It's hot. SNAP! recommends cooling off in the pool.

Montreal public pools are commonplace enough, the only trouble is finding them. 

Highly recommended is the one above the hospital, located on Avenue des Pins, just west of Rue University.  It's a bit of a trek up, but you can cool off right away in the water and the walk down after is ezaay.   Hotel de la Montagne  [1430 De La Montagne] has a  rooftop pool beside their bar.  There is also one just east of Parc de la Fontaine.  If you have the address of any other public outdoor pools, please let us know!
