Communidée is at 75 Sir George-Étienne Cartier in St-Henri.  See map below.

It is about a 10-minute walk from St-Henri metro.  If you are coming by car, finding parking on the street is usually pretty easy.

The building used to be an elementary school.  It is now a community centre called CRCS St-Zotique which houses some non-profit organizations during the day and an after-school program after 3pm.  There is a ramp outside, but no elevator inside.

The kitchen/classroom is in room 129.  To get there from the front door, go down the hall to the end, take a left, and find it down the hall on your left.

The gym doesn't have a room number, but is known at the mini-gym.  To get there from the front door, go down the hall and take your first left and go down some stairs.  At the bottom, go down a few more stairs on your left, and the gym is there on your right.
