What Does Commercial Cleaning Cost in Montreal?
Commercial cleaning costs in Montreal span a wide range — and that range exists for good reason. A 600 sq ft law office suite in a Westmount professional building has almost nothing in common with a 5,000 sq ft fitness centre in Laval or a dental clinic in Brossard. Space type, cleaning frequency, access restrictions, surface materials, and the number of washrooms all feed directly into what you'll pay.
As a general benchmark for 2026: small offices in Montreal typically pay $400–$1,200/month for two to three cleaning visits per week. Medium-to-large office floors — 3,000 sq ft and up — commonly run $2,000–$8,000+/month under a regular contract. One-time or periodic deep cleans sit outside these ranges and are priced separately.
Understanding how pricing is structured is the fastest way to evaluate a quote and make sure you're comparing apples to apples.

How Commercial Cleaning is Priced in Montreal
Montreal commercial cleaning providers use three main pricing models. Each suits a different type of client.
Per square foot is the most common method for ongoing contracts. Rates typically fall between $0.06 and $0.18 per sq ft per visit, depending on the complexity of the space. A straightforward open-plan office at the lower end; a medical office with multiple washrooms and required disinfection protocols at the higher end. Per-sq-ft pricing rewards larger spaces — the rate often drops as square footage increases because cleaning crews become more efficient in larger, consistent environments.
Hourly rate applies most naturally to one-time deep cleans, move-in/move-out cleaning, or very small offices where per-sq-ft math would produce an awkwardly low total. Montreal commercial cleaners typically charge $40–$65 per hour per cleaner. For a small office that takes two cleaners three hours, that's $240–$390 for the visit. Hourly is transparent but adds unpredictability — if the space is messier than expected, the bill climbs.
Flat rate per visit works well for small offices with a fixed, predictable scope: specific rooms, a set number of washrooms, a defined task list. Expect $90–$250 per visit for offices under 1,000 sq ft. The advantage is simplicity — you know the cost before each visit. The trade-off is less flexibility if your needs change visit-to-visit.
Which model is right for you? If you have a defined space cleaned on a regular schedule, per-sq-ft contract pricing is almost always the most cost-effective. Hourly suits one-time work. Flat-rate is ideal for micro-offices or satellite locations with very consistent cleaning requirements.

What Drives the Price of Commercial Cleaning in Montreal
Seven factors determine where your quote will land within any given range.
1. Square footage and layout. Larger spaces cost more in absolute terms but less per sq ft. Layout matters as much as total area: an open-plan floor takes a crew far less time than the same square footage broken into private offices, cubicle clusters, and narrow corridors. Each transition between zones adds time.
2. Frequency. Counterintuitively, more frequent cleaning is cheaper per visit — not more expensive. A space cleaned three times per week accumulates far less buildup between visits than one cleaned weekly. Less buildup means shorter dwell time for each visit, which keeps per-visit pricing lower. Daily service offers the best per-visit rate; weekly service is the most expensive per visit.
3. After-hours access requirement. Downtown Montreal office towers — particularly along Peel, McGill, and René-Lévesque — almost universally require after-hours cleaning between 6 PM and 8 AM. This reflects building management policies and tenant comfort, not cleaner preference. After-hours work carries a 15–25% premium over standard daytime rates, reflecting overtime labour costs and the extra coordination of key fob access, after-hours building sign-in, and security protocols.
4. Number of washrooms and kitchens. Washrooms are the most time-intensive element in commercial cleaning. Each washroom adds approximately 20–35 minutes to a visit, and providers weight washroom count heavily in their quotes. A 1,500 sq ft office with four individual washrooms will cost meaningfully more than a same-sized office with one. Kitchen and break-room cleaning adds similar weight: sink, counters, appliance exteriors, and trash require close attention.
5. Surface types. Different floor materials require different equipment, products, and time. Carpet requires only vacuuming on regular visits (and periodic extraction separately). Polished concrete needs a pH-neutral mop solution and specific technique to avoid streaking or surface damage. Ceramic tile with grout lines requires more scrubbing time. Glass partitions — common in modern Montreal tech offices — require streak-free spray and microfibre technique on every visit. The more surface variety in a space, the more complexity in the quote.
6. High-touch-point density. Medical offices, childcare facilities, and food-prep environments carry a 20–40% cleaning premium because they require hospital-grade disinfection products and documented protocols, not standard commercial cleaning. Every door handle, light switch, counter surface, and shared device must be treated with appropriately rated disinfectants. This takes longer and uses more expensive consumables.
7. Security and access complexity. Some contracts — particularly for government tenants, aerospace facilities in Saint-Laurent, and financial services firms — require background checks, key fob management, after-hours security sign-in logs, or compliance with specific GSC (Government Security Clearance) protocols. This administrative overhead and the smaller pool of eligible providers pushes pricing upward.

