Drywall installation is a critical part of most construction and renovation projects — it turns bare framing into smooth, paint-ready walls and ceilings. But the cost can be hard to pin down because it depends on the drywall type, ceiling height, finish level, and how much taping and mudding the job requires.
This guide breaks down 2026 drywall installation costs in Toronto and the GTA, including materials, labour, finish levels, and the factors that move the number.
Drywall Installation Cost per Square Foot (2026)
In Toronto and the GTA, drywall installation runs $2.00–$4.50 per square foot for supply and install with a standard Level 4 finish. That covers materials, hanging, taping, mudding, and sanding to a paint-ready surface.
Note that quotes are usually based on the square footage of the walls and ceilings, not the floor area of the room.
| Component | Cost per Sq Ft |
|---|---|
| Materials (standard ½” board) | $0.50–$0.80 |
| Hanging labour | $0.85–$1.90 |
| Taping, mudding, finishing | $0.85–$3.50 |
| Fully installed (Level 4) | $2.00–$4.50 |
In the GTA, labour accounts for roughly 60–70% of the total, driven by high demand for skilled trades.
Drywall Cost by Type
The type of board you choose affects both material and installed cost:
| Drywall Type | Installed per Sq Ft | Best For |
|---|---|---|
| Standard ½” | $2.00–$3.00 | Bedrooms, living spaces |
| Moisture-resistant (“green board”) | $2.50–$4.00 | Bathrooms, basements, kitchens |
| Fire-rated (Type X) | $2.75–$4.50 | Garages, shared walls (code-required) |
| Soundproof / acoustic | $3.50–$5.00+ | Media rooms, shared walls, offices |
Fire-rated drywall is mandatory for garages and shared walls under the Ontario Building Code — it’s a code requirement, not an optional upgrade.
Project Cost Examples
| Project | Typical Installed Cost |
|---|---|
| Single room (12′ × 12′) | $600–$1,800 |
| Basement (800–1,000 sq ft) | $4,000–$12,000 |
| Full house (2,000 sq ft) | $8,000–$33,000+ |
What Drives Drywall Costs Up
- Ceiling height: 9- and 10-foot ceilings add 15–40% due to larger sheets, lifts, and scaffolding.
- Finish level: a Level 5 skim coat adds a full stage of labour over Level 4.
- Complexity: bulkheads, soffits, arches, and multiple corners or cutouts add labour (often 20–30%).
- Access: second-floor rooms with narrow stairways or downtown high-rises (elevator/parking logistics) cost more.
- Demolition: removing old drywall adds $0.50–$2.50 per square foot and bills separately.
Drywall Finish Levels
The Gypsum Association defines five finish levels. Most Toronto homes get a Level 4 (three coats, smooth) — the residential standard for flat and eggshell paint. A Level 5 (full skim coat) is used for high-gloss paint or walls under critical lighting, and costs more. Garages and utility spaces often use a lower level to save cost.
Best Drywall Type by Room
Different rooms call for different drywall. Matching the board to the room prevents moisture, fire, and sound problems later.
| Room | Recommended drywall | Why |
|---|---|---|
| Kitchen | Moisture-resistant near sinks; standard elsewhere | Handles humidity and splashes |
| Bathroom | Moisture- or mould-resistant; cement board behind tile and showers | Resists moisture and mould |
| Basement | Moisture-resistant, kept up off the slab | Guards against below-grade humidity |
| Living room and bedrooms | Standard 1/2-inch drywall | Cost-effective for dry areas |
| Garage | Fire-resistant (Type X), often required | Meets fire-separation requirements |
| Home theatre or media room | Soundproof or double-layer with damping | Controls sound transfer |
Always confirm local code — fire-rated drywall is mandatory in some assemblies, such as the garage-to-house separation.
Additional Costs to Budget
- Removing old drywall: $0.50–$2.50 per sq ft
- Insulation: $2–$4 per sq ft if added
- Soundproofing: $2–$5 per sq ft
- Painting/priming: $1–$3 per sq ft
- Permits (Toronto): typically $50–$150 for the drywall portion of a larger project
Why Professional Installation Matters
Drywall is a multi-step process — heavy lifting, precise cutting, hanging, taping, mudding, and sanding until the surface is glass-smooth. Poor hanging or finishing shows up as visible seams, sagging, nail pops, and cracks, and fixing it after paint means redoing the finish. Professional crews deliver flat, sound, paint-ready walls the first time.
