The event will run from 8:00 a.m. to 12:00 p.m. and St. Marys and Perth South residents can dispose of their hazardous waste at the Municipal Operations Centre (MOC) located at 408 James Street South (enter off South Service Road). 

Items that will be accepted at the disposal event include:

  • Acids, aerosol cans (full), antifreeze
  • Bases, batteries, bleach
  • Compact Fluorescent Light Bulbs (CFLs), fluorescent tubes
  • Fertilizers, fuels, garden and pool chemicals
  • Household cleaners, motor oil, paints, pesticides

All materials must be sealed and in their original containers with labels. 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 MHSW depot that was located at the St. Marys Landfill has now been closed, and MHSW material will no longer be received at the landfill.
