How to write a Canadian window cleaning contract that survives winter

What to take away

Why a mild-climate contract fails in Canada

A contract drafted for a temperate climate meets its first real test in a January cold snap or a Calgary chinook. Glass, seals and frames behave differently below freezing, and the person holding the squeegee gets the blame for damage the weather caused.

Canadian work also crosses provincial lines. A crew based in Manitoba may take contracts in Saskatchewan. Each province runs its own consumer protection act, workers' compensation board and occupational health and safety regulator, so one set of terms rarely covers everything.

Winter adds hazards a summer contract never names: ice on ledges, frozen hoses, brittle ladder feet, salt tracked onto glass by tenants. CCOHS guidance on workplace hazards treats weather and site conditions as hazards to identify and control, not background noise.

A winter clause set does three jobs. It moves risk you cannot control to the party who can, it gives both sides a process when weather wins, and it builds the paper trail that supports due diligence after an incident.

What changes between provinces

Consumer protection acts shape cancellation, refund and unfair-term rules for residential clients. Ontario's Consumer Protection Act, 2002 is the best-known example, and comparable statutes exist in British Columbia, Alberta, Quebec and the Atlantic provinces.

Commercial contracts sit largely outside those acts. That makes wording matter more, not less. A commercial client reads the liability cap. A homeowner reads the cancellation fee.

A one-off visit paid on completion rarely needs writing anywhere. Prepayment, a term that runs past one visit, or a sale made away from your premises is what usually triggers the requirement.

What this article does not cover

Nothing here is legal advice. Contract enforceability, tax treatment and employment classification vary by province and by the facts of your business. Have a lawyer licensed in the province where you work review your agreement before you send it.

Cancellation and rescheduling when freeze-thaw stops the work

A clause that treats a blizzard the same as a client changing their mind costs you money in both directions. Split the two events.

Weather delays

Define the trigger in measurable terms. Temperature below a stated threshold, active precipitation, wind above the limit for the equipment in use, or a site made unsafe by ice. When one applies, either side may postpone without penalty and the deposit carries to the new date.

State the notice method. A text or email before the crew leaves the yard is reasonable. A call after arrival, with the van already parked, should trigger a mobilization fee.

Client cancellations

Set a notice window, commonly 24 to 48 hours for residential and longer for commercial. Inside the window, charge a percentage of the job or a flat fee covering fuel, labour and the lost slot. Outside it, rebook free.

Sample wording for the clause: residential visits may be cancelled or moved without charge with 48 hours' notice, and commercial visits need seven days, or the period stated in the service schedule.

Rebooking priority

Say who gets the first open slot after a weather cancellation. Recurring clients outrank one-off bookings. Write the order down so nobody argues in February.

Deposit and refund handling

If you take deposits, state whether they are refundable, how they apply, and what happens when the season ends before the work is done. A clear refund line prevents most complaints to a provincial consumer protection body.

Pricing the fee is easier when the quote already breaks out travel and setup. The structure in this window cleaning quote template translates into the numbers your cancellation clause cites.

Freeze-thaw damage, glass stress and liability wording

This is the clause most often missing and most often needed. Water enters a chip or a failed seal, freezes, expands and lifts a larger piece of glass. The crack shows up days later, and the client calls you.

Your agreement should say you are responsible for damage your work causes, and not for damage from thermal cycling, existing glass defects, failed seals or building movement. It should also require the client to report suspected damage within a set period, commonly 14 days, with photographs.

Document pre-existing condition

Photograph every pane before work begins on the season's first visit. Note chips, scratches, failed seals and cloudy insulated units. Attach the record to the contract or store it with the job file. This is the cheapest defence you can build.

The documenting habits in this guide to window cleaning service quality carry straight into winter.

Cap liability where the client can see it

A cap tied to the value of the job, or to a stated dollar figure, is normal in commercial work. It must be visible, not buried. Courts and consumer protection bodies treat hidden limits badly.

Exclude consequential loss

Say plainly that you are not liable for lost rent, business interruption or replacement of a whole window unit when the damage is to one pane. Commercial clients accept this when it is stated up front.

The due diligence standard

Liability wording and safety practice are connected. The CCOHS explanation of due diligence is the standard a business is judged against when something goes wrong: what did you do, what did you document, was it reasonable. A contract naming inspection, reporting and record-keeping supports that test.

Salt, grit and de-icing residue: who pays

Road salt and de-icing products leave a film that etches glass, pits aluminium frames and stains stone sills. The residue usually arrives from the street, the parking lot or a tenant's own salting, not from your bucket.

Your contract should place responsibility for salt and de-icing residue with whoever applied the product. It should also state what cleaning you will and will not do. Standard washing removes surface film. It does not remove etched glass or corroded metal.

Reporting window

Require the client to report salt damage within a stated period after a visit, with photos and the date. Late claims are hard to attribute and easy to dispute.

Extra work, extra charge

Heavy residue removal is a separate line item with its own price and its own risk language. Do not fold it into the standard rate.

Property manager arrangements

Commercial and multi-residential clients often control their own salting contractor. Ask for the salting schedule and note it in the file. If salt went down the night before your visit, you can document the condition you found.

When the applicator cannot be identified, the client carries the cost. Write that into the clause: unknown applicator, client pays for residue removal and any etching claim.

The short version

State that the client is responsible for damage from de-icing products they or their contractors applied, that you will report visible residue, and that etching or corrosion removal is outside scope unless separately agreed. A short paragraph beats a page.

Salt claims are property claims, and whether your policy answers them is worth confirming before the first freeze. The cost and coverage questions sit in this breakdown of window cleaning business insurance.

