OK. I understand that "bagels" is not a restaurant. But, if you go to Montreal, you must eat fresh bagels.  Seriously, if you have not had baked-that-morning-fresh bagels you have not lived.

There are several fresh bagel shops in Montreal.  Two of my favorite are:

St. Viateur -- located at 263 St-Viateur O., they are open 24/7

Fairmont -- located at 74 Avenue Fairmount O
