Here's a link to the FDA proposal on Canola oil.

http://www.fda.gov/bbs/topics/ANSWERS/ANS00198.html

It appears that canola oil, aka rapeseed oil, wasn't safe for use due to the
high erucic acid content. Then, the Canadians genetically modified,
selectively bred, the rape plant to lower the erucic acid content so that
now, as the FDA says, it is generally recognized as safe.
