If it's an actual core shop, they should have the molding equipment and experienced staff year round. Obviously they will wind down a bit, but it's not like they stop employing people. Usually the people who are in the shops during the summer season are the more experienced people anyway.
I'm not too familiar with Vancouver, but I'm sure there are some solid shops to go to there. If not, go to The Circle in Whistler, and they will take care of you.
