What's the best way to dispose of old pressure-treated deck wood in Metro Vancouver without getting fined?

Old pressure-treated lumber requires special disposal in Metro Vancouver because it contains chemical preservatives that are classified as hazardous waste. You cannot put it in regular garbage, burn it, or take it to standard recycling depots — doing so can result in fines and environmental violations.

Metro Vancouver Waste Disposal Options

The Transfer Stations operated by Metro Vancouver accept pressure-treated lumber as construction and demolition waste, but you'll pay disposal fees. The Vancouver South Transfer Station (8400 River Road), Burnaby Waste-to-Energy Facility (7888 Canada Way), and Coquitlam Transfer Station (2755 United Boulevard) all accept treated lumber. Expect to pay $140-160 per tonne, and you'll need to separate the PT lumber from other materials. Bring identification and be prepared to declare what type of treated lumber you're disposing of.

Most municipal landfills and eco-centres do not accept pressure-treated lumber because of the chemical preservatives (ACQ, CCA, or older arsenic-based treatments). The City of Vancouver's landfill and transfer stations will turn you away if you try to dispose of PT lumber with regular construction debris. Same with Richmond, Burnaby, and Surrey municipal facilities.

Private Disposal Services

Several private waste management companies in Metro Vancouver specialize in construction debris and will handle pressure-treated lumber properly. Waste Management, GFL Environmental, and Emterra Group all offer construction waste bins that accept treated lumber, but you'll pay premium rates — typically $400-600 for a 10-yard bin including pickup. This is often the most convenient option for whole-deck demolitions where you're dealing with several hundred square feet of old decking, joists, and posts.

What NOT to Do

Never burn pressure-treated lumber — the chemical preservatives release toxic fumes that are dangerous to inhale and illegal to burn in Metro Vancouver. The fine for illegal burning can exceed $1,000. Never put PT lumber in regular household garbage — it will be rejected at the curb or at transfer stations. Never try to pass it off as regular construction lumber at recycling depots — the green tint and end tags usually make treated lumber obvious, and you could face disposal violations.

Cost-Saving Tips

If you're hiring a contractor for deck demolition, confirm that proper PT lumber disposal is included in their quote. Professional deck builders have established relationships with waste management companies and often get better disposal rates than homeowners. If you're DIY demolishing, consider renting a construction waste bin specifically rated for treated lumber rather than making multiple trips to transfer stations — the convenience often justifies the cost difference.

Identifying Pressure-Treated Lumber

Look for the green tint (from copper-based preservatives), end tags or stamps indicating the treatment type and manufacturer, and incised surfaces (small slits that help preservative penetration). Lumber from decks built before 2004 may contain CCA (chromated copper arsenate) with arsenic — this requires even more careful handling and disposal.
