Ontario Geological Survey's GSEarth provides geoscience data, collected by the Mines and Minerals division, which can be viewed using user-friendly geographic information programs such as Google Earth.

GSC has released geological mapsin digital files through the GEOSCAN online database. When searching for maps, use the Advanced search to search specifically the “A” Series maps or the Canadian Geoscience maps. The “A” Series maps are those that focus on Geology and have been recently replaced with the GSC Canadian Geoscience Map. Most of the maps from these series show the geology of a specific area at a larger scale. These are also available in paper format in the GSC “A” Seriesmap cabinetin the library. Below are some of the more general maps that cover all of Canada from the “A” Series.
