Commercial Cleaning

Commercial Cleaning near you

Commercial cleaning is the contracted cleaning of the premises a business runs from: offices, clinics, retail floors, warehouses, schools, and the common areas of multi-tenant buildings. It is normally sold as a recurring service rather than a single job, and the agreement is built around a schedule that sets out what happens nightly, weekly, monthly and quarterly. The work looks straightforward from outside, but it involves regulated hazardous products, staff who often work alone after hours, and keys or access codes to a building when nobody else is in it.

Cleaning is not a licensed profession anywhere in Canada. Anyone can register a company and sell janitorial services, and there is no professional register to search. What is regulated is the safety of the work. The chemicals fall under the Workplace Hazardous Materials Information System, whose classification, labelling and safety data sheet rules come from the Hazardous Products Regulations made under the Hazardous Products Act. Provincial occupational health and safety law then places duties on the cleaning contractor as an employer, and separate duties on the business whose premises are being cleaned.

Because the trade itself is open, a buyer's real leverage sits in three places: a scope of work precise enough to argue from, proof of insurance and workers' compensation coverage, and an agreed way of measuring whether the building is actually clean each month.

Types of commercial cleaning contract, from nightly janitorial to periodic deep cleans

  • Nightly or scheduled janitorial: the recurring core service, done after hours, covering washrooms, kitchens, waste, floors and touchpoints.
  • Day porter or day matron: a cleaner on site during business hours to keep washrooms stocked, deal with spills and reset meeting rooms.
  • Periodic and deep cleaning: quarterly or annual work such as carpet extraction, hard floor stripping and resealing, high dusting and interior windows.
  • Floor care programs: a separate cycle for burnishing, scrubbing and refinishing, often priced and scheduled apart from the nightly scope.
  • Post-construction and post-renovation cleaning: fine dust removal in several passes, which is a different discipline from maintenance cleaning.
  • Regulated environments: clinics, dental offices, food premises and childcare rooms, where the cleaning protocol has to fit the health rules that already govern the space.
  • Disinfection and touchpoint programs: a defined product, contact time and frequency, rather than a general promise to sanitize.
  • Specialty add-ons: exterior windows, pressure washing, waste and recycling sorting, and supply management for consumables.

WHMIS, safety data sheets and who is legally responsible for chemical safety

Cleaning chemicals are not ordinary consumer goods once they are used at work. Health Canada administers WHMIS through the Hazardous Products Act and the Hazardous Products Regulations, which set out how a hazardous product sold or imported for use in a Canadian workplace must be classified, what its supplier label must say, and what its safety data sheet must contain. The Canadian Centre for Occupational Health and Safety explains that safety data sheets run to sixteen standard sections set out in Schedule 1 of those regulations, are normally written by the manufacturer or supplier, and must be readily available to the workers exposed to the product and to the health and safety committee or representative.

The employer side is where most disputes start. CCOHS draws a line between education, meaning the general information about how WHMIS works and what the hazards are, and training, meaning the site- and job-specific procedures for storing, handling, using and disposing of a product and for dealing with spills and emergencies. Every Canadian jurisdiction requires employers to develop, implement and maintain a worker WHMIS education and training program, and CCOHS advises reviewing it at least annually, or sooner when products, processes or hazard information change. Ontario, for example, applies WHMIS through the Occupational Health and Safety Act and its WHMIS regulation.

The building owner does not get to hand all of this to the contractor. Under Ontario's Occupational Health and Safety Act, an employer must take every precaution reasonable in the circumstances for the protection of a worker and must provide information, instruction and supervision, while an owner, defined to include a tenant, lessee or occupier of premises used as a workplace, has duties of its own for the state of the premises. In practice that means telling the cleaning company about hazards in your space, not just expecting their staff to discover them at night.

What a scope-of-work schedule should specify before you sign

  • Every area by name and the frequency for each task in it, rather than a single frequency applied to the whole building.
  • Which tasks are nightly, which are weekly or monthly, and which sit in a separate periodic program with its own dates.
  • The headcount and hours on site, so you know whether the building is cleaned by one person in three hours or three people in one.
  • Who supplies consumables such as paper, soap and liners, who monitors stock levels, and how shortages are reported.
  • Which products will be used in which areas, with their safety data sheets provided, and what happens if a product is substituted.
  • Access arrangements: keys, fobs, alarm codes, who holds them, and the procedure when a cleaner is locked out or the alarm is tripped.
  • Security and privacy expectations for rooms holding records, cash, medication or IT equipment, including which rooms are excluded.
  • How quality is inspected and logged, how a complaint is raised, and the timeframe for putting a missed task right.

Insurance, bonding and workers' compensation: what to ask for in writing

Ask for a certificate of commercial general liability insurance naming the cleaning company, and read the dates and the limit rather than the logo. Cleaners work unsupervised around equipment, water and electrical panels, so the realistic claims are property damage and slips on a wet floor, and you want the policy to be live for the whole contract term, not just the week it was issued.

