Do Ontario, Quebec, BC and Alberta Require a Water Damage Restoration License?
Water damage restoration license requirements in Ontario, Quebec, BC, and Alberta. Ontario, BC and Alberta have no specific license; Quebec requires an RBQ license.
What to take away
- Canada has no national water damage restoration licence. Each province and territory sets its own rules.
- Short answerOntario has no restoration licence. Quebec requires the RBQ contractor's licence.
- Ontario does not require a specific restoration licence, but municipal permits, WSIB coverage and private certification often apply.
- Quebec requires an RBQ contractor's licence under the Building Act for most restoration work.
- Skipping a required RBQ licence can lead to fines, stop-work orders and denied insurance claims.
Provincial and territorial patchwork
Canada has no state-level restoration licence. Provincial regulators act like state authorities in the United States, while municipalities issue permits for building and sewer work. Private bodies such as the IICRC and RIAC set training standards that insurers and property managers often demand.
This split means a contractor in Ottawa faces different paperwork than one in Gatineau, just across the river.

The table shows the main split, not the full picture. Municipalities can add permit rules of their own.
Ontario rules and work authorizations
Ontario does not issue a water damage restoration licence to contractors. A restoration business must register with the province, keep WSIB coverage for workers, and follow workplace safety rules. If the job involves plumbing or electrical work, those trades have their own licences and permits.
Many insurers and property managers require a technician to hold private certification such as IICRC or RIAC. For a deeper look at training and WSIB requirements, see Certifying water restoration technicians in Canada.
Quebec RBQ licence and what it covers
Quebec takes a different path. Under the Building Act (CQLR, chapter B-1.1), a contractor who performs water damage restoration on building systems needs a licence from the Régie du bâtiment du Québec, known as the RBQ. This applies whether the work is for a private homeowner or a commercial client.
The RBQ issues licences by class and subclass. Building work falls under two classes: general contractor and specialty contractor. Restoration on residential buildings usually needs subclass 1.1. Commercial and institutional jobs fall under 1.2. Plumbing and electrical work carry their own subclasses.
Licence fees depend on the classes and subclasses you apply for and are set by regulation. An unlicensed contractor in Quebec can be fined and may be unable to collect payment through the courts.
Municipal permits and private rules
Local permits still apply. A city may require a building permit for structural drying that alters framing, a plumbing permit for replacing a failed pipe, or a sewer permit for a backwater valve. In Toronto, for example, the basement flooding bylaw sets rules for backwater valves and sump pumps. For Toronto-specific rules, see Toronto basement flooding.
Private rules matter too. Insurers may require a contractor to follow IICRC standards and keep moisture maps. Private guidelines often mirror EPA advice on moisture sources and concealed mold growth after water intrusion. If your firm also takes US clients, 5 cross-border rules apply.
What to submit when applying
A licence or permit application usually needs the same core documents.
Licence and permit application documents
- Business registration and proof of legal name
- Liability insurance and WSIB or CNESST coverage
- Quebec RBQ form with guarantor and security
- Municipal scope of work, site plan, drawings
- IICRC or RIAC certificates when requested
- Business registration, provincial or federal
- WSIB clearance certificate, or a CNESST clearance in Quebec
- Proof of insurance, including commercial general liability
- Trade certificates, or journeyperson cards for regulated trades
- Permit drawings or plans for the work
CSA certification and provincial codes also apply to building materials and electrical work.
What happens if you skip it
In Quebec, an unlicensed contractor who performs restoration work can be fined and ordered to stop work. The RBQ may also refuse a future licence. In Ontario, skipping a municipal permit can lead a building inspector to order the work undone.
Skipping a required licence can also void an insurance claim. Moisture correction comes before mold work, as OSHA guidance on mold hazards states. A contractor who cannot prove authorization may lose the job and face legal exposure.
