How much does it cost to epoxy a 2 car garage in Toronto?

Take the floor at 400 to 450 square feet and multiply. A solid-colour coat at the $4 to $9 per square foot the four applicators here publish lands roughly $1,600 to $4,050 on a 450 sq ft bay. The whole-job figures those same firms print sit inside that: GLI Toronto quotes $2,400 to $4,800 for a 400 sq ft two-car garage, Canadian Concrete Surfaces $1,600 to $3,200, Monarch $2,660 to $5,000 for standard epoxy, and ProEpoxy $1,800 to $2,800 for a 400 to 500 sq ft double.

Why do the quotes I am getting vary by thousands of dollars?

Because prep is not a fixed quantity and nobody can see it until the floor is ground. SurfacePro puts surface prep at about 30 percent of a garage job, base coat and flakes at 50 percent, top coat at 20 percent. Two firms looking at the same slab can disagree on whether it needs grinding at $1 to $3 per square foot on top, a $300 to $600 strip of an old coating, or a moisture barrier at $2.00 to $4.50 per square foot. Tick those boxes in the calculator and the spread stops being a mystery.

Is flake worth the extra money over a plain colour?

It costs less extra than most people expect. ProEpoxy prices decorative flake at $0.50 to $1.00 per square foot over solid, which is $200 to $450 on a double garage. Metallic is the real jump: ProEpoxy puts it at $2 to $4 per square foot over solid, and Armour Guard prices decorative systems generally at $5 to $12 per square foot on top of the base. Flake also hides tyre marks and salt residue, which matters more here than the look does.

Does the calculator include HST?

No. Every rate behind it is quoted before tax by the applicator that published it, so the range you see is pre-tax. Add 13 percent for Ontario HST on the whole job, materials and labour together. A $3,000 estimate is about $3,390 on the invoice.

What is the cheapest honest way to coat a GTA garage floor?

A solid-colour epoxy on a sound slab that needs no extra prep. Monarch puts standard solid epoxy at $4 to $6 per square foot installed, the lowest published figure of the four sources here, and ProEpoxy quotes $1,200 to $1,800 for a whole single-car bay at 200 to 250 square feet. Below that you are into a DIY kit, which is a different product with a different lifespan.

Should the price change because my garage is bigger?

Yes, downward per square foot. ProEpoxy publishes a falling rate as bays are added: $5 to $7 per square foot on a single, $4.50 to $6 on a double, $4 to $6 on a triple. Mobilisation, grinding setup and the minimum crew day are the same whatever the size, so they spread thinner over a larger floor. If a quote for a triple bay carries the same per-foot rate as a single, ask why.

Epoxy Garage Floor Cost Calculator for the Greater Toronto Area

Last updated: August 26, 2026By EpoxyFloorIndex Research Team

Multiply your floor area by the installed rate for the system you want, then add the prep the slab actually needs. On a 400 square foot two-car garage a solid-colour epoxy works out at roughly $1,600 to $3,600 before tax, and a metallic finish at $3,200 to $4,800. The calculator does that arithmetic against ranges published by 8 named GTA applicators, and shows which name is behind each line.

Where these rates come from

EpoxyFloorIndex read 8 Toronto and Ontario coating firms that publish their own pricing, and recorded each range against the company that states it (August 2026). The calculator takes the lowest low and the highest high for a system and uses that as the band. It does not average them. Where Monarch says $4 to $6 for solid-colour epoxy and GLI Ontario says $5 to $9, the answer you get is $4 to $9, because both firms are quoting real GTA work and the honest range is the one that contains both.

Three things the calculator cannot know, and a real quote will. First, how the slab behaves under a grinder: a floor that dusts or delaminates changes the prep line after the work has started. Second, whether the concrete is releasing moisture, which is the single most common cause of a coating peeling in this climate and the reason the moisture-barrier line exists. Third, access. A detached garage with a narrow side path costs more to run equipment into than an attached one you can back a van up to, and no published rate sheet prices that.

Winter matters too. Coatings have a minimum application temperature, so an unheated GTA garage is a spring-to-autumn job unless the applicator brings heat, and heating is billable time.

Whole-job prices these same firms publish

A per-square-foot band is only half a sanity check. These are complete garage jobs as quoted by the firm named beside each one, so you can see whether the estimate above lands where real quoted work lands.

CAD, before 13% HST. Armour Guard's $1,200 to $10,000 is the widest because it is deliberately the full spread of what a homeowner might choose on the same 400 square feet, from a thin single coat to a full decorative system.
