The Ministry of Natural Resources fonds consists of 33 large-scale plans (registered 1793-1844; incorporating annotations dating up to 1981) created by the Surveyor General’s Office documenting 23 townships along the north shore of Lake Erie. The plans show lot and concession numbers, major roads, First Nations settlements, mills, creeks, swamps, and local geographic information. Many maps contain an assortment of notes on specific geographic features and have settler names written in; others are blank. The maps were frequently used as working documents, and bear revisions and annotations dating years after their apparent creation.
Seven maps lack any sort of date; in these cases, the Archives of Ontario’s estimation has been used. In other cases, a map bears dates of annotation but no written date of registration; in these cases the date range of the annotations has been used as an approximate date.
