  The position of prime minister is not outlined in any Canadian constitutional document and is mentioned only in a few sections of the Constitution Act, 1982, and in the Letters Patent, 1947 issued by King George VI. The office and its functions are instead governed by constitutional conventions and modelled on the same office in the United Kingdom.
