For the area, our July 2026 dataset puts polished concrete – typical residential installed rate, Toronto runs $5.50–$7.00 per sq ft (CAD) (Toronto Epoxy Pros) and new concrete pour + polish (slab supplied and finished) runs $10–$25+ per sq ft (CAD) (Armour Guard).

| Item | Typical range | Unit | Source |
|---|---|---|---|
| Basement epoxy floor, installed (Ontario)Ontario, not Toronto specifically. Canadian Concrete Surfaces notes basement moisture requires specialised primer and moisture-mitigation systems that push the cost up. | $3–$7 | per sq ft (CAD) | Canadian Concrete Surfaces |
| Polished concrete – typical residential installed rate, TorontoToronto Epoxy says each project is unique and that the cost per square foot can fall as the area rises. This is a residential installed rate, narrower than Armour Guard's $3-$12 span because it covers one company's standard job. | $5.50–$7.00 | per sq ft (CAD) | Toronto Epoxy Pros |
| Epoxy garage floor – full-flake/chip system, installedMonarch's summary box figure; its body text gives $5-$10 for the same flake or chip system. Flake adds slip resistance over a solid colour. | $6–$10 | per sq ft (CAD) | Monarch Epoxy Coatings |
| Polyaspartic one-day flake system, installedMonarch says polyaspartic generally falls in this range and rates it highly for the Toronto climate. A polyurea and polyaspartic hybrid runs $9-$14 and can last over 20 years. | $7–$12 | per sq ft (CAD) | Monarch Epoxy Coatings |
| New concrete pour + polish (slab supplied and finished)Open-ended at the top: Armour Guard writes $10-$25+ where a new concrete pour is required, against $3-$12 for polishing a slab that already exists. | $10–$25+ | per sq ft (CAD) | Armour Guard |
| Polished concrete – mid-sheen satin finish (up to 800 grit)Armour Guard's middle tier between a basic grind and seal ($3-$6) and a high-gloss finish ($8-$15). Existing slab only. | $6–$10 | per sq ft (CAD) | Armour Guard |
Every polished concrete contractor here is ranked by the same public formula: a review-volume-weighted Google rating, what the company states on its own site, and the state of its record. The median company here carries 30 Google reviews. That keeps the list of 5 honest, and no spot is ever paid for. Read our full methodology.
In Oshawa, this is year-round work, since it happens indoors or below grade rather than on open ground. Good local polished concrete contractors book up in peak weeks, so request quotes with some lead time.
Before hiring, request a live WSIB clearance and a liability certificate, and verify the dates. ConcreteFinder surfaces verification signals on every Oshawa profile, yet the actual insurance paperwork should be confirmed with the polished concrete contractor first.
An honest Oshawa quote names the prep, mix and thickness, reinforcement, finish, joints and disposal, then deposit, stages and warranty. If a bid is a single lump sum with no breakdown, ask for the itemized version before you sign.
Nobody buys a higher Oshawa spot. Positions come from a published score across the 5 polished concrete contractors on this page: reviews weighed by volume, the company's own stated details, and its website, phone and photos. In Oshawa, 100% of rated companies clear 4.8★, so small gaps matter.
Free estimates are the norm for local polished concrete contractors, usually after a short site visit. ConcreteFinder does not book them for you; it ranks the companies and publishes how to reach each one.
