Q: we are a family with a baby of two years old.
A: There isn't really much to occupy a two-year-old on the island of Laval itself. You could visit the Cosmodome located just off the Laurentian Autoroute (highway 15)...it's a space museum. There is also great shopping to be done at Carrefour Laval and at several outlet malls in the same area. However, most attractions are either in Montreal (which is a 15 minute drive) or further north, where you can do tons of outdoor activities in the Laurentians. It would be worth it to take a day trip up to Mont Tremblant, where you can do walking, hiking, biking, take a gondola tour, etc. Have fun!
