CRN FAQs

  • A Canadian Registration Number (CRN) certifies that pressure-retaining equipment (e.g., pressure vessels, boilers, piping, fittings) complies with Canadian codes and has been approved by a provincial or territorial regulatory authority.

  • Each province and territory has its own regulatory body (e.g., ABSA in Alberta, TSSA in Ontario) that reviews applications and issues CRNs for its jurisdiction.

  • Manufacturers, importers, suppliers, and end-users of pressure-retaining equipment operating in Canada.

  • Timelines vary by province and equipment type, typically ranging from 2 to 12 weeks. Our team helps reduce turnaround times by ensuring accurate, complete submissions and avoiding common delays.

  • No. CRNs are issued provincially. However, once approved in one province, it can often be registered more easily in others through a reciprocal registration process.
