Geospatial Ontario (GEO) helps public and private organizations and individuals find, access and share geographic data. GEO also coordinates the collection of aerial photography for Ontario.
Find Ontario's authoritative geospatial data using Ontario GeoHub which includes options to download the data or use a web service in geospatial software. For imagery of the Grand River watershed search for "SWOOP" data products.
In addition to data available from GEO, or what the province has designated as Open Data, the MNR provides access to several data sets for non-commercial end-use.
