Hazardous Household Waste: Important Safety Reminder for All Residents
With July 1 approaching, the City of Dorval would like to remind all residents that it is strictly prohibited to dispose of prohibited hazardous materials through regular curbside collections, including garbage, recycling, or organic waste. This directive is in place to ensure the safety of sanitation workers and the community as a whole.
Why is this reminder important?
Every year, dangerous incidents occur in Dorval and across Québec as a result of improper disposal of prohibited hazardous materials. For instance, a forgotten battery inside a toy or the presence of a leaking chemical container in a garbage bag can cause a fire or explosion in a collection truck. Such incidents place workers at serious risk, damage municipal equipment, disrupt services for residents, and result in unnecessary operational costs.
Examples of materials that must never be placed in regular pickups:
- Compressed gases (e.g., propane or butane tanks)
- Batteries (alkaline, lithium-ion, rechargeable, vehicle, etc.)
- Paints, varnishes, thinners, solvents, glues, used oils
- Acids and bases (e.g., industrial or domestic cleaning products)
- Explosive or flammable materials
- Pool maintenance chemicals
- Pressurized aerosol containers
- Ammunition, fireworks, or contaminated sharp objects
Consequences of improper disposal include:
- Fire or explosion inside collection vehicles
- Serious injury to workers or nearby residents
- Interruptions to citywide waste collection services
- Fines or penalties in accordance with municipal regulations
Next official HHW drop-off event:
The next hazardous household waste drop-off in Dorval will take place on the following date:
Date: Saturday, September 6, 2025
Time: 9 a.m. to 5 p.m.
Location: Ballantyne Park parking lot (520 Bouchard Boulevard)
Residents may safely and responsibly dispose of various hazardous products free of charge during this event. Propane tanks—empty or full—will be accepted. However, any container that is open, leaking, or larger than 20 litres will be refused.
The HHW collection is strictly for household use. Businesses, institutions, and industries must retain the services of a certified hazardous waste contractor at their own expense.
Year-round disposal options also available:
In addition to municipal events, residents can:
- Visit ecocentres
- Drop off accepted materials (such as batteries, oil, and paint) at participating retailers
- Use the free “Ça va où?” app from Recyc-Québec to determine how and where to dispose of specific items properly
Please note:
Responsible waste management starts at home. By sorting hazardous materials properly, using the appropriate drop-off services, and staying informed, residents contribute directly to the safety of sanitation teams, the protection of city infrastructure, and the well-being of the community.
