Composite Deck Prices in Canada: National Average Overview
The average cost of composite decking materials in Canada varies significantly depending on the product’s quality, brand reputation, material composition, and availability in different provinces. Composite decking is typically priced per square foot, which makes it easier for homeowners and contractors to estimate total material costs for a deck project. However, this also means that even small variations in unit pricing can add up quickly over larger deck areas.
As of 2025, the national average cost for composite decking boards in Canada falls within the following ranges:
| Composite Deck Type | Price per Square Foot (CAD) |
|---|---|
| Entry-level | $4.00 – $6.00 |
| Mid-range | $6.50 – $8.50 |
| Premium | $9.00 – $12.00+ |
Entry-level composite decking typically includes basic wood-plastic composites (WPC) without advanced surface treatments or color depth. These options are great for budget-conscious projects and may still offer good durability and resistance to rot and splintering. Mid-range products usually provide a better balance between aesthetics and performance, with co-extruded capping layers, deeper wood grain textures, and more color options. Premium composite decking tends to include high-end features such as ultra-dense core materials, enhanced UV resistance, superior slip resistance, and sometimes hidden fastener compatibility.
To provide a clearer picture, let’s break down material cost estimates for a standard 300-square-foot deck:
Entry-level boards: With unit costs between $4.00 and $6.00 per sq.ft, total material expenses could range from $1,200 to $1,800 CAD.
Mid-range boards: At $6.50 to $8.50 per sq.ft, the budget would range between $1,950 and $2,550 CAD.
Premium boards: For high-end materials priced at $9.00 or more per sq.ft, costs may exceed $2,700 and potentially go beyond $3,600, especially with specialty finishes.
It’s important to note that these prices cover only the decking boards themselves. They do not include the cost of the substructure (e.g., joists and beams), railing systems, screws or hidden fasteners, stairs, skirting, or labor. Additionally, regional variations in shipping and local taxes (GST/HST) can further affect final pricing, especially in provinces like British Columbia or remote regions like Northern Ontario. While composite decking offers long-term savings through reduced maintenance, understanding this initial cost structure is essential for proper budgeting.
This base price discussion lays the foundation for evaluating total composite decking cost per square foot in Canada, which includes both materials and installation — a topic we’ll explore in upcoming sections.
Key Factors Affecting Composite Decking Cost in Canada
a. Material Quality
Composite decking includes a variety of product types such as wood-plastic composites (WPC), capped composites, and full-PVC boards. Higher-quality capped composites or PVC boards tend to resist fading, moisture, and staining better than their lower-end counterparts, but they also cost more.
b. Brand and Manufacturer
Popular brands like Trex, TimberTech, Fiberon, and Azek are generally more expensive due to their brand reputation, warranties, and design innovations. However, several Canadian or less-known brands may offer similar quality at a slightly reduced price.
c. Texture, Color, and Finish
More realistic woodgrain patterns and premium finishes drive up prices. Darker colors, custom tones, and anti-slip textures often cost extra. If aesthetic is a high priority, expect to spend more.
d. Add-ons and Accessories
Accessories such as hidden fasteners, fascia boards, end caps, and skirting can significantly increase the overall cost.
e. Environmental Certifications and Features
Decking with certifications like FSC, LEED eligibility, or Class A fire ratings often carry a price premium. Consumers may be willing to pay more for environmentally responsible or safer materials.
Composite Decking Installation Costs in Canada
In addition to material prices, installation costs can significantly affect the total composite decking cost per square foot in Canada. Prices vary based on region, deck size, complexity, and whether the installation is done professionally or DIY.
Average composite decking installation cost (including labor and substructure):
| Province/Region | Installation Cost (per sq. ft.) |
| British Columbia | $10.00 – $16.00 |
| Ontario | $9.00 – $14.00 |
| Alberta | $8.50 – $13.50 |
| Quebec | $9.00 – $13.00 |
| Atlantic Provinces | $10.00 – $15.00 |
For a 300 sq. ft. deck, installation alone can cost between $2,700 and $4,800.
