Eric Atkins you totally missed out on the landmark genetic work by Allelix Crop Technologies (ACT) to make Candian rapeseed a worldwide edible crop called Canola the in the late 1980 and through the 1990s.  The company was led by Dr. John Evans.  I know as I worked there on various scientific projects to achieve this goal.  ACT was then bought by Pioneer Seeds in the mid-90s but still continues the scientific reaseach at the Georgetown, ON location.
