Guelph, the Canada Company's administrative headquarters in Upper Canada and Galt. 

Based upon the addition of the Guelph, Puslinch, Aboukir Road and Huron Road, and the number of Guelph Township and Puslinch Township, we date the annotations to circa 1827.  It is also possible that this is when Maverick 2 was printed.

Rarity

The map is virtually unrecorded, and we locate no auction or dealer records offering the map for sale,

What appears to be the first state of the map is noted in the Catalogue d'ouvrages sur l'histoire de l'Amérique: et en particulier sur Celle du Canada, De La Louisiane, De L'Acaedi, et autres Lieux, ci-devant connus sous le nom de Nouvelle-France / avec des notes bibliographiques, critiques, et litteraires ; en trois parties . . .  by Georges-Barthélemi Faribault (Quebec, 1837)  at page 195. Faribault places the map between the 1820 Faden Map of North America (1820) and Chewett' & Rdiout's A Map of the Province of Upper Canada and Adjacent Territories . . . published in 1826.  As such, it would appear that Faribault, writing in 1837, believed that the Maverick map pre-dated the Chewett & Ridout.

 We are aware of a single surviving example in the Norman B. Leventhal Map Center Collection at the Boston Public Library.

The second state, with the words "with the latest surveys and additions in the Surveyor General's Department" added, also appears to survive in a single recorded example at the University of Toronto Library (Fisher Rare Book Collection), which is dated 1826 in the OCLC record for the map.
