and water supplies, and formidable challenges, such as rugged terrains,
severe climates, and great distances.
Most of the basic landforms of Canada share continental patterns
of running in a north-south direction, creating another obstacle
for people as they set about carving out a distinctive nation. The
country’s physiographic regions vary dramatically from east to
west and from south to north. The regional variety has shaped
exploration, habitation, economic development, and relationships
with Americans in contiguous regions. Starting from the Atlantic
seaboard, the areas defined by the current Atlantic Provinces and part
of Quebec, the land is an extension of the vast Appalachian region
that sweeps north to south along the continent’s spine. The mountain
ranges and valleys that dominate this region, coupled with the
extensive coastal area of the Atlantic Ocean and Gulf of St. Lawrence,
lend themselves to modest agricultural pursuits, forestry, mining, and
fishing. The Great Lakes–St. Lawrence lowlands, an area bordering
the interior lake systems and St. Lawrence River, or the extreme
southern portions of Quebec and the southern peninsular region of
Ontario, is one of the most fertile and temperate areas in Canada. It is
also the location of the country’s two largest cities, home to most of
its population, and its industrial heartland. When Canadians speak of
central Canada, this is the region they have in mind.
Sweeping north of both of these regions in a dramatic U-shape is
the Canadian Shield, the country’s dominant landform. Also called
the Precambrian Shield, it is a mass of igneous rock that blankets
roughly half of Canada’s geography. With Hudson Bay as the center
of the cup, it encompasses Labrador, most of Quebec, Ontario, and
Manitoba, and much of Nunavut and the Northwest Territories.
Scoured by thousands of years of glaciation, the Shield is
characterized by thin soil, a rugged terrain that includes hills and
valleys, honeycombed streams and rivers, and seemingly countless
lakes and ponds. Virtually uninhabitable, the Shield created a
formidable obstacle to exploration, settlement, and the construction
of transportation systems such as railroads and highways. At the
same time, the Shield is an area of immense beauty and wilderness;
it is also the vast storehouse of immense resource wealth, including
minerals such as nickel, copper, iron, lead, zinc, and uranium. For
centuries its fur-bearing animals were trapped by the millions to drive
a lucrative fur trade. Its vast timber stands have propelled one of the