DIY vs. Professional Installation
DIY projects can reduce installation costs significantly but require time, tools, and technical knowledge.
Professional installation ensures compliance with building codes, safety, and aesthetics.
Hidden or Additional Costs to Be Aware Of
Composite decking projects often come with costs beyond just the boards and basic labor. Here are the most common hidden costs:
Substructure materials: Joists, beams, and footings can add $3 – $6/sq. ft.
Old deck removal: If replacing an old deck, expect $500 – $1,500 in demolition and disposal costs.
Railing and stairs: Railings can cost $40 – $100 per linear foot. Stairs also increase costs.
Permits and inspections: Depending on your municipality, permit fees range from $150 – $500.
Delivery and logistics: In remote areas, delivery may add $200 – $600 or more.
These can turn an advertised $6/sq. ft. board into a $15+/sq. ft. total cost.
Cost Comparison: Composite Decking vs Other Deck Materials in Canada
One of the most common questions homeowners face when planning a new deck project is whether to choose traditional wood or invest in composite decking. While the initial cost is often the deciding factor for budget-conscious consumers, a comprehensive cost comparison over a 10-year period reveals a more accurate picture of total ownership cost. When evaluating composite decking price per square foot in Canada, it’s crucial to weigh both the upfront investment and long-term maintenance savings.
Here’s a breakdown of typical costs by material type:
| Material Type | Initial Cost/sq. ft. | 10-Year Maintenance Cost | Total 10-Year Cost (Estimate) |
|---|---|---|---|
| Pressure-treated wood | $2.00 – $3.00 | $1,000 – $2,000 | ~$3,500 |
| Cedar | $4.00 – $5.00 | $800 – $1,500 | ~$4,500 |
| Composite Decking | $6.00 – $12.00 | Minimal (~$200) | ~$4,500 – $6,800 |
Pressure-treated wood remains the most affordable material upfront. For a 300-square-foot deck, the initial investment may only be around $600 – $900. However, this type of wood requires ongoing sealing, staining, or painting to protect it from moisture, UV exposure, and insect damage. Over 10 years, these recurring maintenance tasks can add up to $1,000 or more — not to mention the labor and time involved.
Cedar offers a more aesthetic and natural wood appearance, but like pressure-treated wood, it is not maintenance-free. While it’s more durable and naturally resistant to decay, it still requires regular oiling or staining to maintain its color and structural integrity. Cedar decking also tends to be priced higher than treated lumber, often ranging from $4.00 to $5.00 per square foot, with long-term maintenance adding significant additional costs.
In contrast, composite decking has a higher upfront cost, with materials ranging from $6.00 to $12.00 per square foot, depending on the brand, finish, and grade. However, one of the most compelling reasons many Canadian homeowners are switching to composite decking is its extremely low maintenance requirements. No annual staining, sanding, or sealing is needed — just an occasional rinse with water and mild soap. Over a 10-year period, total maintenance costs may remain as low as $200 or less, primarily for cleaning products or minor touch-ups.
When comparing the total cost of ownership, composite decking becomes increasingly attractive, especially for those planning to stay in their home long-term. Not only does it offer savings on maintenance, but it also retains its visual appeal better over time, resists fading, warping, and splintering, and adds value to the property. For many, the convenience and long-term durability justify the higher initial price.
Therefore, although the price of composite decking in Canada may seem steep at first glance, the math changes when you consider the 10-year timeline. It provides better value for homeowners looking for a low-maintenance, long-lasting solution, making it a smart investment despite the higher starting price per square foot.
How to Estimate the Total Price of a Composite Deck Project
Here’s a sample formula to estimate your project:
Total Price = (Deck Area x Material Price) + Installation + Accessories + Extras
Example: 300 sq. ft. Deck
Composite boards: 300 sq. ft. x $8 = $2,400
Installation: 300 sq. ft. x $11 = $3,300
Accessories & fasteners: ~$600
Permit, delivery, etc.: ~$500
Estimated Total: $6,800
Using a spreadsheet or online calculator can help plan your budget in more detail.
