Canada's journey from a union of four colonies to a nation spanning a continent was a gradual process spanning over 80 years. Below is the chronological order in which provinces and territories entered Confederation.
| Province / Territory | Date of Entry |
|---|---|
| Ontario | July 1, 1867 |
| Quebec | July 1, 1867 |
| Nova Scotia | July 1, 1867 |
| New Brunswick | July 1, 1867 |
| Manitoba | July 15, 1870 |
| British Columbia | July 20, 1871 |
| Prince Edward Island | July 1, 1873 |
| Saskatchewan | September 1, 1905 |
| Alberta | September 1, 1905 |
| Newfoundland and Labrador | March 31, 1949 |
Note: The three territories—Northwest Territories (1870), Yukon (1898), and Nunavut (1999)—were created by federal statute rather than joining via constitutional negotiation, though the Northwest Territories originally entered as part of the 1870 transfer of Rupert's Land.
