The act stipulates a “province”. As regards a “region”, in Quebec, there are 17 regions and in each and every single province, there are areas that are designated as a “region”. As regards this, the governor in council must consult the provinces and territories to agree upon the designated regions. You are talking about the federal designation of a province or region, but I wish to specify that a region is found within a province.
