Name a major natural resource found in Canada.

Oil is a major natural resource found in Canada and plays a significant role in the country's economy. Canada is home to vast reserves of oil, particularly in the Alberta tar sands, which are among the largest oil reserves in the world. The extraction and production of oil contribute immensely to job creation, energy production, and government revenues through taxation. Moreover, Canada is also one of the largest exporters of oil to other countries, particularly the United States.

While gold, diamonds, and coal are also important natural resources in Canada, they do not match the scale and economic impact of the oil industry. Gold and diamonds can be valuable, but their contribution is smaller compared to that of oil. Coal is significant too, especially for energy production, but again, the oil sector is paramount in terms of overall economic impact and global significance. This distinction emphasizes the critical role oil plays in Canada's natural resources landscape.
