The Régie du bâtiment du Québec (RBQ) announced on February 11, 2026 that a draft amendment to Quebec's pressure installations regulation, the Règlement sur les installations sous pression, had been published for comment. The draft text in the Gazette officielle touches definitions, referenced codes, installation paperwork, mobile equipment permits and owner obligations. Boilers, both steam and hot-water, sit squarely within its scope.
What was published
The short answer: a draft, open for 45 days, that updates the codes Quebec's pressure-equipment rules point to.
The RBQ summarised the draft's aims as:
- updating the standards and codes the regulation incorporates by reference
- aligning requirements and definitions with other provinces to support labour mobility
- improving public safety and traceability, including operating permits for mobile pressure installations and periodic inspections by the RBQ
- giving manufacturers, repairers, installers and operators clearer tools to meet their obligations
- reducing some administrative formalities
The Gazette notice, signed by Quebec's labour minister, says the government could approve the regulation, with or without changes, once 45 days had passed. It estimates about $2.2 million in additional business costs in the first year and about $2.4 million a year in savings afterwards.
Changes boiler companies will notice
These are our summaries of the draft's French text. The draft is the authority, and it may change before adoption.
- Code editions. A general reference to CSA B51 becomes CSA B51:19. The refrigeration code is named as CSA B52:23.
- Construction codes by boiler type. High-pressure boilers are to be built to ASME Section I, low-pressure boilers to ASME Section IV, and pressure vessels to ASME Section VIII.
- New definitions. The draft defines terms such as pressure equipment, installation work and maximum allowable working pressure, and clarifies that "low pressure" in one paragraph refers to hot-water boilers.
- Installer declarations. Before commissioning, the installer would send the RBQ the manufacturer's declaration of conformity and a photo of the nameplate for each piece of equipment, plus a periodic inspection certificate for used equipment.
- Unregistered designs. A boiler or pressure vessel whose design was not registered with the RBQ would need an RBQ inspection before receiving a Quebec identification number.
- Owners who stop using equipment. Anyone who stops using or disposes of pressure equipment would have to notify the RBQ within 30 days, or remain responsible for it.
- Mobile installations. Owners of mobile pressure installations would need an operating permit, with a listed fee of $199.96.
How this fits the national picture
Quebec naming CSA B51:19 places it closer to Alberta, which, as our ABSA story reports, also kept the 2019 edition. Ontario, British Columbia and Manitoba enforce the 2024 edition. The draft's stated goal of interprovincial alignment is about definitions and requirements broadly, not one edition number.
Analysis: what Quebec boiler companies should prepare for
This section is our analysis, not the RBQ's.
If the installer-declaration rule is adopted as drafted, every commissioning becomes a small document-gathering exercise: conformity declaration, nameplate photo, and for used units, a current inspection certificate. Companies that build that into their job checklist will avoid delays; companies that don't may find commissioning dates slipping.
For marketing, the opportunity is bilingual clarity. Quebec buyers search in French first, and a short, dated page in French and English explaining what the RBQ requires, and linking the RBQ, is more useful than generic copy. Our Quebec page covers the province's regulators and programs, and our regulation content service produces this kind of page for contractors.
Open questions
Several points could not be settled from the public documents we read:
- Final adoption. We found the draft and the RBQ's announcement, but not a final regulation. Drafts in Quebec are often adjusted after comments, so details above may change.
- Coming-into-force date. The draft's transitional provisions refer to the day before the regulation takes effect, with the date left blank for the final text.
- Licence holders' transition. The draft lets existing permit holders keep applying one earlier rule until their permit is renewed or changed. How that plays out depends on each holder's renewal date.
The RBQ's draft regulations page and the Gazette officielle are the places to watch. When a final text is published, we'll write a new story with that document's date rather than quietly editing this one.

Frequently asked questions
Is the new Quebec regulation in force?
As of our October 2026 check, we had only seen the draft. The Gazette notice said the government could approve it, with or without changes, after a 45-day comment period, so confirm its status with the RBQ.
Which CSA B51 edition does the draft name?
The draft replaces a general reference to CSA B51 with CSA B51:19. It also names CSA B52:23 for mechanical refrigeration.
What does the draft cost businesses?
The Gazette notice estimates about $2.2 million in extra costs for businesses in the first year, mostly small and medium-sized firms, and savings of about $2.4 million a year after that.
Does this article offer legal or compliance advice?
No. It summarises a public draft. Questions about obligations under the regulation belong with the RBQ.
