How much does a deck cost in Canada?

Composite decking in Canada in 2026 costs $60–$120 per square foot installed. Material-only is $14–$28 per sq ft. The wide range reflects the difference between entry-tier composite (Fiberon GoodLife, Eva-Last Infinity IS — around $60–$80 installed) and premium capped composite (Trex Transcend, Eva-Last Apex PLUS, Deckorators Voyage — $85–$120 installed). Capped polymer / PVC sits a tier above composite at $90–$160 installed.

Upfront, a composite deck costs roughly 2x what a pressure-treated deck does ($60–$120 vs. $30–$50 per sq ft installed). Over 20 years, however, composite typically wins on total cost of ownership because pressure-treated wood requires stain or seal every 2–3 years and surface board replacement within 15 years. Once 6–8 refinishes and partial rebuild are factored in, the 20-year carrying costs end up within 20% of each other — and composite still looks new on year 19.

All four major composite brands TUDS stocks sit in roughly the same per-sq-ft range, but tier matters more than brand. Entry tier (Fiberon GoodLife, Eva-Last Infinity IS): $60–$80 installed. Premium tier (Trex Transcend, Eva-Last Apex PLUS, Deckorators Voyage): $85–$120 installed. Luxury / capped PVC tier (Trex Signature, Eva-Last Pioneer, Deckorators Vault): $110–$160 installed. Where each brand leans differs — see Eva-Last, Trex, Fiberon, and Deckorators hubs for tier-by-tier breakdowns.

Material cost is roughly the same in major Canadian cities, but labour differs. Saskatoon / Regina: $50–$75/hr typical contractor rate. Calgary / Edmonton: $60–$90/hr. Toronto / Vancouver: $80–$120/hr. The same 320 sq ft mid-tier composite deck that costs $25,000–$30,000 installed in Saskatchewan can run $35,000–$45,000+ in the GTA. Permits also vary — typical Saskatchewan municipal residential-deck permit is $100–$500; Ontario and BC municipalities often run $400–$1,000 [VERIFY current municipal fee schedules].

Labour is roughly 40–60% of installed cost for most Canadian residential decks. A homeowner with framing experience self-installing a 320 sq ft composite deck can save $10,000–$20,000 vs. a contractor build, but the realistic savings number is closer to 30–45% once you factor in tool rentals (auger, mitre saw, trailer), waste material (count on 10% extra boards), and the time cost of getting it right. DIY savings are largest on pressure-treated (40–55%) and smallest on tropical hardwood (20–35%, because hardwood requires pre-drilling and specialty fasteners).

The five biggest budget-busters: (1) Railing — $80–$200 per linear foot. A 60 ft railing run on a typical deck adds $5,000–$12,000. (2) Stairs — $100–$300 per step including framing and decking. A 4-step stairs adds $400–$1,200. (3) Footings — Prairie frost depth is 1.2m / 4 ft, so each pier costs $150–$400 installed; a 320 sq ft deck typically needs 6–10 piers. (4) Permits — $100–$500 in Saskatchewan, more in some provinces. (5) Lighting + electrical — $40–$150 per fixture installed, plus a separate electrical permit.

Residential deck permit fees in Saskatchewan vary by municipality and project size, typically $100–$500. Saskatoon: residential decks under 10 sq m generally don't require a permit; over that, fees scale with construction value (around $100–$300 for typical backyard projects). Regina: similar threshold, fees scale with value. Smaller municipalities: flat $100–$200 permits are common. All decks attached to a house require a building permit regardless of size in most Saskatchewan municipalities. [VERIFY current City of Saskatoon and City of Regina fee schedules at time of build.]

On the Prairies, deck footings have to extend below frost depth — 1.2 metres (4 ft) in Saskatchewan and most of Alberta and Manitoba. That's roughly twice the depth required in coastal BC or southern Ontario. Each concrete pier or helical pile costs $150–$400 installed in Saskatchewan. A 320 sq ft deck typically needs 6–10 piers, so footings alone add $1,000–$4,000 to total project cost. Helical piles are increasingly popular in our climate because they install in a day and don't require curing time.

Railing is one of the costliest line items per linear foot. In 2026 Canada: Pressure-treated wood railing: $40–$80 per linear ft installed. Aluminum railing (e.g. Fortress AL13 Home, Regal Ideas): $80–$180 per linear ft. Glass-panel + aluminum-post railing: $150–$300+ per linear ft. Cable railing: $120–$220 per linear ft. A 60-ft railing run on a typical 320 sq ft deck adds $5,000–$18,000 depending on system. See Regal Ideas and Fortress AL13 Home hubs for system-by-system costs.

Stairs add $100–$300 per step including framing, stringers, treads, risers, and railing. A typical residential deck with a 4-step stairs to grade runs $400–$1,200. Wide stairs with multiple stringers, or stairs that turn / land partway, scale up quickly — a 6-step + landing setup often adds $2,000–$3,000. Composite stair-tread board costs about 30% more than equivalent decking board because of the manufactured nosing.

Low-voltage LED deck lighting runs $40–$150 per fixture installed on a typical Saskatchewan deck. A 320 sq ft deck with stair-tread lights, post-cap lights, and a few accent fixtures usually budgets $1,500–$4,000 all-in including the transformer and a separate electrical permit (most Saskatchewan municipalities require one for any line-voltage work; low-voltage from a plug-in transformer is usually exempt). Smart-controlled systems (app + dimmer) add 20–30% to fixture cost.