Scheduling around chinooks, snow load and short daylight

Alberta chinooks can push temperatures above freezing in mid-January, then drop them again within a day. That swing is the worst condition for exterior glass work: meltwater runs, refreezes and leaves a sheet of ice on the pane you just cleaned.

Chinook and snow-load terms should let you pause, reorder or shift work when those conditions arrive, without triggering a breach. Snow load matters too. A roof or canopy carrying heavy snow is not a place to set up, and provincial regulators expect employers to assess site conditions before work starts.

Daylight is a constraint, not a preference

In December, much of Canada gets under nine hours of daylight, and northern Alberta, Manitoba and Newfoundland get less. Exterior work that needs visibility belongs inside that window. Interior work absorbs the short days.

Building a winter route

Winter routing starts from a shorter working day and a higher chance of a cancelled one. These moves carry most of the benefit.

This is the same discipline that keeps summer routes tight, and the method in this guide to scheduling window cleaning work applies with a weather buffer added.

Communicate changes

Give clients a weekly outlook rather than one fixed date in deep winter. A two-day window with a confirmed start time is easier to keep than a promise the weather can break.

Insurance, workers' compensation and due diligence clauses

A liability clause is only as good as the coverage behind it. Your contract should require current commercial general liability insurance with a stated limit, and name the client as an additional insured where the job warrants it. Whether a given limit is enough for a given building is a question for your broker, not for this page.

Workers' compensation

Provincial boards cover different ground. WSIB in Ontario, WorkSafeBC in British Columbia and WCB Alberta each run their own registration and clearance rules. Commercial clients increasingly ask for a clearance certificate before a crew comes on site. Say in the contract that you will provide one on request.

Employment terms

If you hire, your employment contracts sit under provincial employment standards. Ontario's guide to the Employment Standards Act sets out the rules on hours, termination and written terms your hiring paperwork has to follow. Federally regulated clients and cross-jurisdictional work bring the Canada Labour Code into play.

Cite statutes correctly

When a contract references federal law, cite the statute by its proper name. The Justice Laws Website is the index for federal acts and regulations, and it is the reference a client's lawyer will check.

Privacy and client data

Client contact details, access notes, alarm codes and camera footage are personal information. The Office of the Privacy Commissioner's privacy guidance for businesses sets out expectations for collecting, storing and disclosing it. A short data clause should match what you actually do.

Keep the due diligence file

Retain training records, equipment inspection logs, incident reports and site hazard notes. If a claim or a regulator's visit arrives, those records are the evidence that your clauses describe real practice. A window cleaning compliance checklist is a reasonable starting point for what to keep.

A worked winter clause set

This is a worked example, written to be edited rather than copied. Bracketed items are yours to fill in. Have a lawyer review the set for the provinces you work in.

Clause 1: Weather cancellation and rescheduling

Either party may postpone scheduled work without penalty when the forecast at the site calls for a temperature below [-15 C], active precipitation, wind above [40 km/h], or site conditions made unsafe by ice or snow. Notice must be given by [text or email] before [7:00 a.m.] on the day of service.

Work postponed under this clause is rebooked at no charge, with recurring clients taking priority. Client cancellation with less than [24] hours' notice carries a fee of [$75 to $150] for residential work and [$250 to $600] for commercial work. Both are typical example ranges.

Clause 2: Freeze-thaw damage

The contractor is responsible for damage to glass, frames or seals caused by the contractor's work. The contractor is not responsible for damage caused by freeze-thaw cycling, pre-existing glass defects, failed seals, building movement or thermal stress.

The client must report suspected damage within [14] days of service, with photographs. The contractor's total liability under this agreement is limited to the value of the service, up to [$500] for residential work and [$5,000] for commercial work. Both are typical example caps.

Clause 3: Salt and de-icing residue

The client is responsible for damage caused by de-icing products applied by the client or the client's contractors. The contractor will report visible residue in writing after each visit. Removal of etching, pitting or corrosion is outside the scope of this agreement unless quoted separately in writing.

Clause 4: Chinook, snow load and daylight

The contractor may pause, reorder or reschedule work when rapid temperature change, snow accumulation on roofs or canopies, or reduced daylight makes the work unsafe or ineffective. Such changes are not a breach. Exterior work is scheduled within available daylight hours.

Clause 5: Insurance and clearance

The contractor holds commercial general liability insurance with a limit of at least [$1,000,000] and will provide proof on request. Limits of $1 million to $2 million are typical for this work. The contractor is registered with [WSIB, WorkSafeBC or WCB Alberta] and will provide a clearance certificate on request. The contractor maintains workers' compensation coverage for all employees.

Clause 6: Records and privacy

The contractor keeps inspection photographs, service records and incident reports for [24] months. Personal information collected for scheduling and site access is used only for those purposes and is handled in line with federal and provincial privacy law.

Clause 7: Governing law

This agreement is governed by the laws of the province of [province] and the federal laws of Canada applicable in that province.

How to use this set

Read each clause against your actual practice before you send it. A clause you cannot perform is worse than no clause, because it invites a claim and weakens the due diligence record.

Common questions

Can I use one contract across all provinces?

A single template can work as a base. The cancellation, refund and unfair-term provisions that apply to residential clients come from each province's consumer protection act, so check the wording for every province you serve.

Who pays when glass cracks after a cold night?

Usually the building owner, unless your work caused the damage. Freeze-thaw cracking is thermal, and a clause excluding thermal stress is what keeps the claim off your account.

What notice period is fair for a snow cancellation?

Enough to stop a crew before it leaves the yard. For most residential work that is the evening before or the morning of service. Commercial clients with fixed windows often accept same-day notice.

How long should I keep winter job records?

Pre-work photographs, the service record with date and conditions, any residue or damage report, and the client's acknowledgment. Two years is a common floor, and your insurer or a provincial regulator may expect longer.
