How to Install a Pressure-Treated Wood Deck in Toronto

Complete step-by-step guide for installing pressure-treated wood decking in Toronto, Ontario. Includes climate-specific tips for Toronto's great lakes weather conditions.

Step 1: Check Permits and Plan Your Deck

In Toronto, verify permit requirements with local building department. Major cities typically require permits for decks over 2 feet high. Measure your space, plan deck layout, and determine pressure-treated wood quantity needed. Account for frost depth requirements in Toronto (typically 1.2m minimum).

Step 2: Install Footings and Foundation

Dig footings to required depth for Toronto (1.2m or deeper to prevent frost heave). Standard concrete footings work well. Ensure footings are level and properly spaced for pressure-treated wood installation requirements.

Step 3: Build Deck Frame and Joists

Install ledger board (if attaching to house), beams, and joists according to Pressure-Treated Wood manufacturer specifications. Standard 16-inch joist spacing for wood decking.

Step 4: Install and Seal Pressure-Treated Wood Boards

Install pressure-treated wood boards with proper spacing (3-5mm) for expansion. Seal with quality deck sealer within 2 weeks of installation. Pre-drill screw holes to prevent splitting.

Step 5: Install Railings and Finishing Touches

If deck is elevated, install railings meeting Toronto building code (typically 36-42 inches high). Wood railings should match deck material and finish. Add stairs if needed, ensuring proper rise and run dimensions. Complete final inspections as required by Toronto regulations.

Step 6: Protect Your Deck for Toronto Weather

For Toronto's harsh winters: seal all gaps before winter, ensure proper drainage to prevent ice buildup, and remove snow carefully to avoid surface damage. Apply winter-grade sealer in fall.
