Where can I buy bulk wild meat in Montreal?
From what I have gathered searching for an answer to this question, caribou, seal, and hare are the only actual wild game meats that can be purchased in Canada. Due to low demand, hare and seal may be very difficult to find, even in-season. All other "game meat" including "wild" boar, venison, bison, and rabbit is farm-raised and butchered. There is no farmed moose in North America. A recent  web article from the CBC, makes it seem like there may soon be a chance to find some trapped wild game on a limited number of Montreal menus, but not necessarily in stores anytime soon.  

In the US we have similar restrictions that may vary slightly state-to-state. The venison, bison, ostrich, turkey, pheasant, and quail available for purchase is all farm-raised and often imported from other countries. Wild boar from Texas, though, may be wild/feral and is trapped by permitted individuals and butchered at USDA approved facilities. USDA regulations require ante- and post-mortem inspection, meaning that the animals must be delivered to the slaughterhouse alive. These regulations limit the number of domestic wild boar available, even though we have a huge wild hog problem throughout the South, California, and Hawaii.

It seems that the only way to get actual game meat is to be a hunter or know a hunter who is willing to share the fruits of their labor.  In my experience, many hunters don't know what to do with large portions of the meat, and just grind almost everything but the loin and tenderloin into burger. It might be easier to get some of those tougher cuts from the front and hind limbs, especially if you offer to share some stew, a slow roasted shoulder, or some braised neck medallions.
