George Tremaine operated a map publishing business in Toronto during the 1850s and 1860s, and created maps of a number of counties across Ontario for subscribers. Fifty-four counties are known to have been mapped between 1856 and 1888. Thirty-two are of Ontario and the rest were spread throughout Eastern Canada. They included such features as the survey grid, roads, railroads, towns, buildings and the names of the rural residents. They also contained agricultural, cultural and natural features. 1
