Thanks for the correction. I was going off of what I was told by several farmers, without verifying it independently.
Interestingly, however, I haven’t heard of any rapeseed grown, in recent history, up in Canada, at least not in my neck of the woods.
It is still called “rape” between farmers, because when we’re talking farmer-to-farmer, we know what we’re talking about.
When non-farmers are about, we’ll use the latin family name, “brassica.”
It is partly PC-ism, but saying “Wow, I got a bumper crop of rape!” in mixed, non-farming company causes a whole lot of people to whip their heads around, and that’s the fault of the non-farmers.
Rape (and other brassicas) are grown for more than just their seed, btw — some brassicas make excellent quick-growing graze for cattle, with excellent feed value.
