The timeline of elections in Canada covers all the provincial, territorial and federal elections from when each province was joined Confederation through to the present day. The table below indicates which party won the election. Several provinces held elections before joining Canada, but only their post-Confederation elections are shown. These include:
- Lower Canada held 15 elections for its Legislative Assembly, from 1792 to 1835;
- Upper Canada held 13 elections to its Legislative Assembly, from 1792 to 1836;
- the Province of Canada held 8 elections for its Legislative Assembly from 1841 to 1863;
- New Brunswick's first 21 elections, beginning in 1785 (the 21st Legislative Assembly of New Brunswick was elected in 1866, one year before Confederation, and continued until 1870, three years after Confederation);
- Nova Scotia's first 22 elections, beginning in 1758;
- Prince Edward Island's first 25 elections, beginning in 1773; and
- Newfoundland's first 29 elections, beginning in 1832.
The most recent election is shown with a box limited to four years of government, as the federal government and all provinces and territories have fixed election dates every four years. However, elections can be called at any time by an incumbent government. Thus, the box is shown as running until the next scheduled election, but one could still be earlier if the government falls due to a motion of no confidence, or if the governing party calls an early election. The maximum length of office as set by the constitution is five years.
