Canada: A Regional GeographyDavid Rossiter, Western Washington University

A Northern Silver Mine – F. Carmichael

Five Themes

• Location– relative / absolute

• Place– human / physical

• Human-Environment interactions– adaptation, modification, dependence

• Movement

• Regions

The Physical Base

• Geology• Topography• Soils• Vegetation• Climate

• Fundamental to understanding Canada’s Human Geography

The Late Wisconsin Ice Age

• Last ice age in the territory of Canada

• Southern limit: Wisconsin

• Covered vast majority of Canada’s territory

• Reached maximum extent 18,000 years ago

• Started to recede 15,000 years ago

• Last remnants in Rockies 7,000 years ago

Till and erratic – Peggy’s Cove, N.S.

Drumlin - Alberta

Esker - Manitoba

Glacial Lake – Jasper, AB

Great Lakes – St. Lawrence Lowlands

- Quebec City to Windsor- Smallest physiographic region: < 2% of Canada’s landmass

Q

W

Great Lakes – St. Lawrence Lowlands

• Geology: sedimentary rock (strata) and glacial deposits

• Flat, rolling topography

• Good soil

• Moderate climate, good growing season– humid and hot summer / cold winter

• Proximity to USA

• HEARTLAND

Appalachian Uplands

Appalachian Uplands

• Northern section of Appalachian Mountians

• ~2% of Canada’s land mass

• Rounded uplands and narrow river valleys

• Rocky, shallow soils

• Mixed forest

• Cool, maritime climate– short summer, wet winter

NFLD – North Coast

Canadian Shield

Canadian Shield

• Largest region – ~50% of Canada• Geological core of North America

– Underlies other physiographic regions

• Precambrian rocks > 3 billion yrs old• Widespread evidence of glaciation• Shallow soils, exposed granite• Mixed and Boreal forest• Northern continental climate

– hot, short summer / cold, long winter

Quebec – North Shore

Hudson Bay Lowlands

Hudson Bay Lowlands

• ~3.5% of the area of Canada

• Youngest phyisographic region in Canada

• Made up of muskeg (wet peatland)

• Interrupted by low ridges of sand and gravel

• Poorly drained due to level surface

• Northern climate – maritime influence– short, warm summer / long, cold winter

Muskeg – Hudson Bay Lowlands

Delta – James Bay Coast

Interior Plains

Interior Plains

• ~20% of Canada’s landmass• Geologic base of sedimentary rock• Land shaped by glacial and hydrological

processes – river valleys• Slope east to west – Hudson Bay Wtshd• Rich soils in south• Oil and gas deposits• Continental climate – moderate precip.

– hot summer / cold winter

Wheat field outside Winnipeg

Near Lesser Slave Lake, Alberta

South Saskatchewan River

Arctic Lands

Arctic Lands cont’d…

• ~25% of Canada’s territory• Coastal plains (Lowlands)• Plateaux and mountains (Innuitian)• Mainly sedimentary rock• Ground permanently frozen - permafrost• Glaciers still active – ‘calved’ into icebergs• Main geomorphic process – frost action• Coooold, areas of polar desert

Mountains – Baffin Island

Cordillera

Cordillera

• ~16% of Canada’s territory

• Formed 40-80 million years ago– collision between NA and Pacific plates– Rockies: up-thrust sedimentary rocks– Coast mountains: volcanic activity

• Coast an active fault zone– earthquakes, volcanoes– part of Pacific Rim of Fire

Cordillera cont’d…

• Glaciers remain in high alpine areas

• Fertile river valleys and deltas (particularly SW corner of BC)

• Largely coniferous forest cover

• Multiple micro-climates– warmer, wetter on coast– colder, drier in interior

Sedimentary rocks at Lake Louise

The Barrier – Coast Mountains, BC

Where are all the people?

Short answer:

• In cities, near the USA– ~80% of Canadians live in cities (100,000+)– ~80% of Canadians live within 100km of USA

Pop. Density: 2001

Current Pop: 32mil

Where are all the people?

Longer answer:

• All over– cities draw on resources of hinterland– north dominated by resource towns and

regional service centres

Three Popular Explanations

• Staples Development– Canada developed by resource extraction

• Heartland-hinterland patterns– International, national, regional scales

• Physical disunity (or, unity despite geography)– Human settlement in patches, difference from

USA

Storehouse of Raw Materials

• “Hewers of wood and drawers of water”

• Earliest European interests were more commercial than colonial – fish, fur

• Colonial settlement shaped by staples extraction and export

• Trade with “mother countries” (Britain, France), then USA

• Resources still major economic sector

Forestry Communities: 1996

Mining Communities: 1996

Oil and Gas Communities: 1996

Metropolitan Heartlands

• A urban nation– against stereotype– diverse

• Old(ish)– Quebec City (1608)

• Young– Vancouver (1886)

• Draw on hinterland’s resources– insurance, finance,

manufacturing

Financial Services

Canada’s Regional Character

• Socio-economic regions:– Shaped by:

• topography• political boundaries• language• historical patterns

• Heartland-hinterland relations

• Regional identities powerful– Political considerations

This place wasn’t always Canada

• 1000s of years of Native presence• European contact over centuries

– late-15th C in east, mid-18th C in west

• Resettlement by Europeans through:– force– treaty– depopulation (disease)

• Historical geographies matter: socially, politically, ecologically

Current “Geographical” Issues

• Native land claims– BC particularly, but not exclusively

• Environmental “crises”– forestry, climate, energy

• Federal “balance”– fiscal, other arrangements

• Cities’ growth– planning, opportunity for newcomers
