"The single most expensive CRN mistake we see is treating registration as an afterthought. Design for CRN from day one: pick your provinces early, align the calculations with CSA B51 before the drawings are finalized."

What is a Canadian Registration Number (CRN)?

The CRN (Canadian Registration Number) system is the Canadian method of reviewing and registering the design of pressure vessels, piping systems and the fittings used to make them. All Canadian provinces and territories use this system to ensure safety and compliance with national standards.

  • Governed by CSA B51 standard with jurisdiction-specific rules
  • Requires ASME code compliance (VIII-1, VIII-2, B31.3)
  • Registration required for each jurisdiction where equipment is used
  • Typically covers unlimited production of identical registered units

Our 6-Phase CRN Registration Process

A proven 6-phase workflow from intake to CRN issuance, managed end-to-end by a professional engineer.

  1. Phase 1: Intake & Feasibility Review. We assess your equipment type, applicable codes (CSA B51, ASME VIII, B31.3, B31.5), provincial requirements, and the optimal registration pathway. You receive a clear roadmap and list of required documents.
  2. Phase 2: Document & Data Validation. A professional engineer reviews your drawings, calculations, material certifications, QC program certificates, and test reports for code compliance. We identify and resolve gaps before submission, not after.
  3. Phase 3: Submission Package Preparation. We assemble the complete CRN application: P.Eng.-authenticated drawings, engineering calculations or proof-of-design documentation, cover letter, statutory declaration forms, and all authority-required paperwork.
  4. Phase 4: Filing & Authority Communications. We file your application with the designated authority (TSSA, ABSA, TSBC, ACI Central, RBQ, or TSASK) and manage all routine correspondence during the review period.
  5. Phase 5: Technical Comment Resolution (If the authority raises technical queries or requests additional information, we prepare and submit the response on your behalf) included in our standard scope.
  6. Phase 6: CRN Issuance & Closeout. Once the CRN is issued, you receive a complete digital closeout package: CRN confirmation, final authenticated drawings, and a correspondence log for your records.

Frequently Asked Questions About CRN Registration

What is a Canadian Registration Number (CRN)?
A CRN is the number a provincial or territorial authority assigns when it accepts and registers a boiler, pressure vessel, fitting or piping design for use in that jurisdiction. Each province and territory registers designs separately, and the rules on what must be registered, and when, vary by jurisdiction and equipment category. In most jurisdictions a registered design is required before the equipment is installed or put into service.

Do I need a CRN for every Canadian province?
Yes: pressure equipment must be registered in each province or territory where it will be used. ACI Central Inc. processes design registrations for its member jurisdictions. Its Design Registration Application lets one application request registration in any combination of New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador. Yukon, the Northwest Territories and Nunavut register designs through their own chief inspectors. Ontario (TSSA), Alberta (ABSA), British Columbia (Technical Safety BC), Saskatchewan (TSASK), Manitoba and Quebec (RBQ) each require a separate filing.

How long does CRN registration take?
Authority review time depends on the regulator, the equipment category and how complete the file is. Several authorities do not publish a standard review time.
What documents are needed for CRN registration?
Required documents typically include: engineering drawings (assembly and detail), design calculations or proof-of-design documentation (such as burst test reports for fittings), material specifications, a quality control program certificate (where applicable), a statutory declaration form (notarized, for fittings), and a P.Eng.-authenticated cover letter. Specific requirements vary by jurisdiction and equipment type.
What is the difference between a fitting CRN and a vessel CRN?
Fitting CRNs cover components like valves, flanges, pipe fittings, expansion joints, strainers, filters, pressure relief devices, and specialty components. They are registered under CSA B51 fitting categories A through H and typically require a notarized Statutory Declaration plus proof of design (burst test or calculations). Vessel CRNs cover complete pressure vessels designed and built to ASME Section VIII, which require full design calculations, drawings, and a Manufacturer's Data Report.
Can a US manufacturer get a CRN for Canada?
Yes. Many of our clients are US-based manufacturers seeking to sell pressure equipment in the Canadian market. A CRN can be obtained regardless of where the equipment is manufactured; the registration is for the design, not the manufacturing location. Our team handles the entire process, including P.Eng. review and submission to all required Canadian jurisdictions.
What provinces does ACI Central cover?
ACI Central Inc. processes design registrations for its member jurisdictions. Its Design Registration Application lets one application request registration in any combination of New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador. Yukon, the Northwest Territories and Nunavut register designs through their own chief inspectors. Ontario (TSSA), Alberta (ABSA), British Columbia (Technical Safety BC), Saskatchewan (TSASK), Manitoba and Quebec (RBQ) each require a separate filing.

What is the CRN registration process?
The standard CRN registration process involves six phases: (1) Intake and feasibility review to determine applicable codes and jurisdictions. (2) Document and data validation by a professional engineer. (3) Submission package preparation with authenticated drawings and calculations. (4) Filing with the designated authority and managing correspondence. (5) Technical comment resolution if the authority raises queries. (6) CRN issuance and delivery of a complete digital closeout package.
