Window Replacement Quotes in the GTA: We Read 25 Price Pages

Ask three GTA window companies what a window costs and you get three numbers you cannot compare. We read the price pages of 25 window companies serving the GTA on August 26, 2026. Twenty publish at least one real figure. Only nine say whether it is supply only or installed, and eight publish at least one figure with no scope label at all. None publishes a minimum order. Ontario buyers who finished whole-home jobs report about $1,273 to $2,462 per rough opening (the hole in the wall one or more window units fill), installed. Make the seller write down one number: the price per rough opening, installed, with HST stated.

What 25 GTA window companies publish

Every site faced the same tests.

The five that publish no figure are Nordik, Brock, HTR, Casa Bella and Consumer's Choice. Nordik says why: "We don't promote fake sales with inflated prices." Consumer's Choice publishes a promise instead: "Our quote is valid for 30 days after it is issued."

No site sets out a smallest job either. A Toronto homeowner with one failed sealed unit, the factory-sealed double or triple pane glass sandwich, could not get a company to quote at all.

What a published number actually means

The clearest supply-only label is also the sharpest trap. Window Mart's Toronto table sits under the heading "Replacement Windows Cost. Supply Only!" and opens at "Picture & Fixed windows From $279". Higher up, the same page puts the typical Toronto range at "$400 – $2100 per window", unlabelled. The $279 is glass and a frame on a truck.

Vinyl Light is the only one of the 25 that publishes the conversion. Its notes column reads "Window from $350 + installation from $200", beside a casement at "From $550" under the heading "Starting Installed Price".

Home Depot Canada prints the same numbers under both labels on one page. A casement is $900 to $1,200 in a table headed "Price Range Per Window Installation", and $900 to $1,200 again in one footnoted "Window prices depicted in chart above exclude installation".

Torwin gives the lower number for the bigger job. Its table prices a 24 by 36 inch slider at $600 to $800, footnoted "*Installation & taxes extra". Its body text prices the same slider at "$500 to $700" for "the product and installation".

EcoTech disagrees with itself by 2.75 times on one page and labels neither figure: a bay or bow window is $5,500 to $11,000 in its table and "Typically $1,500 – $4,000" in its FAQ.

Retrofit means the new window goes into the old frame. Brick to brick, also called full frame, means the frame and all comes out, down to the brick.

The four jobs that settle it

Total Home runs three scope rules on one page: a calculator noted "Installation costs ... are not included", a material table with no scope note, and a whole-house table footnoted "All prices include professional installation and basic trim work". It publishes about twenty finished jobs; four are below.

Two of them hold the number nobody advertises. $13,899 divided by 19 retrofit openings is $731 each. $6,200 divided by 5 brick to brick openings is $1,240 each. That is 70 per cent more per opening, same company, same year. No price table in this audit shows the split.

Buyers land well above the advertised floors. One r/PersonalFinanceCanada poster paid $14,000 in 2023 for 11 brick to brick openings, taxes in and before rebate ($14,000 divided by 11 = $1,273 an opening). A Toronto quote for 13 openings came to $26,000 ($26,000 divided by 13 = $2,000 each). A third paid $32,000 for 13 openings before rebate ($32,000 divided by 13 = $2,462).

What the discounts were worth

Seven of the 25 run a percentage off or deferred payment banner. The fine print runs from thin to absent. Custom Contracting's sticky banner reads "65% Off Install + 0% Interest for 6 Months", above a lead form headed "0% Interest for 12 Months!", with no end date and no lender. EcoTech advertises "Save Up To 50%", with fine print reading, in full, "*Offers end soon. Certain conditions apply." Brock advertises "up to 50% OFF" with no date, though its own disclaimer says expiry dates are "generally listed in the upper right-hand corner".

Two offers had expired before we read them. Total Home still shows "Ends August 31, 2025 Free exterior colour on windows", a year past its own expiry. HTR's financing card is headed "No Paying Until 2025" while its body says "don't pay ... until 2024".

A promotion can also turn out not to cover your job. A 2024 Google review of a Vaughan windows and doors company describes a call about its "50% off installation" offer, answered with "your project would meet the requirements". The visit was for a front door, not windows. Only when the buyer asked did the rep say the promo was windows only, and offer 15 per cent off the door instead. Get an offer's scope in writing first.

