What is a CRN (Canadian Registration Number)?

A CRN is a unique identifier assigned by Canadian provincial and territorial authorities that confirms a pressure-containing design has been reviewed and accepted for use within that jurisdiction. Under CSA B51, most pressure vessels, fittings, and piping designs operating above threshold conditions must carry a valid CRN before they can be manufactured, sold, or installed in Canada.

What types of equipment need a CRN?

Pressure vessels (ASME VIII-1 and VIII-2), boilers (ASME I), fittings (Categories A through H under CSA B51), piping systems (ASME B31.3 and B31.1), and specialty items like expansion joints and heat exchangers all typically require CRN registration if they operate above the exemption thresholds defined in provincial regulations.

Do I need a separate CRN for each province?

Yes — pressure equipment must be registered in each province or territory where it will be used. However, seven jurisdictions (NB, NS, PE, NL, YT, NT, NU) share a single registration process through ACI Central Inc. in Charlottetown, PEI.

How long does CRN registration take?

Typical timelines are 6 to 12 weeks from submission to CRN issuance, depending on the jurisdiction and equipment complexity. ABSA (Alberta) and TSSA (Ontario) tend to have the longest review queues.

Can a US manufacturer get a CRN for Canada?

Absolutely. 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.

What is the CRN registration process?

The standard CRN registration process involves six phases: (1) Intake and feasibility review, (2) Document and data validation by our P.Eng. team, (3) Submission package preparation with sealed drawings and calculations, (4) Filing with the designated authority, (5) Technical comment resolution, and (6) CRN issuance and delivery of a complete digital closeout package.

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
Enables unlimited production of identical registered equipment

CRN Registration Process

Our streamlined 5-step process ensures efficient CRN registration across all Canadian jurisdictions.

Design Development (2-4 weeks) — Create ASME code-compliant designs with detailed engineering drawings and specifications.
Documentation Preparation (1-2 weeks) — Prepare comprehensive technical documentation including design calculations and quality control procedures.
Provincial Submission (1 week) — Submit applications to all required provincial jurisdictions with jurisdiction-specific requirements.
Review & Approval (8-20 weeks) — Provincial authorities review submissions and provide approval or request modifications.
CRN Issuance (1-2 weeks) — Receive Canadian Registration Numbers and authorize manufacturing with approved specifications.

Our 6-Phase CRN Registration Process

A proven 6-phase workflow from intake to CRN issuance, managed end-to-end by our P.Eng. team.

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.
Phase 2: Document & Data Validation — Our P.Eng. team reviews your drawings, calculations, material certifications, QC program certificates, and test reports for code compliance. We identify and resolve gaps before submission — not after.
Phase 3: Submission Package Preparation — We assemble the complete CRN application: P.Eng.-sealed drawings, engineering calculations or proof-of-design documentation, cover letter, statutory declaration forms, and all authority-required paperwork.
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.
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.
Phase 6: CRN Issuance & Closeout — Once the CRN is issued, you receive a complete digital closeout package: CRN confirmation, final sealed drawings, and a correspondence log for your records.

Frequently Asked Questions About CRN Registration

What is a Canadian Registration Number (CRN)?: A CRN is a unique identifier issued by provincial and territorial safety authorities in Canada for pressure vessel, boiler, piping, and fitting designs. It confirms that the design has been reviewed by a Professional Engineer (P.Eng.) and meets the requirements of CSA B51 and the applicable ASME construction code. A CRN must be obtained before the equipment can be manufactured, sold, or installed in the issuing jurisdiction.
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. However, seven jurisdictions (NB, NS, PE, NL, YT, NT, NU) share a single registration process through ACI Central Inc. in Charlottetown, PEI. That means a single submission can cover seven CRNs. Ontario (TSSA), Alberta (ABSA), British Columbia (TSBC), Saskatchewan (TSASK), Manitoba (OFC), and Quebec (RBQ/CSA) each require a separate filing.
How long does CRN registration take?: Typical timelines are 6 to 12 weeks from submission to CRN issuance, depending on the jurisdiction and equipment complexity. ABSA (Alberta) and TSSA (Ontario) tend to have the longest review queues. ACI Central can sometimes be faster. Our preparation phase (intake through submission) typically takes 5 to 10 business days for a standard vessel or fitting.
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.-sealed 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?: Absolutely. 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., based in Charlottetown, PEI, handles design registration reviews on behalf of seven jurisdictions: New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, Yukon Territory, Northwest Territories, and Nunavut. This means one submission package and one review process can yield CRNs for all seven. It is one of the most efficient registration pathways in the Canadian system.
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 our P.Eng. team. (3) Submission package preparation with sealed 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.
