The CRN Submission Package: Drawings, Calculations and Quality Documents Regulators Expect

By Kopfkino Consulting Corp. · Published September 14, 2026 · Updated October 17, 2026 · 11 min read

What regulators expect in a CRN application: drawings, code calculations, statutory declarations, quality-program evidence, PRD sizing and nameplate details, with province-specific variations.

A CRN application typically requires a completed jurisdictional application form, fabrication drawings showing design conditions and CRN stamping, code calculations (ASME VIII for vessels, ASME B31 for piping), a statutory declaration for fittings, proof-test reports where applicable, quality-program evidence, and a nameplate facsimile. P.Eng. authentication rules and submission channels vary by province; incomplete packages are refused or closed.

Every Canadian Registration Number starts the same way: a document package submitted to a provincial or territorial safety authority for engineering review. Yet the most common cause of CRN delays is not design complexity; it is incomplete or inconsistent submissions, and no regulator accepts a generic "datasheet pack" in place of a proper design-registration package. This article inventories what goes into a CRN submission for each registration type, plus the quality documentation, P.Eng. authentication rules and submission mechanics behind a prompt review.

What documents go in a pressure vessel or boiler CRN application?

A vessel or boiler registration package is the most document-intensive of the three registration types. Across jurisdictions, regulators expect the following core set (forms vary by province):

• Completed application form. Alberta uses Form AB-31 with the AB-31a supplement; Saskatchewan uses TSK-1011 with TSK-1003; Ontario uses form 2017-PV-09558; the RBQ has its own application; ACI Central's form covers its seven member jurisdictions (PE, NB, NS, NL, YT, NT, NU). Technical Safety BC's design registration page and portal serve as the anchor checklist for BC submissions, verify the current TSBC checklist before submitting.
• Fabrication drawings showing design pressure and temperature, MAWP, MDMT, materials, dimensions, nozzle schedule, weld details, the CRN stamping location, and a nameplate facsimile showing exactly how the registered design will be marked.
• Design calculations to the code of construction: for most vessels, ASME VIII Division 1 or 2 (shells, heads, nozzles, reinforcement, external pressure). Non-standard U-2(g) designs need a user design specification and, where FEA is used, a certified report: ABSA expects P.Eng.-certified FEA (per AB-520), TSASK accepts FEA meeting CSA B51 Annex J, and Quebec has struck Annex J out of its adopted code (r. 6.1 s. 9).
• Statutory declaration where required, mandated in Alberta (PESR, AR 49/2006, s. 17).
• Quality-control program evidence (see below) and pressure-relief sizing documentation demonstrating adequate overpressure protection.
• Provincial extras. TSASK requires an owner letter for Category D (lethal) fluid service; BC requires a P.Eng.-signed Qualified Professional Declaration.

Registration must be obtained before construction begins in British Columbia (BC Reg. 104/2004, s. 84(5)); Ontario permits construction at the applicant's risk after submission (O. Reg. 220/01, s. 4(2)). After fabrication, the manufacturer's data report (MDR, e.g., ASME Form U-1) must reach the destination jurisdiction, the RBQ within 30 days of signing, Manitoba by email when a unit ships, and Ontario via installation inspection before first service.

What documents go in a fitting CRN application?

Fittings (CSA B51 Table 1 Categories A through H, from pipe fittings and flanges to valves, expansion joints, measuring devices and pressure relief devices) follow a lighter but highly standardized package:

• Statutory declaration. A harmonized multi-province form exists: one form, tick the jurisdictions sought, with checkboxes for categories A-H (and N for nuclear). Alberta uses Form AB-41, Saskatchewan pairs TSK-1014 with TSK-1008, and Ontario uses form 2017-PV-09553, which must be notarized before scanning. It must be signed by an officer of the manufacturer, and the registration is issued in the manufacturer's name. Under Ontario's January 2026 Fitting Registration Guidelines, a Declaration of Conformity is filed electronically with a cover letter, scope of registration, QC certificate, and proof of other-province registrations.
• Drawings or catalogue pages fully defining the pressure boundary, dimensions, materials, pressure-temperature ratings, end connections.
• Calculations or proof-test reports. Where calculations cannot establish the rating, burst/proof testing per ASME VIII-1 UG-101 is the accepted route, with published safety factors (a factor of 10 applies for glass and certain non-metallic components).
• Quality program certificate issued or accepted by the authority having jurisdiction (AHJ) of the place of manufacture, plus a list of manufacturing locations. Ontario requires Category G primary overpressure devices to hold ASME certificates of authorization.
• Expiry discipline. Fitting registrations expire 10 years after first acceptance (CSA B51) and must be resubmitted for validation; a lapsed QC program at a manufacturing site invalidates the CRN.

Note that BC, Saskatchewan, Manitoba and Quebec exempt standard Category A, B, C and (usually) G fittings built to listed ASME standards; Alberta, Ontario and the ACI jurisdictions do not.

What documents go in a pressure piping CRN application?

