Household waste

Many household, automotive and gardening products are even more harmful to the environment if improperly discarded. Westmount hosts a special collection day each spring and fall when residents may bring products for safe disposal. Hazardous or toxic products must not go in the regular garbage nor down the drain, but should instead be brought to the Hazardous Waste Collections:

For more information on disposal of hazardous waste or any other material, contact Public Works.


Spring: Saturday, April 25, 2020, 9 a.m. to 5 p.m.
