Hazardous household waste (HHW)

The collection of hazardous household waste is organized by the City of Montréal and takes place on Saturdays and Sundays, May 4 and 5 and September 14 and 15, 2024, between 9 a.m. and 5 p.m.

Hazardous household wastes are products that pose a risk to the environment and human health if they are not disposed of responsibly and safely.

Under no circumstances should hazardous household waste be disposed out into nature, into the sewers or included with household waste or recyclables.

To enable you to dispose of them safely, two City of Montréal temporary drop-off depots are set up in Pointe-Claire: one in the spring, the other in the fall. Collection takes place in the parking lot behind City Hall, at 451, boulevard Saint-Jean. See map
