canada?

Can anyone explain why the tomatoes I bought in the local dominks the other day say product of canada? I mean I didn't really expect locally grown mind you, but if you can't get tomatoes grown here this time of year where are they coming from in canada? I was more than a little scared, but since I already paid for them I thought i'd best eat them. not great I sure you. I mean if we can going to manipulate the way things are grown can't we at least do it closer to home, and say save on the cost of gas. i'm just saying it makes more sense.
oh sorry about the typing i"m writing from my phone on the train! just cause I can.