A 2019 review of the same company shows another tactic. A written price of 45k became 28k if the buyer paid that day, a $17,000 drop in one visit ($45,000 minus $28,000 = $17,000). The Competition Bureau names it: "Be wary of strangers pressuring you by offering deals for a limited time."

The rebate, and what it actually pays

Ontario's Home Renovation Savings Program is the only province-wide window rebate live in August 2026. The headline is easy to advertise: $100 per rough opening. The rules are not.

• Per opening, not per window. The rebate "is offered per rough opening, as opposed to per number of windows or doors installed within the opening". Inside a project with at least three window openings, a three-window bay adds $100, not $300. On its own it pays nothing: the program's Example #4 prices three windows in one opening at $0.
• Three openings, minimum. Replacing "only one (1) or two (2) windows ... will not count as a single Qualified Measure or qualify for a Rebate". Three openings "would ... qualify for a Rebate of $300".
• Windows alone never qualify. With doors, skylights and sliding doors they "count as one (1) single Qualified Measure", and you must "install at least two (2) Qualified Measures". The second is insulation or air sealing, which is why attic insulation turns up in a window quote.
• Audit first, and pay for it. You must "complete a Pre-Audit" before any work; work "completed prior to the Pre-Audit will not be eligible". You front both assessments, get $600 back after two upgrades, and $500 more for three or more assessed on or after January 5, 2026.
• Glass alone is out: "replacements of only the glass, sash or door without a frame are not eligible".
• The ceiling is two numbers. Up to $5,000 for a home space-heated with Enbridge natural gas. Up to $10,000 for one heated with electricity, oil, propane or wood on the IESO-controlled grid.

Run it on that Toronto quote: 13 openings x $100 = $1,300, or 5 per cent of the $26,000 job ($1,300 divided by $26,000). The Post-Audit is due within 180 days of the Pre-Audit or by December 31, 2026, whichever is first, and must be in the administrators' tracking system by November 30, 2026.

Window Installation Toronto is the one site of the 25 that states them. Its FAQ reads: "You need a minimum of three windows, and windows must be bundled with at least one other eligible upgrade ..."

Six of the 25 still advertise a closed federal program. Natural Resources Canada says December 31, 2025 "was the final day for applicants to upload their documents" for the Canada Greener Homes Grant. Eurostar still lists the "Canada Greener Homes Loan: Up to $40,000 at 0% interest", and EcoTech lists it as "currently available". The loan page at Natural Resources Canada says "This program is closed" and "New loan applications cannot be approved". Magic alone names the closures. Its page warns: "If a contractor quotes a price that assumes one of these programs will offset your replacement cost, they haven't checked recently."

Nothing requires triple glazing either. ENERGY STAR version 5.0 took effect on January 1, 2020. It sets one national bar: a U-factor of 1.22 W/m2K or an Energy Rating of 34. Air leakage must be at or below 1.5 L/s/m2.

What protects you at the kitchen table

Windows are not on Ontario's restricted door-to-door list. That list is closed: furnaces, air conditioners, air cleaners and purifiers, water heaters, water treatment devices, purifiers, filters and softeners, duct cleaning services, and anything doing those jobs. Consumer Protection Ontario says the rest plainly: "Products and services not listed on this page can still be sold door-to-door". The window pitch at your kitchen table is legal. The furnace pitch next door has not been, since March 1, 2018. The remedy that voids a restricted-product contract does not reach windows.

The general rule covers you instead: "You always have a cooling-off period when you sign a contract in your home." You can cancel for any reason within 10 days of getting a written copy. For most contracts, the company then has 15 days to return your money. Send the cancellation by email or registered mail, so the date is provable. If the seller misrepresented the goods or services, you have up to one year.

How to get a quote you can compare

• Name the scope in writing: retrofit or brick to brick, 70 per cent apart in one company's jobs.
• Ask for a price per rough opening, not per window. The rebate is paid that way.
• Get HST written down. Only six of the 25 say how HST is treated. On a $15,000 job the 13 per cent is $1,950 ($15,000 x 0.13).
• Ask what the number covers: removal, exterior capping, insulation, cleanup and a labour warranty, or only the window unit (Window Land).
• Do the rebate arithmetic first, both assessments included.
• Never sign on the visit.
