What Is Composite Decking?
Composite decking is an engineered outdoor flooring material made from a blend of:
- Wood fibers or wood flour
- Recycled plastics or polymer resins
- Additives for UV resistance, color stability, and strength
Unlike natural wood, composite boards are designed to resist rot, warping, insect damage, and moisture absorption.
Key Benefits
- Low maintenance (no staining or sealing required)
- Long lifespan (often 20–30+ years)
- Resistant to Canadian weather conditions
- Splinter-free surface
- Consistent appearance and color options
These benefits significantly influence the composite decking price in Canada compared to traditional lumber.
Composite Decking Price Canada Overview
The cost of composite decking in Canada varies widely depending on material quality, design complexity, and installation requirements.
Average Price Range (Materials Only)
- Low-end composite decking: $4 – $7 per sq ft
- Mid-range composite decking: $7 – $12 per sq ft
- Premium composite decking: $12 – $20+ per sq ft
Installed Cost Range
- Basic installation: $25 – $40 per sq ft
- Mid-range installation: $40 – $65 per sq ft
- High-end custom builds: $65 – $100+ per sq ft
These numbers reflect typical composite decking price Canada trends across residential projects.
Factors That Affect Composite Decking Price in Canada
Several important factors determine how much you will pay.
1. Material Quality
Higher-quality composite boards usually contain:
- More durable polymer blends
- Better UV protection
- Improved scratch resistance
- More realistic wood textures
Lower-cost options may fade faster or have less structural integrity.
2. Board Type (Hollow vs Solid)
- Hollow boards:
- Lower cost
- Lightweight
- Easier installation
- Less durable in heavy-load applications
- Solid boards:
- Higher strength
- Better for commercial or high-traffic areas
- More expensive
This difference alone can significantly change composite decking price Canada estimates.
3. Deck Size and Layout Complexity
Larger or more complex decks cost more due to:
- Increased material usage
- More labor hours
- Structural reinforcement needs
- Waste from cutting and fitting
Simple rectangular decks are significantly cheaper per square foot than multi-level or curved designs.
4. Installation Labor Costs
Labor is a major cost factor in Canada.
Typical labor rates:
- $15 – $40 per sq ft depending on region and complexity
Urban areas such as Toronto, Vancouver, and Calgary often have higher labor rates than rural regions.
5. Substructure Requirements
The deck frame (joists, beams, footings) is often overlooked but essential.
Costs may include:
- Pressure-treated lumber framing
- Steel framing (higher cost, longer lifespan)
- Concrete footings
- Hardware and fasteners
Substructure can add 30–50% to total project cost.
6. Railings and Accessories
Additional features significantly affect pricing:
- Railings: $40 – $150 per linear foot
- Stairs: $100 – $300 per step
- Lighting systems: $50 – $200 per fixture
- Skirting and fascia boards: extra finishing costs
7. Geographic Location in Canada
Composite decking price Canada varies by region:
- British Columbia:Higher due to labor and demand
- Ontario:Moderate to high pricing
- Alberta:Slightly lower labor costs
- Atlantic provinces:Material transport may increase costs

- Materials: $6,000 – $14,000
- Installation: $16,000 – $40,000
- Total: $22,000 – $54,000
Composite Decking vs Wood Decking Cost in Canada
While composite decking has a higher upfront cost, long-term savings are significant.
Wood Decking Costs
- Initial cost: $15 – $35 per sq ft installed
- Maintenance: $500 – $2,000 every few years
- Lifespan: 10–15 years
Composite Decking Costs
- Initial cost: $25 – $100 per sq ft installed
- Maintenance: minimal
- Lifespan: 20–30+ years
Long-Term Value Comparison
Composite decking often becomes more cost-effective after 7–10 years due to reduced maintenance and replacement costs.
Maintenance Cost Comparison
One of the strongest advantages of composite decking is reduced upkeep.
Wood Maintenance Costs
- Staining every 2–3 years
