The Constitution Act, 1982 doesn’t lay out how elections or electoral finances or voting or campaigns, etc are to be handled. The Constitution only says that elections have to happen every 5 years (s.4 of the Charter and s. 50) and anyone who can vote can be a MP/MPP/MLA (s.3 of the Charter), the conditions to suspend elections (s.4(2) of the Charter), and how many and how ridings are created for Ontario, Quebec, New Brunswick, and Nova Scotia(s. 40), and electoral officers (s.83) for Ontario and Quebec. The ridings and the electoral officers are subject to federal or provincial law.
Section 51(1) does lay how to readjust the ridings.
On a fun fact about the Constitution. Many people think it takes 7 provinces with 50 percent of the population to change the Constitution. Certain sections can be changed with a simple vote in the House and/or Provincial Legislature to change.

How elections are run is decided by either the Elections Act at the Federal level or a Province’s version of the Elections Act.




Generally, budgets and throne speeches are considered automatic confidence votes. Other than that, the House can either propose a non-confidence vote or the Government can designate a vote to be a confidence vote. Generally, the games of chicken over confidence votes happen a lot in minority governments.
