What are Tar Sands? Tar sands (or oil sands) are a low-grade petroleum deposit, a very viscous mix of clay, sand, water and oil-rich bitumen (think asphalt).1 Enormous tar sands deposits lie under Alberta, Canada's boreal forests. Canada has the third largest oil reserves in the world, behind only Saudi Arabia and Venezuela.
