To hunt migratory game birds in Canada, you must have a valid federal migratory game bird hunting (MGBH) permit on which the Canadian Wildlife Habitat Conservation (CWHC) stamp appears. The MGBH permit is valid anywhere in Canada.
You must be able to show the permit to game officers upon request. To be valid, the permit (physical or electronic) no longer needs to be signed. You must carry the permit with you at all times, either in physical or electronic PDF format, when hunting or when in possession of unpreserved migratory game birds or any murres, in a place other than your residence.
