The Metro is an underground transportation system of light rail that links most of downtown Montréal. We never had to wait more than 5 minutes for a connection. The system was completed about 25 years ago but continues to grow. Most of the time the trains were full. I was impressed. They did something right.
We were two blocks away from the Place D'Armes Metro station.
The system is nowhere as big as Paris but very convenient for getting around.
