I lived there for several years, a long time ago.

Let me tell you that after the first week of the winter, it doesn't feel like a winter wonderland anymore. It's constant slush and grey.

That said, Montreal is an amazing city to visit, or even to live if you can find a job. It's affordable - yes, that's because the economy has been depressed for the last 40 years, but that means there are all sorts of fascinating people who couldn't afford a modern city otherwise. It's got great nightlife, world-class restaurants, culture, nice parks.
