Air Canada has at least 8 direct flight a day from Logan to Montreal (1hr 12 minutes). The Direct Air Canada Fare from Boston-Montreal is ridiculously high ($800-1500 RT). Air Canada is the only Airline in Boston that offers direct flight to Montreal. You better off going to EWR/LGA/JFK for flights to Montreal. I have seen base fares as low as $150.00 RT to Montreal w/Toronto Connection in EWR/LGA/JFK.
