Where to buy "Grimbergen" in Canada I've spent much time in Ottawa and Halifax, and have yet to find a consistent source of this nectar of the gods.
Locations Found:

Liquor Store in Whistler, BC

LCBO in Trainyards, Ottawa

Greek Restaurant in Downtown Ottawa

Brussels.

Anyone know where to find it?
This may not help you in Quebec, but if a product can be found in an LCBO somewhere in Ontario, you should be able to order that product at any LCBO in Ontario.
