Canada has diverse geographic regions that influence its economy and industry. 1) The Prairies regions of Manitoba and Saskatchewan are major wheat producers and exporters, while British Columbia focuses on agriculture. 2) Ontario and Quebec generate 75% of Canada's electricity due to their numerous lakes, rapids and waterfalls. 3) Alberta has significant petroleum and natural gas industries, particularly from the Athabasca tar sands. Pipelines transport gas from Alberta to industrial regions in the east.
