The fact that canola oil is processed, isn't a very good argument against it. The diet espoused on this site says to avoid processed foods - yes. But we aren't avoiding processed foods for the sake that they're processed -- we're avoiding them because they are harmful in some way. Saying Canola oil is bad BECAUSE it is processed is a non starter.
The fact that someone makes money off of Canola oil is another irrelevant point. People make money off of grass-fed beef, coconuts, etc. as well. This has nothing to do with whether they are good or bad for you.