Bonding is a separate thing and is often misunderstood. A janitorial or fidelity bond responds to theft by the contractor's employees; it is not liability insurance and it is not a licence or a government endorsement. If a company describes itself as bonded, ask what the bond covers, who the named obligee is, and how a claim would actually be made. In buildings where cleaners hold keys to offices containing client records or controlled stock, this is worth reading properly.

Workers' compensation is the third document. In Ontario, the WSIB issues a clearance, a number confirming that a business, contractor or subcontractor is registered and up to date with the board, which only businesses in good standing can obtain and which is valid for a limited period before it has to be refreshed. Asking for a current clearance at renewal, rather than once at the start, is the practical habit. Equivalent boards operate in the other provinces.

Managing the contract after the first month

  • Agree a short written inspection routine, walked jointly at first, so both sides are judging the same building against the same list.
  • Keep a simple log of misses and fixes; patterns matter more than single bad nights and they are what a renewal conversation should turn on.
  • Expect turnover in this industry and ask how a new cleaner is trained on your building's specific scope, products and access rules.
  • Review the periodic program separately, because floor care and deep cleans are the tasks most often quietly skipped.
  • Revisit the scope whenever your space changes: a new kitchen, more desks or a clinical room changes the work and should change the schedule.
  • Keep safety data sheets for the products used in your building accessible to your own staff, not only to the contractor's.
  • Re-check insurance and workers' compensation documents at each renewal date rather than assuming they rolled over.

Where commercial cleaning contracts usually go wrong

  • A price agreed against a vague scope, so both sides genuinely believe different tasks were included.
  • Hours quietly reduced after the first few months, which shows up as dust and detail misses long before anyone can prove it.
  • Periodic work folded into a monthly figure and then never scheduled, so floors degrade over a year or two.
  • Untrained staff using the wrong product on a surface, damaging finishes that cost far more to restore than the cleaning itself.
  • Chemicals decanted into unlabelled bottles, which is both a safety problem and a sign the WHMIS program is not real.
  • Key and alarm handling that nobody documented, discovered only when a cleaner leaves without returning access.
  • No named account contact, so problems escalate to cancellation because there was no one to raise them with.

In-house cleaning staff or a contracted cleaning company

Hiring your own cleaner makes sense when the building is large enough to justify steady hours, when continuity and trust matter more than flexibility, or when the work is entangled with other duties like receiving deliveries and setting up rooms. You then carry the employer obligations directly: training, supervision, coverage during illness and holidays, and the WHMIS program for the products you buy.

A contracted company absorbs recruitment, cover and supervision, brings equipment you would otherwise buy, and can scale a periodic program up for a one-off event or a move-out. The trade-off is distance. You are managing an outcome through someone else's staff, which is why the scope document and the inspection routine do the work that direct supervision would otherwise do.

On LokalMatch, a business describes the premises, the areas to be covered, the frequency and the hours when cleaners can be on site, and commercial cleaning companies working in that city get in touch directly. LokalMatch does not inspect premises or assess a cleaner's work, so treat the insurance certificate, the workers' compensation clearance and the written scope as the checks that matter, and ask for them before the first shift rather than after it.

Commercial Cleaning: frequently asked questions

Do commercial cleaners need a licence in Canada?

No. There is no provincial or federal licence to practise commercial cleaning and no professional register to search, so the title tells you nothing on its own. The obligations that do apply are occupational health and safety duties, including WHMIS education and training for workers who handle hazardous products, and ordinary business registration. Verification therefore means insurance, workers' compensation standing and references rather than a licence number.

What is WHMIS and why does it matter for office cleaning?

WHMIS is Canada's system for communicating the hazards of workplace chemical products through labels, safety data sheets and worker education. Many cleaning products are hazardous products under the Hazardous Products Regulations, which means they arrive with a supplier label and a sixteen-section safety data sheet. Employers must keep those sheets current and readily available to exposed workers, and must train staff on the specific products used in your building.

Should I ask a cleaning company for proof of insurance?

Yes, and read it rather than filing it. Ask for a commercial general liability certificate covering the contract period, and separately for evidence of workers' compensation registration, such as a current WSIB clearance in Ontario. If the company says it is bonded, ask what the bond actually covers, since a fidelity bond responds to employee theft and is not the same as liability insurance.

How detailed should a cleaning scope of work be?

Detailed enough that a dispute can be settled by reading it. List each area, the tasks in it and the frequency of each task, name who supplies consumables, and separate the periodic program such as floor care from the nightly routine with its own dates. Vague wording like general office cleaning is the single most common cause of disagreement about what was purchased.

Does my business have safety duties if I hire an outside cleaning company?

Usually yes. Provincial occupational health and safety law places duties on employers and also on the owner or occupier of premises used as a workplace. In Ontario, for instance, an employer must take every precaution reasonable in the circumstances to protect workers. Practically, tell the contractor about hazards in your space, keep access routes safe for people working alone at night, and share information about any chemicals your own operations leave behind.
