The Technical Standards and Safety Authority (TSSA) is committed to supporting Ontario's transition to a low-carbon hydrogen economy through enhanced regulation of hydrogen distribution and utilization in the province.
Currently, TSSA regulates key areas of hydrogen infrastructure, including refueling station design, pipeline installation, and high-pressure piping. To ensure continued safety and effectiveness, TSSA is updating its licensing, inspection, contractor registration and training processes for hydrogen. These enhancements to the regulatory framework are aimed at supporting the safe adoption of hydrogen technology and foster the growth of the hydrogen sector in Ontario.
Effective February 3, 2025, key enhancements for hydrogen safety include the following:
- Licensing Requirements to Transport Compressed Hydrogen in Bulk Containers: Transport trucks that currently use bulk containers to transport compressed hydrogen to user locations will transition from variance approvals, when expired, to a licence application and approval process. Application for approval can be submitted through TSSA’s Client Portal.
- Licensing Requirements for Existing Hydrogen Facilities: Existing hydrogen facilities and equipment, including refueling stations and maintenance and conversion centres, will transition to ongoing inspections and licensing by TSSA. Establishing consistent inspection touchpoints will help ensure that all hydrogen facilities operate safely and comply with regulations.
- Licensing of New and Modified Hydrogen Facilities: All new and modified hydrogen facilities require TSSA’s engineering approval and inspections before being issued a licence to operate. Licences must be renewed annually. TSSA has published new guidelines on our website to facilitate the application for engineering approval.
Hydrogen Contractor Registration: A specific hydrogen contractor registration is now required of businesses that work on hydrogen systems and equipment in Ontario. As with other fuels contractors, hydrogen contractors will be regularly audited and must meet specific requirements for certification, equipment installation, and incident reporting.
Additionally, TSSA continues to offer certification for technicians who install, inspect, or repair hydrogen equipment. To support workforce development and build strong industry expertise, TSSA has designed a specialized hydrogen curriculum. TSSA invites interested education institutions to apply to become accredited training partners in hydrogen. Institutions can contact TSSA for more information about the curriculum and additional details.
