Provinces and territories of Canada Top-level subdivisions of Canada

The provinces and territories of Canada are the sub-national governments within the geographical areas of Canada under the authority of the Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada —were united to form a federated colony, becoming 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. Together, the provinces and territories make up the world's second-largest country by area.

Nunavut Territory of Canada

Nunavut is the newest, largest, and most northerly territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the Nunavut Act and the Nunavut Land Claims Agreement Act, though the boundaries had been drawn in 1993. The creation of Nunavut resulted in the first major change to Canada's political map since the incorporation of the province of Newfoundland in 1949.

Tibbitt to Contwoyto Winter Road highway in the Northwest Territories

Tibbitt to Contwoyto Winter Road is an annual ice road first built in 1982 to service mines and exploration activities in the Northwest Territories and Nunavut in Northern Canada. Between 400 and 600 km long, the road is said to be the world's longest heavy haul ice road and operates for eight to ten weeks starting in the last week of January. Most of the road (85%–87%) is built over frozen lakes, 495 km (308 mi), with the remaining 73 km (45 mi) built on over 64 land portages between lakes. This ice road was the location of the first season of Ice Road Truckers.
