Canada is the second-largest country in the world by land area, covering approximately 9.98 million km², with a population of about 40 million people. It extends from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward to the Arctic Ocean. Canada’s geography is highly diverse and can be divided into several major regions: the Atlantic coastal plains, the Great Lakes–St. Lawrence Lowlands, the Canadian Shield, the Interior Plains, the Cordillera in the west, and the Arctic Archipelago in the north. The Canadian Shield alone covers nearly half of the country’s land area and consists of ancient rock formations, forests and numerous lakes. Major mountain systems such as the Rocky Mountains dominate western Canada, while the Arctic north is characterized by tundra and permafrost. Canada’s climate ranges from temperate in the south to subarctic and arctic in the north, influencing patterns of settlement and land use.
Historically, Canada was inhabited for thousands of years by Indigenous peoples prior to European arrival. Beginning in the 16th century, French and later British colonization led to the establishment of fur trading networks and agricultural settlements along the St. Lawrence River. Control of the territory shifted to Britain in the 18th century, and Canada gradually developed into a self-governing dominion before achieving full sovereignty in the 20th century. Early economic development was strongly linked to natural resources, including fur, timber and fisheries, which shaped patterns of settlement and trade.
Today, the primary sector remains a fundamental component of Canada’s economy, although services and manufacturing dominate overall GDP. Agriculture, forestry and fisheries together contribute roughly 6–7% of GDP and play a crucial role in exports and rural employment.
Agriculture occupies about 6.2% of Canada’s land area, primarily in the Prairie provinces of Alberta, Saskatchewan and Manitoba, where vast plains support large-scale grain production. Canada is one of the world’s leading producers and exporters of wheat, canola and barley. Livestock farming, particularly cattle and dairy, is also significant.
Forestry is one of Canada’s most important natural resource industries. Forests cover approximately 38% of the country’s land area, making Canada home to nearly 9% of the world’s forest resources. The sector contributes about 2% of GDP and supports hundreds of thousands of jobs, particularly in provinces such as British Columbia and Quebec. Timber, pulp and paper are major export products.
Fisheries have historically been vital, especially along the Atlantic coast and in the Pacific region. The sector contributes less than 1% of GDP, yet it remains important for coastal communities. Key products include salmon, lobster and cod, harvested from both marine and freshwater environments.
Overall, Canada’s primary sector reflects the influence of its vast geography and natural resource endowment. Fertile plains support large-scale agriculture, extensive forests underpin the timber industry, and long coastlines sustain fisheries. Despite the dominance of services and industry, these sectors remain essential for exports, regional development and environmental management.
