How to Start a Window Cleaning Business in Canada

The short answer

There is no window cleaner's licence in Canada, and that is not the same as there being no paperwork. Job Bank records the occupation as unregulated, with no specific education requirements and training usually provided on the job. The gates that actually exist are municipal: some cities license window washing as a business, and Calgary's cleaning-services guide names it explicitly. Add the ordinary service-business paperwork, liability insurance, workers' compensation once you hire, and safety training for heights, and you have the whole barrier to entry. The rest of the business is a route business: windows that get dirty again, customers who rebook, and a reputation built one streak-free pane at a time.

Step 1: Pick residential, storefront routes, or both — and start with one

Window cleaning splits into three lanes that look alike from the sidewalk and run differently as businesses:

• Residential: houses, condos, and townhomes. Jobs are priced per visit, the customer is usually the homeowner, and the selling happens by neighbourhood: door hangers, referrals, and a tidy presence on one street that earns the next street. Interior work matters here, and so does scheduling around the customer's day.
• Storefront routes: shops, restaurants, offices, and salons cleaned on a recurring cycle, usually monthly. The price per visit is smaller, but the route repeats, the income is predictable, and one good route beats a month of one-off residential bookings. The buyer is a manager who wants the glass clean before opening, every time, without being asked.
• Commercial and high-rise: office towers, strata buildings, and institutions. The money is larger and the barrier is real: access equipment, building coordination, fall protection, and insurance certificates a property manager will actually check. This lane is not a first-month lane.

Start with one of the first two. A cleaner advertising homes, shops, and towers in the first month is really advertising that none of them is proven yet. One lane, done well, earns the photos, reviews, and route density that let you add the second.

Step 2: The licensing reality — no trade licence, real municipal rules

Job Bank's window cleaner requirements, drawn from the National Occupational Classification, put it plainly: there are no specific education requirements for the occupation, on-the-job training is usually provided, and according to Job Bank's records the occupation is not regulated in Canada. No province issues a window cleaning trade licence, and no certification is required to practise.

What does apply, and what new operators miss:

• Municipal business licensing: this is the gate that varies by city. Calgary's cleaning-services business guide lists window washing among the businesses that do require municipal licensing, and it treats washing the exterior of a building as cleaning work within that guide. Other cities have their own lists and their own lines, so check the licensing page of every city you work in rather than assuming one city's answer covers the next.
• Business name registration: if you trade under a name other than your own legal name, register it provincially. That registration is separate from a municipal licence, and some cities will want the registered name before they issue the licence.
• Site-specific requirements: a school, a care home, or a venue hosting children or vulnerable people may ask for a criminal record check, and a property manager may ask for proof of insurance and workers' compensation clearance before you touch their glass. These are customer requirements, not licences, but they decide whether you get the job.

Step 3: Register the business and set up tax before the money arrives

The paperwork is the cheapest part of the startup, and it is the part most often left until a customer asks for an invoice:

• Structure: most window cleaners start as sole proprietors and incorporate later, when revenue and liability justify it. If you trade under a name other than your own legal name, register that name provincially.
• Ontario: registering a sole proprietorship under a business name costs $60 through the Ontario Business Registry and lasts five years. Operating under your own name does not require registration.
• British Columbia: request name approval first ($30), then register the sole proprietorship ($40) using the name request number within 56 days, or the approval lapses.
• CRA business number: free, and needed for payroll and GST/HST accounts. Register for GST/HST once taxable sales exceed $30,000 over four consecutive calendar quarters, or voluntarily before that so you can claim input tax credits on equipment, vehicle, and supply costs.
• Municipal business licence: check your city's licensing page. Calgary lists window washing as licensable; your city may differ, and the only reliable answer is the city's own page.
• Bookkeeping from job one: track revenue, supplies, mileage, and time per job, and track it separately for residential visits and storefront routes. A cleaner who knows the cost per route prices with confidence; one who does not drifts into long days for hourly wages.

Step 4: Insurance and workers' compensation

Two conversations, in the order a broker will want them:

• Commercial general liability: covers injury or property damage to someone else — a ladder through a window, solution dripped onto a hardwood floor, a scratched pane on a storefront. A homeowner's policy does not cover your business, and a property manager who asks for your certificate of insurance before you start is doing you a favour by asking early.
• Vehicle and equipment: if you drive a van carrying ladders, poles, and a water system, confirm the vehicle policy covers commercial use and that expensive kit is covered in transit and on site, not just in your garage.

Workers' compensation is the third conversation, and it starts the day you hire. In Ontario, register with the WSIB within 10 days of hiring your first worker if your operation is in a mandatory-coverage industry, and confirm your classification with the board rather than guessing it. Solo operators can apply for optional coverage. Every other province has its own board with its own registration trigger, so register with the board in the province where your crew works, before the crew's first shift.

