Free Canadian Geospatial Data Sets - Canadian GIS & Geomatics
The Federal Government produces and acquires data sets in many different areas including health, agriculture, the environment and natural resources. The Government of Canada launched an open data portal [data.gc.ca] earlier this year as part of Canada's open government initiative. The portal aims to provide Canadians with a single point of access to find and download government open data sets.
