Like OJFord mentions, it is a bit far from amenities despite the straight line distance to them not being great because it's built on an island in the river and you have to cross the bridge to get to the downtown area.

But more importantly for me, my usual life is not in Montreal. I love Montreal but moving there would require quite a few sacrifices in personal relationships that I don't feel like making. And government services in Quebec are also worse than in Ontario (where I am now).
