How much does it cost to drywall a basement in Toronto?

For a typical 800–1,000 sq ft GTA basement, expect $7,000–$14,000 for board and finishing once you account for the ceiling and all the walls (real surface area is usually 2–2.5x the floor area). Add insulation, vapour barrier, and bulkheads around ductwork and you're closer to the top of that range. Soundproofing the ceiling under a busy main floor pushes it higher.

Do I need a permit to drywall a room in the GTA, and what does it cost?

Replacing or finishing drywall on its own does not require a building permit anywhere in the GTA — it's considered finishing work. You only need a permit when the project involves moving walls, framing, new plumbing or electrical, or finishing a basement as new living space, in which case the permit covers the whole scope and runs roughly $180–$600+ depending on the city (Toronto, Mississauga, and Vaughan all price differently). A reputable contractor pulls this for you.

What's the cheapest way to finish drywall and still look good?

Stick to a Level 3 or solid Level 4 finish and paint with a flat or matte finish — flatter paint hides minor imperfections that gloss would expose, so you avoid paying for a Level 5 skim coat. Keeping the existing layout (no moved walls) and doing demo yourself where it's safe also trims labour. Where it does not pay to cut corners is taping: a cheap finisher leaves seams and nail pops you'll stare at for years.

How much does it cost to patch a hole or repair water-damaged drywall?

A small hole or single patch is usually a $300–$900 flat call-out in the GTA — most of that is the trip, setup, and the wait between mud coats, not the materials. Water-damaged areas cost more because the source has to be fixed first and any mould dealt with; budget $800–$2,500 for a damaged ceiling section once you include matching texture and repainting the affected area.

Drywall & Plaster Cost in Toronto & the GTA (2026)

Drywall is one of those jobs where the per-sheet material cost is cheap and the labour is everything — taping and finishing is a skilled trade, and in the GTA that skill isn't cheap. Most homeowners here pay $2.50–$4.50 per square foot of wall and ceiling area to hang and finish (board, screws, tape, three coats of mud, sanded and ready for primer), with the spread driven mostly by ceiling height, finish level, and how clean the access is. The numbers below are real 2026 Greater Toronto pricing — Toronto, Mississauga, Vaughan, Brampton, and the surrounding cities all sit in a similar band, a notch above the Canadian average because of GTA labour rates and disposal fees.

What it costs

Pricing tiers in the GTA.

Budget / patch & repair

$2.50–$3.00 per sq ft (or $300–$900 per repair)

Standard 1/2" board, Level 3 finish, flat 8-9 ft walls, easy access. Covers small patches, single-room board-and-tape, or closing up after another trade. Repairs are usually priced as a flat call-out rather than by the foot.

Best for: Landlords, pre-paint touch-ups, garage/basement utility spaces, and anyone painting over the wall in a heavier finish or texture

Mid-range / standard reno

$3.00–$3.75 per sq ft

The workhorse tier for a typical Toronto reno: Level 4 finish ready for flat or eggshell paint, standard 9 ft ceilings, normal corners and a couple of bulkheads. Includes 1/2" board on walls and 5/8" on ceilings.

Best for: Whole-room renos, finished basements, additions, and most main-floor living spaces

High-end / Level 5 & specialty board

$3.75–$4.50+ per sq ft

Level 5 skim coat (a full thin layer of mud over the entire surface) for glossy paint and raking light, plus mould/moisture-resistant board in wet areas, soundproof (Type X / QuietRock-style) assemblies, and high or vaulted ceilings needing scaffold.

Best for: Custom homes, feature walls under pot lights, home theatres, ensuites, and anywhere a perfectly smooth wall under bright light is non-negotiable

Plaster / heritage restoration

$8–$15+ per sq ft

Traditional 2-3 coat plaster or matching/repairing original lath-and-plaster in older Toronto homes (the Annex, Cabbagetown, Leslieville). Far more labour-intensive than modern drywall and a specialist skill.

Best for: Heritage properties, plaster cornice/medallion repair, and owners restoring rather than replacing original walls

Where the money goes

Cost breakdown by component.

Drywall board (material): $18–$50 per 4x8 sheet depending on type; roughly 10–18% of a hang-and-finish job
Hanging labour: $0.40–$0.70 per sq ft — screwing board to studs and ceiling
Taping, mudding & finishing labour: $1.50–$2.75 per sq ft — the skilled portion, 3 coats plus sanding; more for Level 5
Tape, mud, screws, corner bead (consumables): $0.20–$0.40 per sq ft
Demolition & disposal (if applicable): $1.50–$3.00 per sq ft removed + $400–$700 GTA bin/disposal fee
Permit (only if part of structural/layout work): $180–$600+ depending on city and project scope — drywall alone needs no permit
Scaffold / lift rental for high ceilings: $150–$400 for the duration of the job

What moves the price

The factors that drive your quote.

Finish level (Level 3 vs 4 vs 5)
Jumping from a standard Level 4 to a full Level 5 skim coat adds roughly $0.75–$1.25/sq ft — it's the single biggest driver inside the hang-and-finish range because it's almost pure extra labour and mud.
Ceiling height & access
9 ft ceilings, vaulted areas, or stairwells that need scaffold or stilts add 15–30% to labour. Tight basement access and hauling board down a narrow staircase can add $0.25–$0.50/sq ft.
Board type / material grade
Standard board is ~$18–$24 a sheet. Mould-resistant runs $30–$40, and 5/8" Type X fire/sound board $35–$50. Specialty soundproof panels can push material 2–3x on the affected walls.
Demolition & disposal of old material
Tearing out old plaster or water-damaged board adds $1.50–$3.00/sq ft, and GTA dumpster/disposal fees run $400–$700 — old plaster is heavy and bins fill fast.
Insulation, vapour barrier & soundproofing behind the board
If walls are open, adding batt insulation and poly vapour barrier (required by Ontario code on exterior walls) adds $1.50–$3.50/sq ft before any board goes up.
Structural or moisture issues found behind the wall
Rot, mould remediation, or a sagging joist discovered at tear-out is the classic budget-buster — remediation and framing repairs commonly add $1,500–$6,000+ depending on what's behind there.
