If you love Indian food, there is an Indian food fair tomorrow (Saturday 28th April) night from five until ten pm at Lucien Page School (8200 St-Laurent corner Jarry).
They have the fair every year, and we went a couple of years ago so I can speak from personal experience when I say that the food is delicious and varied (although all or almost all vegetarian) and very different from anything you get in the average Montreal Indian restaurant.
Most booths sell their wares for one or two dollars per portion.
