In this blog post, Hosung WPC will diving deep into the details. We’ll look at average prices across provinces, key cost factors, materials, smart tips to help you build your dream deck without breaking the bank, and long-term considerations that help determine value beyond initial spending.
Average Deck Building Cost in Canada (2025 Overview)
As of 2025, the average cost to build a deck in Canada ranges between $40 to $100 per square foot. This includes materials and professional installation. Your total cost will depend on the size, design, materials, and location.
Sample Cost Estimates:
- 100 sq. ft: $4,000 – $10,000
- 200 sq. ft: $8,000 – $20,000
- 300 sq. ft: $12,000 – $30,000
It’s important to note that urban areas like Toronto, Vancouver, and Calgary typically have higher labour and permit costs compared to rural regions.
Provincial Comparison:
ProvinceEstimated Range (per sq. ft)
Ontario $60 – $90
BC $65 – $95
Alberta $50 – $80
Quebec $45 – $75
These figures are averages and can vary based on material prices, contractor demand, and local bylaw requirements.
What Affects the Cost to Build a Deck In Canada?
1. Deck Size and Layout
The size of your deck is the most obvious cost factor. A larger deck requires more materials and more labour. However, complexity also plays a significant role. A simple rectangular platform is far more affordable than a multi-level deck with built-in features, curved edges, or attached structures.
Adding corners, cutouts, levels, or integrated seating can all increase labour time and materials. Additionally, taller decks, especially those built on sloped lots, will require extra structural supports, which can add thousands to the final price.
2. Decking Material
Different materials come with different price tags, maintenance requirements, and lifespans.
- Pressure-treated wood: Most economical; around $3–$7/sq. ft. Readily available and DIY-friendly.
- Cedar: Aesthetic and durable; around $5–$9/sq. ft. Offers natural resistance to decay.
- Composite decking: Popular for its low maintenance and modern appeal; $8–$15/sq. ft.
- PVC or aluminum: Long-lasting and premium; $10–$20/sq. ft. Often used in high-end projects.
In colder regions, composite and PVC are gaining popularity due to their weather resistance and low maintenance requirements.
3. Labour
Labour costs vary by region but generally fall between $25 to $45 per square foot. In cities with high demand or where tradespeople are in short supply, expect to pay at the higher end of that range.
Hiring licensed professionals might cost more upfront but ensures quality workmanship, code compliance, and warranty-backed construction.
4. Site Preparation and Permits
Not all lots are created equal. Uneven or rocky terrain will increase the cost due to additional excavation or foundation work. Also, many municipalities require permits for deck construction, especially if the deck is elevated or exceeds a certain size.
- Permit fees: $150 – $1,200 depending on city and complexity.
- Site leveling and grading: $500 – $3,000.
- Post footings and concrete: $1,000 – $3,000 depending on number and depth.
Neglecting to acquire permits can lead to fines and even mandatory deck removal.
Additional Features That Impact Price
Beyond the basic structure, many homeowners choose to add features for functionality or aesthetics. Here are a few extras and their typical price ranges:
- Railings: $30–$80 per linear foot (glass, metal, or wood)
- Stairs: $200–$350 per step
- Privacy Screens: $500–$2,000
- Pergolas or Roof Covers: $1,500–$5,000+
- Lighting Systems: $300–$1,500
- Built-in Seating or Planters: $800–$2,000
- Outdoor Kitchens or Firepits: $3,000–$10,000
If your goal is to create an entertainment oasis, these add-ons can turn a simple platform into a luxurious retreat—but with a cost to match.
Regional Deck Building Costs Across Canada
Ontario
Known for high property and labour costs, Ontario—especially Toronto—has some of the highest deck building rates in the country. Many homeowners choose composite decking due to weather extremes. The GTA may see costs as high as $120/sq. ft. for premium builds.
British Columbia
Rainy and damp conditions mean many opt for PVC or composite decking. Labour costs are high, and building code compliance is strict. Vancouver’s hilly terrain may also increase site preparation costs significantly.
Alberta
Deck construction is more affordable but must be timed well due to a shorter outdoor building season. Pressure-treated wood and cedar are commonly used. Calgary and Edmonton also require engineering reports for some elevated decks.
Quebec
Generally lower labour costs, especially in rural areas. Many projects use pressure-treated wood for affordability. Montreal has more stringent regulations and higher permit fees.
Atlantic Canada
Nova Scotia and New Brunswick see moderate material costs but lower labour fees. Weatherproofing is critical due to salty air and coastal exposure.
Smart Ways to Save Money on Your Deck Project
Looking to lower the cost to build a deck in Canada without sacrificing quality? Consider these tips:
- Use a basic design – Skip multi-tier levels and complex shapes.
- DIY what you can – Handle staining, painting, or even simple installations.
- Get multiple quotes – Compare offers from at least 3 licensed contractors.
- Opt for off-season construction – Builders often offer discounts in spring or fall.
- Choose budget-friendly materials – Use composite only for the surface and pressure-treated for framing.
- Buy in bulk – Purchase all materials at once to qualify for supplier discounts.
- Reuse and recycle – Repurpose materials where possible.
- Bundle projects – Combine your deck with other landscaping or renovation tasks to negotiate better rates.
Even small savings in design and planning can add up to thousands saved on the final bill.
Long-Term Considerations
Don’t just focus on upfront costs. A cheaper wood deck may need staining every year and replacement in 10–15 years, while a composite deck may last 25+ years with minimal maintenance.
Annual Maintenance Costs:
- Wood Deck: $300–$800/year
- Composite/PVC Deck: $50–$200/year (mostly cleaning)
Also consider resale value: a quality deck adds visual appeal and usable space, which can help attract buyers and improve appraisal values.
Return on Investment (ROI):
- Basic wood deck: 60–70%
- Composite or upscale deck: 70–80%
A deck built with future-proofing in mind—such as weather-resistant materials and smart lighting—can become a true asset to your property.
Conclusion
The cost to build a deck in Canada is influenced by many factors—from the size and materials to location and features. Whether you’re on a tight budget or aiming for luxury, there’s a deck solution that fits your vision.
