Most business owners have no idea whether they're overpaying for cleaning until they get a second quote. After years of cleaning offices, clinics, and commercial spaces across the Greater Toronto Area, here's what it actually costs in 2026, what drives the number, and how to make sure a contract is worth signing.
The real monthly numbers
Commercial cleaning is priced per month, by square footage and frequency. In 2026 across the GTA, a small office up to about 1,000 sq ft cleaned weekly generally runs $480 to $1,000 per month. A mid-size office of 1,500 to 2,500 sq ft cleaned two to three times a week typically lands around $650 to $1,500 per month, and larger spaces of 5,000+ sq ft climb from $1,500 to $4,500+. The spread is wide because layout, traffic, and how often you need service all move the price. You can see how recurring commercial pricing is structured for commercial cleaning across the GTA, and it holds whether you need office cleaning in Toronto or office cleaning in Scarborough.
What actually drives the price
Three things. Frequency is the biggest lever — five-day-a-week service costs far more than once weekly, but the per-visit rate drops as frequency rises. Square footage and layout matter more than most people think; lots of small rooms and washrooms take longer than one open floor of the same size. And the type of space changes everything: a medical or dental office needs disinfection protocols and waiting-room turnover a standard office doesn't, which is why those are quoted separately.
Why recurring beats one-off for a business
For a workplace, a one-time clean is almost never the answer. Dust and washroom hygiene compound fast, and a clean office is a real factor in how clients and staff judge you. A recurring contract locks a predictable monthly cost, keeps the same crew who learn your space, and means you never think about it. The businesses that overpay are usually the ones calling around for emergency one-off cleans instead of a steady schedule.
How to know a quote is fair
Don't accept a price over the phone — any serious cleaning company will do a short walkthrough first, because that's the only way to quote a specific space accurately. Ask what's included (washrooms, kitchen/break room, floors, glass, trash), how often, and whether supplies are covered. Then compare two or three flat monthly quotes side by side. It takes a few minutes to get a flat monthly quote for your space, and a flat rate means no surprise add-ons later.
The bottom line
Commercial cleaning in the GTA isn't expensive when it's scoped right — it's expensive when it's vague. Get a walkthrough, get a flat monthly number, and lock a recurring schedule. A clean workplace for a predictable price is one of the cheapest investments a business makes in how it's perceived.
