How a Canadian water damage restoration business bills insurers

A water damage restoration business in Canada bills an insurer through three things: a claim file the adjuster can read without a site visit, a direct-billing arrangement the homeowner has signed off on, and a tax invoice that shows the right rate. This guide walks through each one, from the documents an adjuster asks for first to the records the Canada Revenue Agency expects you to keep.

What to take away

How IBC protocols set the file a Canadian restoration firm must produce

The Insurance Bureau of Canada is the trade association for private home, auto and business insurers. Its claims protocols describe how member insurers want losses documented, reported and settled. They carry no legal force, but most adjusters you deal with work from them.

An adjuster may never visit the site. Everything they know about the loss arrives in what you send, so the file has to stand alone.

Documentation standards also come from the Canadian Standards Association and from the IICRC. CSA standards for water damage restoration and mould remediation define how drying is measured, when a job is complete and how materials are classified. The two standards adjusters cite most often are ANSI/IICRC S500 for water damage restoration and IICRC S520 for mould remediation, both built around moisture readings, drying logs and a documented dry standard. Insurers lean on those standards when they question a scope.

Provincial building codes take over once repairs move past drying. The Ontario Building Code, made under the Building Code Act, 1992, governs structural repair, permits and inspections, and a claim file that ignores the permit trail can stall at the repair stage. Confirm the requirement with the authority having jurisdiction rather than assuming a rule carries across a border.

Get intake right and everything downstream is easier. That is the same discipline that keeps your water restoration employee pay and labour costing routine from falling apart when three claims pay late in the same month.

What an adjuster looks for first

If any of those is missing, expect a query rather than a payment. Adjusters rarely reject a claim outright. They ask for the missing item, and the clock restarts.

Where firms lose money on paperwork

Most disputes are not about whether the work was needed. They are about whether the file proves it. A drying log with gaps looks like a guess, and a photograph without a date is worth little.

Scope creep is the other common problem. If your crew dries a room that was not in the approved scope, the insurer may pay for it or may not. Get written approval before the extra work, not after.

Direct billing arrangements and what they change in your invoicing

Direct billing means you invoice the insurer rather than the homeowner. It is common in Canada, but it is a commercial arrangement, not a right. Nothing in law forces an insurer to pay you directly.

When it works, it is clean. You send the invoice and supporting file to the adjuster, the insurer pays you, and the homeowner never handles the money. When it fails, you are chasing a payer you have no contract with.

Before you offer direct billing, decide who your customer is. If the homeowner signed your work authorization, the homeowner owes you. The insurer's payment is a convenience, not a guarantee.

Put the arrangement in writing. State that the homeowner remains responsible for any amount the insurer does not pay, including deductibles, betterment, non-covered items and the difference between your invoice and the insurer's approved amount.

Deductibles are the most common gap. A homeowner with a $1,000 deductible still owes that $1,000, and the insurer will not pay it. Bill it separately and clearly.

Your invoicing has to match the approved scope. If the adjuster approved a scope and you invoice something else, expect a partial payment and a phone call. Reconcile line by line before you send.

Cash flow is the real risk. Insurers pay on their own cycle, and a large loss can sit for weeks. Price the work so a slow payer does not sink you, which is where sensible pricing and profit decisions matter more than volume.

A direct billing workflow that holds up

That sequence is not glamorous. It is the difference between a paid claim and a receivable that ages out.

GST/HST treatment on restoration work billed to insurers versus homeowners

GST and HST apply to restoration services in Canada. Who pays the invoice does not change whether tax applies. It only changes who sends you the money. The Canada Revenue Agency sets the rules a restoration firm follows when it bills insurers and clients.

If you are a small supplier below the registration threshold, you may not have to register. Once registered, you charge tax on taxable supplies, whether the customer is an insurer, a homeowner, a property manager or a condominium corporation.

Most restoration services are taxable at the full rate. An insurance payment for a loss is not a separate supply, so the tax treatment follows the repair work, not the claim.

Some items behave differently. Betterment, upgrades the homeowner requested and non-covered work are still taxable. A deductible is part of the price of the taxable supply, so tax applies to it as well.

The rate you charge depends on where the supply happens. Ontario, Nova Scotia, New Brunswick, Newfoundland and Labrador and Prince Edward Island use the harmonized rate. British Columbia, Alberta, Saskatchewan and Manitoba use GST, and Quebec adds its own provincial tax. A firm working across borders has to know which rate applies.

The CRA explains which rate to charge and collect on a given supply. Ontario's harmonized sales tax guidance is useful for firms billing work in that province, since it sets out how HST applies to services and how it is documented.

Common GST/HST mistakes on insurance work

Each of these shows up in a review. Each is fixable if your invoicing is consistent from the start.

Provincial reimbursement schedules and how they differ across Canada

There is no single national price list for restoration work. Insurers and their adjusters work from provincial reimbursement schedules, industry pricing platforms and their own guidelines. The pricing platforms most Canadian property adjusters use are Xactimate, from Verisk, and Symbility, now part of CoreLogic. Some insurers keep their own unit-price schedules, and smaller provincial markets still run on rate sheets that circulate between adjusters.

A reimbursement schedule sets the unit prices an insurer will pay for labour, equipment, drying, disposal and materials. It is not a law. It is the benchmark an adjuster uses to decide whether your invoice is reasonable.

