Canada has the third-largest volume of proven oil reserves in the world. Over 95% of these reserves are located in four oil sands deposits in Alberta, all overlaid by administrative boundaries, or oil sands areas, of the same name. They include the Athabasca deposit, Cold Lake deposit, Peace River deposit, and the Surface Mineable Oil Sands Region (Mineable Region), a subregion within the Athabasca Oil Sands Area.
