We're leaving on a cruise in August, but flying back from Montreal. If we park at the terminal, is there a shuttle back to our car from the airport??

Parking at the terminal is $25 a day. Parking at several of the hotels in the area is usually about $17 a day. If flying back, you are better off taking a taxi. Also , as a bonus, the taxi can drop you directly in front of the terminal.

You best bet would be a taxi. Rhe fare from the airport tonthe cruise terminal is about 25 dollars.
