Treated wood includes wood that has been stained, chemically treated, pressure treated, painted, and/or has screws, nails and other accessories embedded in the wood pieces.
Throw it out - Black Cart
Small quantities of treated wood can be put in the black cart. Wood pieces must be less than 15 cm (6") in diameter and shorter than 1.25 metres (4 ft.) so it can fit inside the cart. Please ensure the lid of the cart can close.
Too much wood in the black cart can be an issue for collection as it can damage the garbage truck.
Throw it out - City landfills
Larger residential quantities (such as from renovations or demolitions) can be taken to any City landfill. Charges will apply for disposal at City landfills.
