The Technical Standards and Safety Authority (TSSA) reviews fuel system and device design submissions to ensure compliance with the Technical Standards and Safety Act, 2000, as well as any applicable regulations and adopted safety codes or standards.
The TSSA’s Fuels Safety Program offers several other engineering services, including design approvals, variance approvals, equipment field approvals, and more.
The Fuels Safety program also offers expertise in the following areas:
Engineering Applications
To request an engineering approval, please complete and submit the appropriate application form(s) and supporting document(s) to our Prepayment Portal. Supporting documents must be submitted as individual files. Do not combine all documents into a single file. Incomplete submissions will not be processed. Turnaround times depend on the completeness and quality of the submission.
If you need help, please contact customer service at 1-877-682-TSSA (8772) or email customerservices@tssa.org.
Mandatory Supporting Documents for Fuels Engineering Applications
To enhance the efficiency of processing engineering applications submitted for fuel systems and devices, engineering applications submitted after February 1, 2025, without mandatory supporting documents will not be processed. All fees are non-refundable.
Submitting mandatory supporting documents along with the application is critical to ensure the timely processing of design registrations. Please ensure that mandatory supporting documents are complete.
Please refer to the list of mandatory supporting documents for Fuels Engineering Reviews.
Field Approval Program
The Field Approval Program is an approval process for custom-made appliances that are limited in number and cannot be certified by designated certification organizations.
Learn more about the Field Approval Program.
Environmental Review
As part of the Fuels Safety Program, Environmental Services helps ensure that a company’s actions to deal with a fuel leak or spill comply with proven and effective environmental requirements.
Learn more about TSSA’s Environmental Review.
Oil and Gas Pipeline Oversight Program
As part of TSSA’s transition to an Outcome-Based Regulator, TSSA has developed a risk-based Operator Rating System (ORS) for pipeline operators. The ORS is in line with best practices in other jurisdictions and focuses on reducing the risk of pipeline safety incidents.
