As if in response to accumulated winters of ice and snow and a desire
to escape from the weight of the polar ice cap, the people of Canada press
against their southern boundary. In 2002, most of Canada's population
of 31.4 million lived within 200 kilometres of the United States.
In fact, the inhabitants of our three biggest cities—Toronto, Montréal
and Vancouver—can drive to the border in less than two hours. Thousands
of kilometres to the north, our polar region—the Yukon, the Northwest
Territories and Nunavut—is relatively empty, embracing 41% of our land
mass but only 0.3% of our population. Human habitation in the solitary
north clings largely to scattered settlements: villages among vast expanses
of virgin ice, snow, tundra and taiga. Canadians sometimes boast that,
with only three people per square kilometre, we have one of the lowest
population densities in the world. In our highly agricultural, industrial
and urban south, however, population densities are similar to those of
many regions in the United States.
