Baby steps. 
I had a very similar scenario when my sister-in-law came home with a GIGABYTE bottle of ranch dressing Costco.  First ingredient: canola oil.

I just said that our family wouldn’t, and shouldn’t eat anything much seed oil in it. 

A day later, I asked her if she knew the difference between rapeseed oil and canola oil (same thing) She said, no, so I asked her if she wanted to?
Even the Wiki page paints an ugly picture about “canola”. 
Start there. If you want to know more, let me know.
