Hazardous Waste Disposal days

The Town hosts disposal days throughout the year to provide residents with a safe and convenient way to get rid of hazardous waste. Events are held at the Municipal Operations Centre (MOC) located at 408 James Street South (enter off South Service Road) from 8:00 am to 12:00 pm.

All materials must be sealed and in their original containers with labels. Materials in leaking, damaged, corroded and unlabeled containers will not be accepted. 

Materials should be transported in the rear of vehicles (trunk, truck bed, etc.), and contained in boxes for safe transport and unloading. Vehicles with materials in the back or front seat will be re-directed to a separate area of the parking lot where they can be moved to the trunk or tailgate. Residents are asked to remain in their vehicles at all times as materials will be unloaded by trained staff.

Please note that the hazardous waste depot that was located at the St. Marys Landfill has now been closed. Hazardous material will no longer be accepted at the landfill.
