Oftentimes—on potatoes, for example--you go to the supermarket today and with bulk potatoes it will say “Canada or U.S”. Now, you have to ask which ones are Canadian, of course. But that's not going to happen. It just doesn't happen.
The question was asked on onions. Onions are generally bulked on the shelf like that as well, although we don't have much more than three onion producers in B.C. anymore.
So the issue is that you can't get the supermarkets to do what should be done in the way you would want it done.
