Bring old paint to a Household Hazardous Waste (HHW) depot. Most Canadian cities run regular collection depots or have special curbside HHW collection days. To find out dates, times and locations, go to your city’s HHW website or call your municipal public-works department.
Divide and conquer
Hardened latex paint is not hazardous if disposed of properly. Quickly harden leftover latex paint by pouring absorbent kitty litter, paint hardener or clay-based absorbent into the can. The container can be recycled, and you can safely throw out the solidified paint.
Rona will take your leftovers and make them into paint they can sell.
Lighter colours can be taken to a paint retailer to be re-tinted for another project.
One person’s trash is another’s treasure. Donate unwanted but usable oil and latex paint at your local HHW Reuse Centre, which recycles leftovers for free.
