Commercial cleaning in Canada typically runs C$756–C$1,136 for a one-time office clean, with real cost differences between provinces and between one-time and contracted recurring service.
For a typical one-time office clean, commercial cleaning costs:
Most commercial cleaning in Canada is actually sold as a recurring contract — nightly, a few times a week, or weekly — rather than a one-off visit. A one-time clean (move-in prep, post-event cleanup, or a single deep clean before an inspection) is priced on its own and tends to cost more per visit than what you'd pay under a recurring contract, since there's no ongoing relationship or routine to make the job faster each time.
If you're a business owner shopping for ongoing janitorial service, always ask whether a quoted monthly rate assumes a specific visit frequency — "weekly" and "nightly" contracts for the same space can differ substantially.
A standard commercial clean covers floors (vacuuming and/or mopping), trash removal, surface dusting and wiping, washroom cleaning and restocking, and kitchen/break room cleanup. Window washing (especially exterior), carpet deep cleaning, and floor stripping/waxing are typically quoted as separate add-ons rather than included in a base janitorial rate.
Commercial cleaning services are subject to GST everywhere in Canada, plus provincial sales tax, QST, or HST depending on your province — the same tax treatment as residential cleaning. If you're comparing quotes between companies, confirm whether the quoted monthly rate is pre-tax or already includes applicable GST/HST, since that can meaningfully change which quote is actually lower.