Step 5: Safety training — heights, ladders, and chemicals

Window cleaning injuries cluster in three places: falls, ladder slips, and chemical exposure. The training maps to those three:

• Working at heights: in Ontario, a worker on a construction project who uses a travel restraint, fall-restricting, or fall arrest system must complete Chief Prevention Officer approved training before using that system, and fall protection is required where a worker may fall more than 3 metres. Second-storey exteriors, work from scaffolding, and work near an unprotected edge all sit in this world. Ontario training is valid for 3 years, with a refresher before expiry. Other provinces set their own thresholds and training rules, so check the rule where the job sits, and keep training records current.
• Ladders: use the ladder rated for the load, set it on firm level ground at the right angle, tie it off where the job allows, and never stand on the top rungs. Inspect the ladder before the job, not after someone notices a wobble, and do not lean a ladder against glass that cannot take the load. A water-fed pole exists precisely to keep the cleaner off a ladder where the pole can reach, and using it is a safety decision, not just a speed decision.
• WHMIS: any worker who handles or may be exposed to a hazardous product must be educated and trained on that product's labels and safety data sheets. For a window cleaner that means cleaning solutions, stain removers, and any chemical used on hard-water deposits. The employer must keep safety data sheets available to workers, keep products labelled, and add workplace-specific training on top of the general course: the actual products on the truck, the actual storage, and the actual spill procedure.
• High-rise boundary: rope access and suspended-access work on tall buildings is a separate specialty with its own training, equipment, and building coordination. Do not take high-rise work on the strength of a ladder and a water-fed pole; if a building needs it, either get the training and the building's contractor requirements first, or refer the job to a high-rise specialist and keep the relationship.

Step 6: Kit — squeegee, water-fed pole, and the vehicle that carries them

The working kit for a residential and storefront cleaner runs: squeegees and channels in several sizes, a washer sleeve and bucket, scrapers for paint and debris, extension poles, a ladder set, drop cloths for interior work, and a vehicle that keeps ladders secured and kit dry. A water-fed pole system with purified water joins the kit once multi-storey exterior work justifies it: the purified water dries spot-free, which is the whole point, and the pole keeps the cleaner on the ground for windows the pole can reach.

Two kit rules that save money:

• Buy the ladder rated for the work you actually do, and buy it once. A cheap ladder that flexes under a cleaner carrying a bucket is not a bargain.
• Keep the water system maintained. A pole system fed with unpurified water leaves the spots the customer paid you to remove, and a clogged brush head slows every job on the route.

Step 7: Pricing jobs — per window at homes, per route at shops

Residential and storefront pricing follow different models, and the right model follows the customer, not the cleaner's habit:

• Residential: price by the window, and define the window on the quote. State whether the count is panes or window units, whether screens, tracks, and sills are included or priced as extras, and whether the price covers interior, exterior, or both. Interior work takes longer per window than exterior work from the ground, so a quote that treats them as the same job will lose money on one of them. Name the two extras that cause disputes before they happen: hard-water stain removal, and paint or construction debris removal, each priced separately.
• Storefront routes: price a set of shops visited on a fixed cycle, usually monthly, with the price covering the agreed glass faces and frequency. Extras such as signage glass, awnings, or interior glass go in the agreement in advance. The route price should assume the cleaner shows up on schedule without being chased, because reliability is the product the manager is buying.
• Commercial one-offs: price from a site visit, with access, height, and interior disruption all seen before the number is given. A phone quote for a building you have not walked is a guess, and the customer will hold you to it.

Whichever model you use, the written quote should state what counts as a window, what is included, and how extras are charged. A deposit is unusual for residential window cleaning; payment on completion after a walk-through of the glass is normal. A quote that hides the screen and track price until the invoice is a dispute, not a price.

Step 8: Finding the first clients — one street, then one route

The first jobs rarely come from advertising. They come from density:

• Start on one street or in one neighbourhood and do it well. A cleaner's van seen twice on the same street sells more than an ad seen once by the whole city, and neighbours ask each other who did their windows.
• Real estate agents, property managers, and strata councils buy window cleaning repeatedly, and they buy on reliability first: show up when promised, send the quote when promised, and finish when promised. One property manager who trusts you is worth a season of ads.
• Storefront routes are won on foot. Walk the street, introduce yourself, leave a card, and quote on the spot for the glass you can see. A shop owner who sees clean glass next door is the warmest lead in this business.
• Before-and-after photos, with the customer's permission, are the portfolio. Photograph in daylight, from the same angle, and keep the customer's belongings out of frame.
• Online listings and a simple website come next: service area, services, photos, and a phone number. Reviews follow completed jobs, not advertising spend — ask every happy customer for one, and answer every review, good or bad, like a person, not a brand.

Step 9: Seasons, water rules, and the Canadian winter

Window cleaning is seasonal in Canada, and the season is managed, not suffered:

• Exterior residential work peaks in spring and fall, when homeowners notice the winter grime and the summer dust. Book the route early in each season, because the same weeks fill for every cleaner in town.
• Interior residential work and storefront routes carry the winter. Shops still want clean glass in January, and homeowners still book interior cleans when the exterior is frozen. A route with enough storefronts is what keeps the winter paid.
• Water rules: some cities restrict exterior washing during severe drought stages, so check your city's water-use rules before booking exterior work in a dry spell rather than assuming the tap is always available. If a restriction applies, reschedule the exterior work and offer the interior clean instead of washing against the rule.
• Weather rescheduling: wind, rain, and freezing temperatures all change the job. Agree the reschedule terms on the quote — who calls, how much notice, and whether the deposit or route fee moves — so a rained-out day is a rescheduled day, not a lost customer.

What not to do

• Do not take paid window work in a city without checking whether that city licenses window washing.
• Do not hire a crew before registering for workers' compensation coverage in the province where the crew works.
• Do not put a worker on fall protection in Ontario without Chief Prevention Officer approved working at heights training.
• Do not take high-rise rope or suspended-access work without the training, equipment, and building coordination that work requires.
• Do not quote a residential job without defining what counts as a window and whether screens and tracks are included.
• Do not mix tap water into a water-fed pole system and expect spot-free glass.
• Do not promise a finish, a date, or a route frequency your kit, your crew, or your ladder cannot deliver.
