Canada Transportation

Really nice city with lots of nightlife activities during summer (Festival Juste pour rire, Local Gay Pride, etc).
Corner of St-Catherine Street and St-Denis street is the place to be (really hot and fun).
People is really friendly and from all classes.
Visit Park Mont-Royal, Biodome, Jardin Botanique (if you like flowers), Stade Olympique has nothing special but a great view but a bit expensive...) and if you like attractions go to La Ronde (Ile Saint-Helene).
Finish at night by a dinner near the Vieux-Port (old Montréal) or by a hockey game at the Molson Center ;)

The new Canada Line Skytrain is now running, so you can take that to get into downtown Vancouver from the airport in less than half an hour.

Never call a cab in Vancover, it will never come. My friends n me waited an hour at Stanley Park, we decided to walk back to town under the cold snow, which took us another 1hour.

Serious sightseeing in Niagara Falls happens at the Horeshoe Falls on the Canadian side... feels like you can touch the water as it goes over the cliff, and great waterside dining at the Table Rock restaurant (where I worked for a summer as a kid). Parking is a problem (especially on sunny days) so you're best to park up top and take the cable car down to the falls.

The zodiac whalewatching tours are great here !
