What's different about commercial building cleaning in Montreal

Montreal's commercial buildings skew old and dense: about 36 percent of the city's dwellings, including many mixed-use plex-style walk-ups, were built before 1960, and roughly two-thirds of residents live in buildings under five storeys with flat roofs and brick facades rather than modern towers. Winters bring average January temperatures near -9 to -10.5°C, close to 210 cm of annual snowfall, and repeated freeze-thaw cycles that track salt, grit, and meltwater into lobbies, stairwells, and entryways. That combination of older construction and a harsh shoulder season means commercial spaces here need more frequent floor and entry cleaning than buildings in milder, drier climates.

No provincial trade license is required to clean commercial buildings in Quebec, so vetting comes down to insurance: ask any provider for proof of general liability coverage and workers' compensation board coverage before signing a contract. Demand for one-time deep cleans and post-construction cleanup rises each spring, from March through May, as renovation and build projects wrap up, so booking during winter typically means better availability and rates. In mixed-use neighborhoods like Griffintown, Mile End, and Plateau-Mont-Royal, ground-floor commercial units often share entries and stairwells with upper-floor residential space, which can affect access and cleaning schedules.

Licensing and permits in Quebec

No state/provincial trade license is required to clean commercial buildings, but reputable providers carry general liability insurance and (in Canada) workers' compensation board (WSIB/WCB) coverage — ask for a certificate of insurance before signing a contract.

Residential building permits in Quebec are issued by the local municipality (ville/municipalité), not a provincial agency; each municipality sets its own bylaw thresholds. In Montreal, permits come from the Ville de Montréal — borough permit counters (Permits and Authorizations).

Tax: Labor on home repair/renovation services is a taxable supply in Quebec (no labor exemption) — GST/QST apply to the full invoice including labor, though a partial QST/GST rebate exists separately for new-housing construction or major renovations meeting specific value thresholds.

Best time to book in Montreal

Recurring janitorial contracts run year-round, but demand for one-time deep cleans and post-construction cleanup spikes in spring and after major renovation/build seasons — book deep cleans in winter for better rates and availability. Peak demand: March, April and May. Typical job length: 1-3 hours per routine visit; 1-3 days for a full deep clean or post-construction job.

DIY or pro? Very small offices can get by with in-house staff doing light tidying, but recurring commercial cleaning, post-construction cleanup, and any window work above ground level are almost always outsourced for consistency, equipment, and liability reasons.
