Quebec Open Data
The Québec government, along with many of the municipalities of like Laval, Quebec City and Sherbrooke (all had their own open data portals) joined forces in 2016 to create the Québec open data portal. Many other municipalities then followed, and now the site contains almost a thousand different data sets.
Therefore Quebec Open Data should always be the best starting point when looking for data for places in the Province of Quebec.
