Declaration of war by Canada

A declaration of war by Canada is a formal declaration issued by the Government of Canada (the federal Crown-in-Council) indicating that a state of war exists between Canada and another nation. It is an exercise of the royal prerogative on the constitutional advice of the ministers of the Crown in Cabinet and does not require the direct approval of the Parliament of Canada, though such can be sought by the government. Since gaining the authority to declare war as a consequence of the Statute of Westminster, 1931, Canada has done so only during the Second World War.^[1]
