The United States is nominally founded on the ideal that governments derive their just powers from the consent of the governed. The American federal government exists because the people of the United States chose to allow it to exist. The Constitution and its amendments recognize that persons have innate rights, that the American people collectively possess sovereignty, and that the government can only exercise the authorities that are granted to it by the people.
Canada never had a “We the People” moment. The Crown that governs Canada has existed since the Middle Ages. The Crown is an abstract legal entity that possesses all sovereign authority in Canada. 1867 was not a revolution, but simply a transfer of colonial management from London to Ottawa. To remove the right to execute authority from the Crown (while the Crown remains the source of the authority) a document signed by the monarch is required, either through the form of a Constitution or legislation. The Canadian Constitution removes almost all execution of authority from the Crown and gives it to the three branches of government. The Charter of Rights and Freedoms limits what those branches can do. Individual pieces of legislation remove certain powers from the Crown and invest them in ministers. Collectively, the Cabinet and the PM govern like near-monarchs because they exercise all the powers of the Crown. They are likewise limited by the law, the Constitution, and the rights that are recognized by the Charter. Note that these documents do not grant power to the government on behalf of the people: they limit the Crown’s power. Americans have collectively entered into a social contract to establish a government; Canadians have entered into a social contract with their government.
Why does this matter? In my patriotic opinion, too often American ideas filter northwards without being adapted to Canada’s unique legal and governmental structure. Canadians and Americans do not have the same rights. The two nations have different national narratives concerning rights. The British Loyalists moved north to maintain their British rights when the American Patriots rebelled to assert their American rights. My fellow Canadians are more than welcome to use their voice and vote to stand up for what they consider to be their rights, but they should know what defined rights they currently have.
