Register a Design

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.       

Design registration fees for Ontario-only services

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 customerservices@tssa.org.

National Service fees

To register a design in multiple jurisdictions across Canada, see our National Service page. 

How to submit an application

Select the applicable form below according to the type of device you want to register:           

• Boilers, Pressure Vessels and Fittings Design Registration Application for a CRN - Conventional (pdf)

• Welding, Brazing Procedure Registration Application for a CRN (pdf)

• Piping, Used/Altered Vessel Design Registration Application for a CRN (pdf)

• Fitting, Piping, Pressure Vessel, Welding Application for a CRN - Nuclear (pdf)

• Application for the Provision of Expedited Engineering Services (pdf)    

Step 1

Determine the type of non-nuclear pressurized equipment type you want to register and whether you need to register in in Ontario only or in multiple jurisdictions across Canada.        

Step 2

Complete the applicable forms listed above and provide the required supporting documents. Please refer to the applicable guidelines for instructions.        

Step 3

Prepay and submit the completed application form along with supporting documents to TSSA’s Prepayment Portal. 

For payment by cheque, mail your cheque along with a photocopy of your completed application only to TSSA at 345 Carlingview Drive, Toronto, Ontario, M9W 6N9, and email your application form and supporting documents to bpv_registrations@tssa.org.

For payment by wire transfer, scan and submit a copy of the wire transfer remittance along with your application and supporting documents. 

Step 4

TSSA will acknowledge receipt of the application package and assign an engineer to review your application.

Step 5

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.
