The office is not outlined in any of the documents that constitute the written portion of the Constitution of Canada; executive authority is formally vested in the sovereign and exercised on his or her behalf by the Governor General. The prime ministership is part of Canada's constitutional convention tradition. The office was initially modelled after the job as it existed in Britain at the time. Sir John A. Macdonald was formally commissioned by Lord Monck on May 24, 1867 to form the first Canadian Government under Confederation. On July 1, 1867 the First Ministry assumed office.[2]
The date for which a Prime Minister begins his or her term has been determined by the date that he or she is sworn into his or her portfolio, as an oath of office as Prime Minister is not required.[3] However, starting in 1957 the incoming Prime Minister has sworn an oath as Prime Minister; as of 2006, this tradition has continued.[3] Before 1920, the Prime Ministers' resignations were accepted immediately by the Governor General, and the last day of the ministries were the date he died, or the date of resignation.[3] Since 1920, the outgoing Prime Minister has only formally resigned when the new government is ready to be formed.[3] The Interpretation Act of 1967 states that "where an appointment is made effective or terminates on a specified day, that appointment is considered to be effective or to terminate after the end of the previous day."[3] Although, traditionally, the outgoing Prime Minister formally resigns only hours before the incoming ministry swears their oaths, both during the day, the ministries are effectively changed at midnight, the night before. Some sources, including the Parliament of Canada, apply this convention as far back as 1917.[4]
