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.
