Geography of Canada - Natural Resources

Natural Resources

Canada's abundance of natural resources is reflected in their continued importance in the economy of Canada. Major resource-based industries are fisheries, forestry, agriculture, petroleum products and mining.

The fisheries industry has historically been one of Canada's strongest. Unmatched cod stocks on the Grand Banks off Newfoundland launched this industry in the 16th century. Today these stocks are nearly depleted, and their conservation has become a preoccupation of the Atlantic Provinces. On the West Coast, tuna stocks are now restricted. The less depleted (but still greatly diminished) salmon population continues to drive a strong fisheries industry. Canada claims 12 nautical miles (22 km) of territorial sea, a contiguous zone of 24 nautical miles (44 km), an exclusive economic zone of 200 nautical miles (370 km) and a continental shelf of 200 nautical miles (370 km) or to the edge of the continental margin.

Forestry has long been a major industry in Canada. Forest products contribute one fifth of the nation's exports. The provinces with the largest forestry industries are British Columbia, Ontario and Quebec. Fifty-four percent of Canada's land area is covered in forest. The boreal forests account for four-fifths of Canada's forestland.

Five per cent of Canada's land area is arable, none of which is for permanent crops. Three per cent of Canada's land area is covered by permanent pastures. Canada has 7,200 square kilometres (2,800 mi2) of irrigated land (1993 estimate). Agricultural regions in Canada include the Canadian Prairies, the Lower Mainland and interior plateau of British Columbia, the St. Lawrence Basin and the Canadian Maritimes. Main crops in Canada include flax, oats, wheat, maize, barley, sugar beets and rye in the prairies; flax and maize in Western Ontario; Oats and potatoes in the Maritimes. Fruit and vegetables are grown primarily in the Annapolis Valley of Nova Scotia, Southwestern Ontario, the Golden Horseshoe region of Ontario, along the south coast of Georgian Bay and in the Okanagan Valley of British Columbia. Cattle and sheep are raised in the valleys of British Columbia. Cattle, sheep and hogs are raised on the prairies, cattle and hogs in Western Ontario, sheep and hogs in Quebec, and sheep in the Maritimes. There are significant dairy regions in central Nova Scotia, southern New Brunswick, the St. Lawrence Valley, northeastern Ontario, southwestern Ontario, the Red River valley of Manitoba and the valleys of eastern British Columbia, on Vancouver Island and the Lower mainland.

Fossil fuels are a more recently developed resource in Canada, with oil and gas being extracted from deposits in the Western Canadian Sedimentary Basin since the mid 1900s. While Canada's crude oil deposits are fewer, technological developments in recent decades have opened up oil production in Alberta's Oil Sands to the point where Canada now has some of the largest reserves of oil in the world. In other forms, Canadian industry has a long history of extracting large coal and natural gas reserves.

Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc, copper, gold, lead, molybdenum, and uranium reserves. Large diamond concentrations have been recently developed in the Arctic, making Canada one of the world's largest producers. Throughout the Shield there are many mining towns extracting these minerals. The largest, and best known, is Sudbury, Ontario. Sudbury is an exception to the normal process of forming minerals in the Shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater. The nearby, but less known Temagami Magnetic Anomaly has striking similarities to the Sudbury Basin. Its magnetic anomalies are very similar to the Sudbury Basin, and so it could be a second metal-rich impact crater. The Shield is also covered by vast boreal forests that support an important logging industry.

Canada's many rivers have afforded extensive development of hydroelectric power. Extensively developed in British Columbia, Ontario, Quebec and Labrador, the many dams have long provided a clean, dependable source of energy.
