What does slab and garage pad work run per square foot in Toronto?
According to 2AZ Group (GTA subcontractor rates, early 2026), garage slab, standard 20x20, subcontractor-installed runs $5,000–$8,000 per project in the GTA, while garage slab, contractor-installed (published slab rate) runs $26–$31 per sq ft installed (Compare Paving Contractors (Canada)). Add 13% HST to any quote. The table below breaks down 8 line items, each with its own named source.
| Item | Typical range | Unit | Source |
|---|---|---|---|
| Garage slab, standard 20x20, subcontractor-installed2AZ Group's subcontractor rate table, installed prices including materials and labour. It says the wide range reflects straightforward pours on easy sites against complex work with access issues, slopes or engineering requirements. The per-square-foot figure this guide used to show was not published by 2AZ; it was this total divided by 400 sq ft. | $5,000–$8,000 | per project | 2AZ Group (GTA subcontractor rates, early 2026) |
| Garage slab, contractor-installed (published slab rate)Compare Paving Contractors' own published slab rate. The same page prices an insulated-formwork slab lower, from $15 per sq ft, and notes a garage slab averages about 6 inches thick. It stresses that contractors, not materials, drive most of the variation, so compare several quotes. | $26–$31 | per sq ft installed | Compare Paving Contractors (Canada) |
| Basic broom-finish concrete pad, Ontario benchmark (5–7" with A-gravel base)An Ontario average, not a Toronto figure. The Art of Concrete says a 100 sq ft project runs $2,500 to $5,000 because the per-square-foot price is higher on small jobs, and that a no-frills broom-finished pad typically starts around $20 per square foot. | $15–$30 | per sq ft installed | The Art of Concrete (Kitchener, ON, Jan 2025) |
| Shed pad, 4–5" slab incl. excavation, compacted gravel and meshNice Guy Concrete says this includes excavation, gravel base, reinforcement and concrete installation, and that the figure depends on size, thickness and site conditions. | $15–$25(typ. $1,800–$3,000 for a 10'×12' (120 sq ft) pad) | per sq ft installed | Nice Guy Concrete (Milton/Oakville/Mississauga) |
| Basement/garage interior floor pour only (4" basement at 32 MPa; 6" garage)Both figures are open-ended floors, not ranges: Strong Basements writes starts at $10+ for a 4-inch basement slab and $15+ for a 6-inch garage slab. Pour only, with removal, gravel, insulation and reinforcement all priced separately. | $10–$15 | per sq ft | Strong Basements (Toronto/Etobicoke) |
| Existing floor removal + excavation (before re-pour)Open-ended floors. Strong Basements writes starts at $14+ for a standard 7-inch basement excavation and $20+ for a 10-inch garage depth, the garage being dearer because it means demolishing a 6-inch slab heavily reinforced with rebar. The $10 floor this guide used to show is not on their page. | $14–$20 | per sq ft | Strong Basements (Toronto/Etobicoke) |
| Gravel bedding base, 5" compactedA flat rate, not a range: Strong Basements charges $5 per sq ft for a 5-inch gravel bed in both basements and garages. | $5–$5 | per sq ft | Strong Basements (Toronto/Etobicoke) |
| Rigid foam under-slab insulation add-on, 2"Open-ended: Strong Basements lists $4+ per sq ft for 2-inch R10 rigid foam, and lists slab insulation as not applicable in a garage. The $6 ceiling this guide used to show is not on their page; thicker sheets run to R20 at 4 inches and cost more. | $4–$4+ | per sq ft | Strong Basements (Toronto/Etobicoke) |
How does ConcreteFinder rank concrete slab contractors?
ConcreteFinder scores every company out of 100. Reviews are 45 of that, weighing review volume alongside the star rating so consistent, high-volume reputations rise to the top. The remaining 47 count what a company states on its own website, each line quoted from the page it was read off, and the details on the record: a website that answers, photographs, a phone, posted hours. Never paid placement.
GTA-wide, 83% of the rated concrete slab contractors already sit at 4.8★ or better, so read a two-place gap on this list as a real one. Placement cannot be bought. Read how the order is calculated.

Questions to ask your contractor
- What granular base depth and compaction go under the slab? What base prep costs
- What slab thickness and reinforcement, rebar or mesh, for this load?
- Is a vapour barrier included for an interior or heated floor?
- Where do the control joints go, and will you thicken the edges?
- Does this pad need a permit, and will you handle it?
Frequently asked questions
What is the going rate for slab and garage pad work across Toronto and the GTA?
According to 2AZ Group (GTA subcontractor rates, early 2026), garage slab, standard 20x20, subcontractor-installed runs $5,000–$8,000 per project, and garage slab, contractor-installed (published slab rate) runs $26–$31 per sq ft installed (Compare Paving Contractors (Canada)). Quotes are pre-tax, so add 13% HST on top. The garage pads & slabs cost guide here breaks the job into line items and names the source behind each one.
How do I tell a solid GTA concrete slab contractor from a cheap pour?
Compare at least three written, itemized quotes rather than defaulting to the cheapest. ConcreteFinder ranks 10 concrete slab contractors at an average 4.87★ Google rating; the middle of that field sits on 36 reviews. Start with the shortlist above, then ask each crew for the address of a pour it finished at least two winters ago and go and look at the joints.
Which months are the right ones to schedule slab and garage pad work in Toronto?
The GTA slab and garage pad work season runs Apr–Nov, because fresh concrete needs above-freezing temperatures to cure. Reputable companies book several weeks ahead in peak months, so request quotes early; shoulder-season pours in spring or fall often win better pricing.
Do I need a permit, and is HST included in slab and garage pad work quotes?
Add 13% HST to any quote, since concrete work is taxable in Ontario and most posted prices exclude it. Permit needs depend on scope: a like-for-like driveway or slab repour rarely needs one, but widening a driveway, altering the curb cut or boulevard, and any structural foundation or underpinning work require municipal approval and often an engineer, which a reputable contractor arranges. See ConcreteFinder's garage pads & slabs cost guide for the Ontario rules.
Will a contractor move up this list by paying ConcreteFinder?
No, and there is no product to buy that would change it. The order is a Google rating pulled toward the field average by review count, plus small boosts for a website, a phone number and photographs on file. Money is not one of the inputs. GTA-wide, 83% of the rated concrete slab contractors already sit at 4.8★ or better. In a field that tight, a couple of positions is a real difference, not noise.
