Owners, users, agents, manufacturers and contractors of boilers or pressurized equipment are responsible for registering equipment designs with TSSA.

Before pressurized equipment is registered, its design is subject to an engineering review to ensure compliance with the Act, Regulations and adopted safety codes and standards.

To register a design, please refer to the appropriate guideline below:

Applications for Ontario Registration

You may be required to complete any of the following Ontario registration documents:
  • Application for CRN for BPV and Fittings 
  • Welding, Brazing Procedure Registration Application for a CRN
  • Piping, Used/Altered Vessel Design Registration Application for a CRN
  • Fitting, Piping, Presure Vessel, Welding Application for a CRN Nuclear
  • Application for Expedited Engineering Services (Please note that rush services are temporarily suspended due to increased submissions. Currently, we are only accepting rush services for piping, hot tapping, sealing enclosures along with refinery outages and nuclear outages.) 

How to Submit an Application

Applications may be submitted to TSSA electronically. Please refer to the Guidelines for Electronic Application. 

Guidelines for Boilers &  Pressure Vessels 

View our guidelines for registration non-nuclear Boilers & Pressure Vessels:
  • Boilers & Pressure Vessels manufactured in Canada
  • Boilers & Pressure Vessels manufactured in the USA
  • Boilers & Pressure Vessels manufactured outside of Canada or the USA

Guidelines for Used and/or Altered Boilers and Pressure Vessels

View our guidelines for design approval of used and/or altered boilers and pressure vessels:

  • Guideline for Design Approval - Used/Altered BPVs

Guidelines for Fittings

View our Fittings Guidelines to learn about registering non-nuclear fittings in Ontario.

Guidelines for Nuclear Systems

View our guidelines for registering Nuclear Pressure Retaining Systems. 

Guidelines for Piping Systems 

You may require the following documents to register piping systems:
  • Piping Guidelines
  • Medical Gas Piping  
  • Piping Data Report

You may also view the Technical Standards and Safety Authority (TSSA) bulletins:

  • Safety Bulletin SB00-7 to help determine if the piping system requires registration.
  • Safety Bulletin SB00-2 Rev.1 for Modifications/Alterations to Registered Conventional Piping Systems

Welding and Brazing Procedures Registrations 

View our Welding and Brazing Guidelines to learn about registering your procedures in the province of Ontario. 

If you need to request an ownership name change on existing welding and brazing procedures currently registered with TSSA, please see the Guideline for Welding/Brazing Procedures - Ownership Name Change.

Design Revisions/Changes

Design revisions are submitted in accordance with application process with a letter describing the design changes.

 

Post construction design changes:

Applicable ASME and CSA codes and standards compliance are required where practical. Refer to variance application where compliance is not feasible and equivalent safety can be demonstrated.  

 

For assistance contact: Shaun Montano, Manager, BPV Engineering, Boilers and Pressure Vessels.

Variance Review 

Variances may be allowed for items that don't fully comply with Ontario Regulation 220/01: Boilers and Pressure Vessels, if the variance will not affect the safe use of the item or the health or safety of any person. Apply for a variance review by completing the Application for Variance form. 

Consultation Services 

Consulting services should be obtained from engineers with industry experience. Engineers can be obtained from your own search or through association websites, such as:

  • Association of Consulting Engineering Companies, Canada
  • Professional Engineers Ontario

The TSSA also conducts preliminary design reviews to determine adherence with safety standards. This service helps assure equipment will be acceptable before it's manufactured.
