The Canadian Heraldic Authority is part of the Canadian honours system under the Canadian monarch, whose authority is exercised by the Governor General of Canada. The authority is responsible for the creation and granting of new coats of arms, flags, and badges for Canadian citizens, government agencies, municipal, civic and other corporate bodies. The authority also registers existing armorial bearings granted by other recognized heraldic authorities, approves military badges, flags, and other insignia of the Canadian Forces, and provides information on heraldic practices. It is well known for its innovative designs, many incorporating First Nations symbolism.

The orders, decorations, and medals of Canada comprise a complex system by which Canadians are honoured by the country's sovereign for actions or deeds that benefit their community or the country at large. Modelled on its British predecessor, the structure originated in the 1930s, but began to come to full fruition at the time of Canada's centennial in 1967, with the establishment of the Order of Canada, and has since grown in both size and scope to include dynastic and national orders, state, civil, and military decorations; and various campaign medals. The monarch in right of each Canadian province also issues distinct orders and medals to honour residents for work performed in just their province. The provincial honours, as with some of their national counterparts, grant the use of post-nominal letters and or supporters and other devices to be used on personal coats of arms.
