Editing Constitution of Canada (section)

===Amending formula===
{{Main|Amendments to the Constitution of Canada}}
Instead of the usual parliamentary procedure, which includes the monarch's formal [[royal assent]] for enacting legislation, amendments to any of the acts that collectively form the constitution must be done in accordance with Part V of the ''Constitution Act, 1982'', which provides for five different amending formulae. Amendments can be brought forward under section 46(1) by any province or the federal legislature. The general formula set out in section 38(1), known as the "7/50 formula", requires: (a) assent from both the House of Commons and the Senate; (b) the approval of two-thirds of the provincial legislatures (at least seven provinces) representing at least 50 per cent of the population of the provinces (effectively, this would include at least Quebec or Ontario, as they account for more than half of the [[population of Canada]]). This formula specifically applies to amendments related to the proportionate representation in Parliament, powers, selection, and composition of the Senate, the Supreme Court, and the addition of provinces or territories.

The other amendment formulae are for particular cases as provided by the act. An amendment related to the [[Monarchy of Canada|Office of the King]], the use of either official language (subject to section 43), the amending formula itself, or the composition of the Supreme Court, must be adopted by unanimous consent of all the provinces in accordance with section 41. In the case of an amendment related to provincial boundaries or the use of an official language within a province alone, the amendment must be passed by the legislatures affected by the amendment (section 43). In the case of an amendment that affects the federal government only, the amendment does not need the approval of the provinces (section 44). Similarly, amendments affecting a provincial government alone (section 45) do not need the approval of the Parliament or the other provinces.
