Population distribution:
vast majority of Canadians are positioned in a discontinuous band within approximately 300 km of the southern border with the United States; the most populated province is Ontario, followed by Quebec and British Columbia

Natural hazards:
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

volcanism: the vast majority of volcanoes in Western Canada's Coast Mountains remain dormant

Environment - current issues:
metal smelting, coal-burning utilities, and vehicle emissions impacting agricultural and forest productivity; air pollution and resulting acid rain severely affecting lakes and damaging forests; ocean waters becoming contaminated due to agricultural, industrial, mining, and forestry activities

Geography - note:

note 1: second-largest country in world (after Russia) and largest in the Americas; strategic location between Russia and US via north polar route; approximately 90% of the population is concentrated within 160 km (100 mi) of the US border

note 2: Canada has more fresh water than any other country and almost 9% of Canadian territory is water; Canada has at least 2 million and possibly over 3 million lakes - that is more than all other countries combined
