Absolutely perfect! Easy to navigate (only three lines), clean, not too crowded, and a much better way to get to your destination than handling many construction detours and rush hour traffic.

I spent three full days in Montreal and visited every major attraction using the Metro. It is reasonably priced, fast, safe, clean and crisscrossed the entire city. It does not go to the airport but..

Bought a pas for metro at airport. Used it to take the bus 747 to gare Centrale. This is where you notice the Canadian humor: bus 747 as in Boeing 747. From there you can reach the entire city with me
