Tour in Montreal before flight home

I will be disembarking in Montreal from HAL Maasdam early August. My flight back to the states is at 2:00 pm. Any reasonable tours that I can book ahead of time that will pick me up at the port, take me on a tour and then drop me off at the airport?

The cruise has an excursion that includes airport drop off but a flight has to leave 2:45 pm or later so I can't book it.

I did see one tour on line but it was $675 (before taxes) for 4 hrs. Ouch!!

Any ideas or suggestions are appreciated.

Thanks in advance.

There's lots to see in Montreal. Could you not fly home a day or two later?

what kind of tours you are looking for?

I found this one. It looks like they might pick you up from the pier. They have one that leaves at 9:00 am. Has good reviews.
