Household Hazardous Waste


You'll find the City of Thunder Bay's Household Hazardous Waste Depot at the Solid Waste & Recycling Facility (landfill) on Mapleward Road. It is open daily during regular landfill hours (see our Solid Waste & Recycling Facility webpage for more details).

The depot only accepts special residential waste such as:

  • paint
  • insecticides
  • drain cleaner
  • spot remover
  • household batteries
  • spent fluorescent tubes and CFLs
  • oven cleaner
  • used motor oil and oil filters (limit of two 5-gallon containers of used oil at any one time)
  • empty propane tanks, etc.
  • electronic waste (see our Electronic Waste webpage) 

If the product you wish to dispose of is marked DANGER or POISON, this indicates that it is toxic, corrosive or extremely flammable. WARNING or CAUTION indicates that the product is slightly toxic. Disposal of all of these products poses a threat to the environment if not handled correctly, so we encourage you to drop off such materials at the Depot.

Please bring hazardous waste in its original container, or label all products you bring to the Depot. Never mix hazardous wastes.

Identifying Hazardous Products

Hazardous Household WasteIt's not always easy to identify hazardous products. Consumers often rely on product labels for information, but labels may not list all ingredients. To determine if a product is potentially hazardous, see if it bears any of the following symbols or signal words such as Danger, Warning, Poison, Caution, Caustic, Irritant or Volatile. Products labelled Danger are the most hazardous, and products labelled Caution are the least hazardous.
