I just returned from Montreal which I absolutely adore.  Great people, architecture & food (foie gras, poutine.. need I say more?)  Here are a couple of the highlights:
The Greenest Building in North America (Cirque du Soleil HQ):
Grand Bibliotheque du Montreal:
The Biosphere:
Schulich School of Music:
Favorite Restaurants:

1.) Le Cartet:  A great breakfast place 2.) Lemeac:  The best for classical French 3.) Le Trois Petits Bouchons: Amazing rustic French fare + hot waiters