Ontario has the deepest market and the most competition, so pricing tends to be tight and well documented. Firms there often work from platforms adjusters already recognize.

British Columbia has a different cost base, and WorkSafeBC requirements shape labour rates and site practices. Alberta and Saskatchewan see hail, wind and overland flood losses that drive seasonal claim volume, and their schedules reflect local labour and disposal costs.

Quebec operates in a distinct insurance and legal environment, with its own language and documentation expectations. Manitoba, Nova Scotia and Newfoundland and Labrador have smaller markets where a handful of adjusters handle most claims, so relationships and documentation standards matter a great deal.

Where schedules bite hardest is equipment and drying time. A schedule may allow a set number of days of drying at a set daily rate. If your readings show the job needed more, the drying log is your evidence. Without it, the extra days are hard to defend.

Rough shape of the differences

Travel and disposal are the two lines most often cut. In remote parts of Newfoundland and Labrador or northern Alberta, travel time is real cost. Document it with logs and receipts.

You can negotiate outside a schedule, but only with evidence. A schedule is a starting point, not a ceiling, when the file shows why the job cost more.

Working a schedule dispute

Suppose an adjuster approves five days of drying and your readings show nine. You have the drying log, the moisture readings and the equipment records. You send them with a short note explaining the difference.

The adjuster either approves the extra days or explains the refusal. Either way, you have a written record. That record is what protects you if the homeowner later disputes the invoice too.

Building a claim file that survives insurer review

A claim file is a product. It should be complete, ordered and easy to read. An adjuster working through thirty files on a Monday will pay the clear ones first.

Number your photographs and reference them in the scope. If you say a wall was wet to a certain height, point to the photo that shows it. That single habit prevents most arguments.

Keep a communication log. Note every call with the adjuster, the homeowner and any contractor, with the date and what was agreed. Adjusters change files, and memory is not evidence.

Where repairs are involved, keep the permit and inspection trail. Provincial building codes and local bylaws govern this work, and an insurer will want to see that the repair was done legally. This is also where your licensing and compliance record does double duty: keep the IICRC certifications of each technician and the firm's registration with the provincial authority in the same folder, because an adjuster or an inspector can ask for either.

Subcontractor invoices belong in the file too, with their own tax shown correctly. If a subtrade bills you without tax and you bill the insurer with tax, the gap is yours to explain.

A file checklist

If you want a starting point for the pricing side of the file, a proper quote template keeps your estimates consistent with what you later invoice.

When the insurer pushes back

Pushback is normal. Answer in writing, with the document that addresses the point. Do not resend the whole file, because that signals you have not read the query.

If a dispute escalates, the Restoration Industry Association of Canada and provincial bodies can point you to industry practice. Your own insurer may also matter here, since disputes and bad debts are risks you carry, and insuring a water restoration business properly is part of the answer.

CRA filing, remittance and record-keeping duties for restoration contractors

Registration, filing and remittance are separate duties, and all three fall on you. The tax itself is imposed by the federal Excise Tax Act, and the return a registered firm files is form GST34, the GST/HST return for registrants. The Canada Revenue Agency lays out the business tax obligations that apply to a restoration firm, from registration through to records.

If you are registered for GST/HST, you file returns on a reporting period set by your revenue. Small firms often file annually. Larger firms file quarterly or monthly. The CRA explains how to file a GST/HST return, including electronic filing options and deadlines.

You remit the tax you collected minus the input tax credits you can claim. Input tax credits recover the tax you paid on business purchases, such as drying equipment, vehicles and supplies. Claim them, because they are yours.

You must keep records for six years after the end of the tax year to which they relate. That includes invoices, receipts, bank records, contracts and the claim files themselves. If they are clear and whole, digital copies are acceptable.

Payroll is a separate obligation. If you employ crews, you deal with CPP, EI and provincial workers' compensation, such as WSIB in Ontario or WorkSafeBC in British Columbia. Those costs belong in your job costing, not in a corner of the tax file.

Corporate income tax, and any provincial sales tax where it applies, sit alongside GST/HST. A bookkeeping routine that separates tax collected from revenue is the only way to avoid spending money you owe.

Filing and remittance rhythm

Miss a deadline and interest and penalties follow. The fix is boring: file on time, remit what you collected, and keep the paper.

Common questions

Does an insurer have to pay my invoice directly?

No. Direct billing is a commercial arrangement between you and the insurer, not a legal right. Your contract is with whoever signed your work authorization, so keep the homeowner on the hook for anything the insurer does not pay.

Do I charge GST/HST when an insurer pays the claim?

Yes, if you are registered. The tax treatment follows the restoration service, not the payer. Tax also applies to the deductible, because it is part of the price of the taxable supply.

Which rate do I charge on an out-of-province loss?

The rate depends on where the supply happens. Provinces using the harmonized rate differ from those using GST alone, and Quebec adds its own provincial tax. Check the rule before you invoice, and confirm the current rate with the CRA.

Are provincial reimbursement schedules mandatory?

No. They are benchmarks insurers use to judge whether an invoice is reasonable. You can bill above a schedule if your file shows why the job cost more, which is where drying logs and photographs earn their keep.

How long do I keep claim and tax records?

Six years from the end of the tax year the records relate to. That covers invoices, receipts, contracts, bank records and the claim files that support what you billed.
