Hazardous household waste

Last updated April 4, 2022

Cans of paint, cleaning products, used oil, used batteries and dead lightbulbs, etc. Find out how to safely dispose of toxic, inflammable, corrosive or explosive products.

Hazardous household waste (HHW) must never be thrown away outdoors, in household waste, in the sewer, or put in  the recycling bin with recyclable materials. They are polluting and dangerous.

Drop-off sites

You can bring hazardous household waste (HHW) to 3 types of locations:

Travelling collections

These temporary drop-off sites are set up in the spring, summer and fall in several boroughs and neighbouring municipalities. All residents of the island of Montréal can go to one of our collection sites, based on the applicable schedules, to safely drop off HHW.

Ecocentres

Is there no travelling collection in your neighbourhood? Visit an ecocentre to drop off your HHW.

  • To protect the environment against potential sources of contamination.
  • To give you an alternative to storing products in your home that could potentially be dangerous to your health.