Piping registration is registration of the system design, so the package is defined by system documents rather than component drawings:

• P&IDs covering all pressure equipment in scope.
• Line lists stating, per line: size, material, schedule, design/maximum pressure and temperature, MDMT, corrosion allowance, NDE/radiography, test medium and pressure, and PWHT (TSASK's requirements are the most explicit).
• General arrangement/layout and isometric drawings, plus the piping specification.
• Bill of materials identifying the CRN of every fitting in the system. Ontario requires an attestation that only registered fittings are used; TSASK reviewers cross-check line lists against fitting registrations.
• Flexibility/stress analysis where applicable under the governing ASME B31 code.
• Pressure relief device list with capacities and set pressures, an overpressure-protection statement, and the pressure/leak test procedure.
• Construction data reports at completion: TSK-1002 (Saskatchewan), FRM-1329 (BC), AB-83/AB-81 (Alberta), the Piping Installation and Test Data Report (Ontario), and the RBQ declaration of installation, filed at least 30 days before work completion (r. 6.1 s. 32) and itself the Quebec piping-registration event.

Ontario's piping guideline (January 2025) also requires drawings to show the construction code (B31.1/B31.3/B31.5; B31.9 excluded), fluid and fluid-service category, design P/T, test pressure and type, and PRV setting and location. Saskatchewan's skid program (IP-2016-07-04) adds skid nameplates and stand-alone overpressure protection, no shared PRD discharge headers.

Worked example: one vessel and one piping package through ABSA (Alberta)

A fabricator registers two designs for equipment destined for an Alberta facility.

ASME VIII vessel package: 1. Form AB-31 with the AB-31a supplement. 2. Fabrication drawing showing design pressure and temperature, MAWP, MDMT, materials, nozzle schedule, weld details, CRN stamping location, and a nameplate facsimile. 3. ASME VIII-1 design calculations (shells, heads, nozzles, reinforcement, external pressure). 4. Statutory declaration, mandated under PESR (AR 49/2006) s. 17. 5. QC-program evidence and pressure-relief sizing documentation.

Piping package (ASME B31.3 system): 1. P&IDs covering all lines in scope. 2. Line list stating per line: size, material, schedule, design pressure and temperature, MDMT, corrosion allowance, NDE/radiography, and test medium and pressure. 3. General arrangement/layout and isometric drawings, plus the piping specification. 4. Bill of materials identifying the CRN of every fitting. 5. Flexibility/stress analysis where applicable under B31.3. 6. Authentication by an Alberta P.Eng. (APEGA): required for piping designs.

Both packages are filed through the ABSA CRN Portal (apps.crnonline.ca), and a construction data report (AB-83/AB-81) closes out the piping system at completion.

What quality documentation do regulators expect?

Quality documentation underpins every registration type:

• ASME Certificates of Authorization (U, S, PP stamps, etc.) for the fabricator, with the ASME stamp and, for foreign fabrication, National Board registration, the smoothest route for vessels built outside Canada.
• A QC program or manual accepted by the AHJ of the manufacturing location. CSA B51:24 Annex F sets out the QC framework for fitting manufacturers. Alberta requires in-province manufacturers to hold an ABSA-registered Alberta Quality Program (AQP) with a Certificate of Authorization Permit ($1,253.50 plus hourly review, minimum 4 hours, as of November 2025). Quebec issues permits following QC-program approval, valid three years.
• ISO 9001 certification is commonly referenced on statutory declarations as quality-system evidence and often forms part of the QC-acceptance basis for offshore plants, but confirm acceptance with each AHJ, as it is not universally sufficient alone.

Which provinces require a P.Eng. authentication of the submission?

P.Eng. (professional engineer) authentication is one of the sharpest provincial differences:

How and where do you submit the package?

• Alberta: ABSA CRN Portal (apps.crnonline.ca)
• British Columbia: TSBC Design Registration Portal
• Saskatchewan: TSASK online Design Submission Portal
• Ontario: TSSA Client Portal: mandatory since April 29, 2024, with prepayment through the Service Prepayment Portal
• Quebec: email to enregistrementdesplans@rbq.gouv.qc.ca (French documentation or certified translations are industry-reported practice; confirm with RBQ)
• Manitoba: one PDF to qasupport@gov.mb.ca with prepayment
• Atlantic provinces and territories: ACI Central portal (acicrn.com/aciexternal), one submission covers all seven member jurisdictions, though only the chief inspectors legally issue CRNs

TSSA's National Service (form BPV-004) coordinates multi-province registrations, including ACI routing, for an additional fee and deposit (corroborated at $1,200 including $500 admin; confirm current amounts).

Completeness checklists and what happens when packages fall short

Regulators have hardened their completeness gates. TSSA does not process applications missing mandatory documents (since February 1, 2025), allows 21 calendar days to answer information requests before closing the file, and treats queries unanswered for roughly 30 days as withdrawal, with re-feeing on resubmission. ABSA, TSBC and TSASK return or hold incomplete packages. A disciplined pre-submission completeness check: every form signed, every drawing revision-consistent with the calculations, every fitting CRN verified, is the cheapest schedule protection available.

