As someone living in an Ontario wine growing region, I can assure you that we bring in plenty of migrant workers every year.

They're still paid more than California labour. And in any case, apart from not needing irrigation, growing conditions here are way more difficult than California. (At least for now). And equipment and input costs also way higher.

(I grow about a 1/2 acre of grapes here in Ontario)
