How many provinces and territories make up Canada?

Canada's geography is divided into administrative divisions known as provinces and territories that are responsible for delivery of sub-national governance. When Canada was formed in 1867, three provinces of British North America — New Brunswick, Nova Scotia and the Province of Canada (which, on the formation of Canada, was divided into Ontario and Quebec) — were united to form a federated colony, which eventually became a sovereign nation in the next century.

Over its history, Canada's international borders have changed several times, and the country has grown from the original four provinces to the current ten provinces and three territories. The ten provinces are Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, Quebec, and Saskatchewan. Several of the provinces were former British colonies, Quebec was originally a French colony, while others were added as Canada grew. The three territories are Northwest Territories, Nunavut, and Yukon, which govern the rest of the area of the former British North America. Together, the provinces and territories make up the world's second-largest country by area.
