Well, as someone who used to live in Montréal I can tell you the old city is down on the relatively flat land by the river while the mountain (Mont Royal) in the middle is a park. I think you may be thinking of Québec, the old city sitting up on a hill.

This picture would make a beautiful poster. Is it me or the old city on high-grounds kind of evokes Montreal?

My bad. The image I had in mind is indeed of Québec which also really does not look like Montréal.
I gladly stand corrected 🙂
