<<Disclaimer: Verify this information before applying it to your situation.>> Joan--I'm glad to know that the Canadians are strict with their government regulations (protecting the consumer I hope). One problem with canola oil in constant use might be it's very high polyunsaturates. At any rate, I think it's best to use cold-pressed oils. Some health-minded people like to use flax oil in salad dressings or flax seeds ground up. I don't know if that has been discussed on this list. I use some cold pressed olive oil when I can stand the flavor. Mary J.
