Canada is a federation composed of ten provinces and three territories; in turn, these may be grouped into regions. 
Western Canada consists of British Columbia and the three Prairie provinces (Alberta, Saskatchewan, and Manitoba). Central Canada consists of Quebec and Ontario. Atlantic Canada consists of the three Maritime provinces (New Brunswick, Prince Edward Island, and Nova Scotia), along with Newfoundland and Labrador. Eastern Canada refers to Central Canada and Atlantic Canada together. Three territories (Yukon, Northwest Territories, and Nunavut) make up Northern Canada. Provinces have more autonomy than territories. Each has its own provincial or territorial symbols.
The provinces are responsible for most of Canada's social programs (such as health care, education, and welfare) and together collect more revenue than the federal government, an almost unique structure among federations in the world. Using its spending powers, the federal government can initiate national policies in provincial areas, such as the Canada Health Act; the provinces can opt out of these, but rarely do so in practice. Equalization payments are made by the federal government to ensure that reasonably uniform standards of services and taxation are kept between the richer and poorer provinces.
All provinces have unicameral, elected legislatures headed by a Premier selected in the same way as the Prime Minister of Canada. Each province also has a Lieutenant-Governor representing the Queen, analogous to the Governor General of Canada. The Lieutenant-Governor is appointed on the recommendation of the Prime Minister of Canada, though with increasing levels of consultation with provincial governments in recent years.
