Owners, users, agents, manufacturers, and contractors of boilers or pressurized equipment are responsible for registering equipment designs with the Technical Standards and Safety Authority (TSSA) to obtain a Canadian Registration Number (CRN).
Before pressurized equipment is registered, its design must undergo an engineering review to ensure it complies with the Technical Standards and Safety Act, 2000, Ontario Regulation 220/01: Boilers & Pressure Vessels, and adopted safety codes and standards.
Welding and brazing procedures must also be registered. See Welding/Brazing Procedure Registration & Personnel Qualification.
Please refer to the respective application forms or the BPV Fee Schedule - Effective May 1, 2023 (pdf) for engineering service fees.
All fees are payable in Canadian funds and are due upon receipt. Prepayment by credit card is encouraged. Other payment options include a cheque, money order, or wire transfer which may take a longer processing time.
For questions regarding payment, contact the Customer Contact Centre toll-free at 1-877-682-8772 or email firstname.lastname@example.org.
To register a design in multiple jurisdictions across Canada, see our National Service page.

For payment by wire transfer, scan and submit a copy of the wire transfer remittance along with your application and supporting documents.
TSSA will acknowledge receipt of the application package and assign an engineer to review your application.
If the design registration application is approved, TSSA will send the applicant a registration package along with a CRN.
If the application is incomplete, TSSA will request that the applicant provide the required information. This can delay the application process.
