I had several cams of paint ranging from old to extremely old taking up room in my storage area so I decided to go online and discover how I can recycle them. On the city of Toronto website I found a few options.
Household Hazardous Waste (HHW) can be disposed of by:
Note: HHW (both drop-off & Toxic Taxi) are for residential hazardous waste, not from industrial or commercial institutions.
in person drop-off at a HHW depot
drop off HHW at your local Community Environment Day event, or
by scheduling a Toxic Taxi pick-up (conditions apply)
There is no fee for drop-off or pick-up of HHW items.
Now I know what to do and can get rid of them all.
