Canada has at least 9 substantively different Open Government Licences in active use: federal, Ontario, BC, Alberta, plus municipal (Toronto, Guelph, Winnipeg, Niagara Region, York Region). Attribution and reuse terms differ subtly — the OpenStreetMap Foundation maintains a compatibility list. For Candid KW-region work, the practical stack is OGL-Canada + OGL-Ontario + occasional municipal feeds.
