Crab seems to be food non grata in MTL. Sure you got the queen crab legs and the king crab, but an honest blue crab meal is a rare sight indeed. It used to be on every chinatown menu, now even there, somewhat rare (it may be on the menu, but its not in stock).
Theres a thread about foods that haunt you ('cause you can't get it anymore) and I always think about a restaurant on Parc called Crab a Folie. Spider crab or dungeness or blue or a gargantuan australian crab - all on the menu and all-u-can eat. They dumped it in a pile on the table. OMG, PARADISE!
If you want a boil, seems ya gotta do it yerself. Gitterdone!
