Household hazardous waste is never a curbside item. It goes to a municipal drop-off, and most regions run dedicated depots for exactly this. In Peel Region — the same region where the recalled companies are based — a full or partially full aerosol can is classified as household hazardous waste and must be taken to a Community Recycling Centre, where drop-off is free. Curbside set-out is not an option.
The empty-versus-not-empty distinction is the one most people miss. An empty aerosol can is often blue-bin material. A can with contents still inside is not — it is hazardous waste, full stop. A recalled salt-remover can almost certainly has propellant and product left in it, which puts it squarely in the hazardous-waste category no matter how ordinary it looks. One more rule closes off a tempting shortcut: under the Canada Consumer Product Safety Act, recalled products cannot be sold, redistributed, or even given away in Canada. Handing the can to a neighbour who "might use it" is not a legal or a safe way out.
To find your local instructions, search your municipality or region's name with "household hazardous waste" and look for the depot hours and accepted-items list. If you are unsure whether a specific site takes aerosols, call before you drive over. Health Canada has flagged disposal as the required action on other products too — it recently advised consumers to dispose of an uncertified IQYEF alarm after the seller declined to run a recall.
Holding the Can Safely Until Drop-Off
Depots are not open every day, so most people need to store the can for a stretch first. The Region of Waterloo's handling guidance is a clean checklist: keep the product in its original container so it can be identified, keep the lid or cap tightly sealed, avoid mixing it with other materials, and store it in a safe, dry, secure spot out of reach of children and pets until you can drop it off.