Common mistakes

• Wrong signatory or missing notarization on the statutory declaration; it must be signed by an officer of the manufacturer; Ontario's form must be notarized before scanning.
• Registration in the wrong name, fitting CRNs are issued in the manufacturer's name, not a distributor's or agent's.
• Missing P.Eng. authentication where required (Ontario, Quebec, Alberta piping, Saskatchewan skids/piping), or over-applying seals where ABSA says they are not required.
• Drawings inconsistent with calculations, mismatched design pressures, MDMT values or materials between drawing, calc package and line list.
• Unregistered fittings in a piping BOM: reviewers cross-check; one unregistered valve stalls the whole system registration.
• Wrong or expired code edition references. B51:24 clause numbers differ from B51-14; Nova Scotia pins B51-19 and Yukon pins B51-14.
• Assuming A/B/C/G fitting exemptions are Canada-wide: they apply in BC, SK, MB and (for A/B/C piping accessories) QC, but not in AB, ON or the ACI jurisdictions.
• Missing MDMT or impact-test data, especially under the new CSA B51:24 carbon-steel toughness clauses.
• Stale QC certificates: a lapsed quality program at the actual manufacturing site invalidates fitting registrations.
• Late regulator engagement for foreign fabrication: inspection-agency acceptance must precede fabrication; TSBC warns retroactive registration can be "very expensive/burdensome or impossible."

Best practices

Engineering recommendations, not regulatory requirements:

• Build a master document index per registration type and jurisdiction; assign one document controller as package owner.
• Freeze drawing and calculation revisions together and cross-check every design condition (P, T, MDMT, materials) across all documents before submission.
• Verify every fitting CRN in the BOM against the destination province's suffix (Alberta requires a "2" or "C" after the decimal).
• Engage the AHJ-accepted inspection agency before fabrication at any shop outside Canada.
• Track fitting CRN expiries on a 10-year cycle and synchronize renewals across jurisdictions.
• Answer regulator information requests well inside the response window (21 days in Ontario).

Frequently Asked Questions

What documents do I need to include in a CRN application?

At minimum: the jurisdiction's application form, fabrication drawings (with design conditions and a nameplate facsimile), code-of-construction calculations, a statutory declaration where required, QC program evidence, and P.Eng. authentication where the province requires it. Piping systems add P&IDs, line lists, a BOM with fitting CRNs, and stress analysis where applicable.

Do CRN drawings need to be stamped by a professional engineer?

It depends on the province and equipment type. Ontario always requires a PEO-licensed P.Eng. authentication on vessel and boiler designs (O. Reg. 220/01 s. 4(3)); Quebec requires an engineer's signature; Alberta requires an Alberta P.Eng. on piping designs but not by default on vessel drawings; Saskatchewan requires an SK P.Eng. on skid and piping packages.

What is a statutory declaration for CRN registration?

A sworn statement by an officer of the manufacturer declaring code compliance and a maintained quality program. A harmonized multi-province form covers most jurisdictions for fittings; Alberta requires it under PESR s. 17, and Ontario's version must be notarized.

Can I submit one package to cover all of Canada?

Partially. ACI Central reviews one package for seven jurisdictions, and the RCT Reconciliation Agreement enables mutual recognition among nine participating jurisdictions. Alberta always conducts its own ABSA review, so Canada-wide coverage involves at least three tracks.

How long are fitting CRN documents valid?

Fitting registrations expire 10 years after first acceptance and must be resubmitted for validation (CSA B51). Supporting records and declarations should be retained at least 10 years, and the QC program must remain in force at each manufacturing location.

What happens if my CRN application is incomplete?

TSSA does not process applications missing mandatory documents (since February 2025) and closes files if information requests go unanswered for 21 calendar days; lapsed queries lead to withdrawal and re-feeing. Other regulators return or hold incomplete packages, resetting review queues.

Do I need to register before I start fabricating?

In British Columbia, yes: registration is required before construction begins (BC Reg. 104/2004 s. 84(5)). Ontario allows construction at the applicant's risk after submission. Submitting before fabrication is the only safe approach everywhere, since retroactive registration can be impossible.

Key Takeaways

• A CRN submission package has three layers: application forms and declarations, technical design documents (drawings, calculations, P&IDs/line lists), and quality documentation (ASME CoA, QC program, ISO 9001 evidence).
• Vessel packages centre on ASME VIII calculations and fabrication drawings; fitting packages on the harmonized statutory declaration plus calculations or UG-101 proof tests; piping packages on P&IDs, line lists and BOMs with fitting CRNs.
• P.Eng. authentication rules differ sharply by province: Ontario always, Alberta piping only, Saskatchewan skids/piping, Quebec vessels/boilers.
• Fitting registrations expire after 10 years and depend on a maintained QC program at each manufacturing site.
• Incomplete applications are refused or closed. Ontario enforces a 21-day response window; a rigorous completeness check is essential.
