How Much Do New Windows Cost in Ontario? (2026)
Straight answer: about $800–$1500 per opening installed, which puts a typical home around $8,000–$15,000 before the rebate. But "per opening" hides a lot — here's what moves the price, and a calculator to get your own number.

What new windows cost in Ontario — after the rebate
Cost figures are Ontario market estimates (editable above), not a quote — actual pricing depends on size, frame material, and glazing. The $100/opening rebate is the HRS program figure. For an exact price, get quotes from installers.
How the window rebate works →What you're actually paying for
The per-opening price bundles the window unit, removal of the old one, installation labour, and finishing. Three factors swing it most: size (a small bathroom window costs a fraction of a large picture window), frame material (vinyl cheapest; fibreglass and wood premium), and glazing (triple-pane over double adds cost but cuts heat loss). Upper-floor and hard-access openings add labour.
Cost by project size (before rebate)
Estimates only — adjust the per-opening figure in the calculator to match your quotes. Then subtract the $100/opening rebate.
How to bring the cost down
Get three quotes (prices for identical windows vary a lot), claim the HRS rebate, and if you're doing other work, bundle upgrades to lift your total rebate. ENERGY STAR® certification is required for the rebate anyway — and it's what cuts your heating bills long-term.

How much does it cost to replace windows in Ontario?
Installed replacement windows typically run $800–$1500 per opening in Ontario, so a typical 8–10 window home is roughly $8,000–$15,000 before rebate. Size, frame material, and glazing drive the range.
What makes windows more expensive?
Larger openings, premium frame materials (fibreglass and wood over vinyl), triple- vs double-pane glazing, and custom shapes. Labour and removal of old units also add up, especially on upper floors.
Does the rebate lower the cost much?
The HRS rebate is $100 per opening — about $1,000 off a 10-window project. Meaningful, but the bigger savings come from comparing quotes and from long-term energy bills.
How many quotes should I get?
At least three. Per-opening pricing varies widely between installers for the same windows, and quotes are the only way to pin down your real number — the calculator gives you a baseline to sanity-check them against.
