British North America Acts
The Constitution of Canada resulted from the passage of several British North America Acts from 1867 to the Canada Act 1982, the act that formally severed British Parliament's ability to amend the Canadian constitution. The Canadian constitution includes specific legislative acts as mentioned in section 52(2) of the Constitution Act, 1982. However, some documents not explicitly listed in section 52(2) are also considered constitutional documents in Canada, entrenched via reference; such as the Proclamation of 1763. Although Canada's constitution includes a number of different statutes, amendments, and references, some constitutional rules that exist in Canada is derived from unwritten sources and constitutional conventions.
