Canada Geography Profile 2012
Canada borders the United States in the south and stretches northward, past the Arctic Circle, to the Beaufort Sea and the Arctic Ocean. The east coast is formed largely by the Atlantic Ocean, including such arms as the Gulf of St. Lawrence, the Labrador Sea, Davis Strait, and Baffin Bay. Western Canada fronts on the Pacific Ocean and borders Alaska. The 5,527-mile (8,895-km) Canada-United States boundary, including 1,540 miles (2,478 km) along Alaska, is the longest between any two nations in the world.

Most of Canada has either a polar or a subpolar climate. These two types of climate prevail throughout the northern and central parts of the country, including the northern sections of the mainland provinces. Winters here are long and bitterly cold, with average January temperatures ranging from roughly -10° to -35° F. (-23° to -37° C.), depending on location. Lows of -50° to -60° F. (-46° to -51° C.) are common. Summers are brief and cool, with occasional warm periods. July temperatures average between 40° and 60° F. (4° and 16° C.). Precipitation is light, particulary in the far north, and consists mainly of snow.
The Pacific coast, with cool waters offshore and protected from the Arctic cold by high mountains, has the most moderate climate in Canada. Rarely is the weather severely hot or cold. Summers are cool to warm, with average July readings near 60° F. (16° C.). Winters are mild, all months averaging above freezing. Rainfall is abundant—more than 100 inches (2,540 mm) a year in some areas exposed directly to the sea. Much cloudiness also marks the weather, especially during winter. Winter is also the period of greatest precipitation.
Away from the coast in the mountainous region of southern British Columbia the climate is highly varied, but markedly colder and drier. The variation stems mainly from differences in elevation and, to a lesser extent, latitude. The windward sides of mountains receive considerably more precipitation than the leeward sides.
A type of continental climate prevails throughout the prairies of southern Alberta, Saskatchewan, and Manitoba, where winters are severe. In the western part, the severity is moderated somewhat by warm chinook winds from the Rockies. January temperatures average about 0° to 10° F. (-18° to -12° C.), depending on location. Summers are warm throughout the prairies, July averaging near 70° F. (21° C.). There are also days of 90° to 100° F. (32° to 38° C.). Precipitation is variable in this relatively dry region, but usually averages between 10 and 20 inches (255 and 510 mm) a year.
The southern parts of Ontario and Quebec have a humid continental type of climate. Winters are long and cold, January averaging about 5° to 15° F. (-15° to -9° C.). Summers are warm and somewhat longer than in most other regions in Canada. Precipitation is abundant, about 30 to 40 inches (760 to 1,020 mm) a year. Snowfall is heavy, especially in southern Quebec.
The climate of the Atlantic Provinces resembles that of southern Quebec and Ontario, but is modified by the ocean. Summers are cool to warm; winters are cold, snowy, and damp. Fog is prevalent in many areas. Precipitation is heavy; at Halifax, Nova Scotia, for example, it averages more than 50 inches (1,270 mm) per year.
mostly plains with mountains in west and lowlands in southeast
iron ore, nickel, zinc, copper, gold, lead, molybdenum, potash, diamonds, silver, fish, timber, wildlife, coal, petroleum, natural gas, hydropower
continuous permafrost in north is a serious obstacle to development; cyclonic storms form east of the Rocky Mountains, a result of the mixing of air masses from the Arctic, Pacific, and North American interior, and produce most of the country's rain and snow east of the mountains
air pollution and resulting acid rain severely affecting lakes and damaging forests; metal smelting, coal-burning utilities, and vehicle emissions impacting on agricultural and forest productivity; ocean waters becoming contaminated due to agricultural, industrial, mining, and forestry activities
second-largest country in world (after Russia); strategic location between Russia and US via north polar route; approximately 90% of the population is concentrated within 160 km of the US border
