The first of the two uses is the use of olive oil for cooking.
The difference between canola oil and olive oil lies in the fat content.
Olive oil has monounsaturated fat whereas canola oil contains polyunsaturated fat.
Monounsaturated fat is good for your heart as it slows down the aging process and lowers the cholesterol levels and polyunsaturated fat are good for the heart because it helps the heart pump blood.
The second use of canola oil is for tortilla chips. The chips are made with corn meal or corn flour and then seasoned with Mexican seasoning.
