Where or what store can I buy a FLASK in Montreal, Quebec?

I don't know about Montreal, but here in BC you can usually find a flask in a gift shop, or a gift section in a department store. Try men's gift stores, cigar stores, key making kiosks, any novelty type things. I always seem to run into them every year Christmas shopping. Go to any average sized mall and look at these types of places and you should find one.