Montreal Business Districts: How Location Affects Commercial Cleaning Rates
Where your business sits in Greater Montreal shapes your cleaning options and cost.
Downtown core (Peel / McGill / René-Lévesque towers): After-hours cleaning is effectively mandatory in most Class A towers. High occupancy density means washrooms and common areas need more frequent attention. Expect per-sq-ft rates at or above the midpoint of market ranges.
Griffintown / Cité du Multimédia (tech and creative sector): Polished concrete floors, open-plan layouts, and floor-to-ceiling glass partitions are standard. Cleaning crews need experience with concrete-safe products and streak-free glass technique. Rates are typically mid-range, but the right provider matters more here than in conventional carpet-and-drywall offices.
Technoparc / Saint-Laurent (aerospace and biotech): Regulated-environment protocols are common. Fragrance-free products are frequently required. Some contracts go through a formal RFQ (Request for Quotation) process. Providers need documented quality systems, which limits the field and can push pricing higher.
South Shore / Brossard (DIX30 and suburban office parks): Easier access, on-site parking, and daytime cleaning windows are often available — which removes the after-hours premium. Per-sq-ft rates here tend to be at the lower end of the Montreal market.
Laval (Chomedey / Saint-Laurentians corridor): Strong demand for bilingual service (French/English) is common. Access and parking are generally straightforward. Rates are comparable to South Shore suburban rates — typically 5–10% below downtown Montreal.

Medical and Healthcare Office Cleaning: A Separate Tier
Dental offices, medical clinics, physiotherapy practices, and optometry offices operate under a distinct cleaning standard — and pricing reflects that. Medical commercial cleaning in Montreal typically runs 15–30% above comparable-sized standard offices.
The reasons are specific: CNESST infection-control protocols require hospital-grade disinfectants rather than standard commercial products. Washroom density is typically higher per square foot than in office environments. Zones adjacent to sharps disposal require careful handling. Many health practices require staff sign-off on cleaning completion logs for health inspection compliance. These requirements narrow the field to providers with appropriate training and documentation, and that specialization carries a justified premium.

Contract vs. On-Demand: Which Is Better for Your Business?
Monthly contracts offer stable pricing locked in at the start of the agreement, priority scheduling with a consistent crew who learn your space, and typically the lowest per-visit rate. Providers plan labour more efficiently for contracted clients, and that efficiency passes through as savings.
On-demand cleaning offers flexibility: book when you need it, skip when you don't. The trade-off is a 20–40% premium per visit versus contracted rates, no priority access during peak periods, and a different crew each time who need to relearn the space.
The practical recommendation: if your space is over 500 sq ft and you need cleaning two or more times per week, a monthly contract almost always saves money over the course of a year — and the consistency in quality is better. Reserve on-demand for genuinely occasional needs: a single post-event clean, a one-time move-out clean, or a supplementary deep clean outside your contract scope.

Frequently Asked Questions
Q: How much does it cost to clean a 1,000 sq ft office in Montreal?
A: A typical 1,000 sq ft office in Montreal runs $120–$200 per visit for weekly cleaning, or $1,200–$2,000/month for 3 visits per week. After-hours cleaning adds 15–25%. Your first quote may be higher — most providers do a walkthrough to assess layout complexity, number of washrooms, and surface types before locking in a price.
Q: Is commercial cleaning priced per square foot or hourly in Montreal?
A: Most Montreal commercial cleaning contracts are quoted per square foot for ongoing service ($0.06–$0.18/sq ft per visit). One-time or occasional cleans are often quoted hourly ($40–$65/hr per cleaner). For small offices under 800 sq ft, a flat-rate per-visit quote ($90–$180/visit) is also common. Per-sq-ft contracts typically save 15–25% versus paying hourly once you have a regular schedule.
Q: Does commercial cleaning cost more after hours in Montreal?
A: Yes — most downtown and high-rise office buildings in Montreal require after-hours cleaning (between 6 PM and 8 AM), which adds a 15–25% premium to standard daytime rates. This reflects overtime labour costs and the added coordination of night-key/fob access. If your building allows daytime cleaning (some suburban office parks do), you can avoid this premium.
Q: What's the difference between commercial cleaning and janitorial service?
A: Janitorial service typically refers to daily or near-daily maintenance cleaning — trash removal, washroom restocking, vacuuming, and surface wipe-downs. Commercial cleaning covers the same scope but also includes less-frequent deep-cleaning tasks: floor scrubbing/buffing, interior window washing, kitchen appliance cleaning, and periodic disinfection of high-touch zones. Many Montreal providers offer both under one contract.
Q: Do medical and dental offices pay more for commercial cleaning?
A: Yes — typically 15–30% more than a comparable-sized standard office. Medical and dental offices require hospital-grade disinfectants (not standard commercial products), more washroom cleaning per square foot, careful handling of zones near sharps disposal, and documentation of cleaning protocols for health inspections. This specialization justifies the premium.
Q: How far in advance should I book a commercial cleaning service in Montreal?
A: For an ongoing contract, 1–2 weeks is typically enough notice for providers to schedule a walkthrough and start service. For one-time or periodic deep cleans, book 1–3 weeks out. The exception is peak moving season (June–July) and pre-holiday deep cleans (November–December) — in those windows, 3–4 weeks advance booking is safer. Downtown Montreal daytime slots also fill faster than after-hours slots.
