TSSA is using the Client Portal to share important, sector‑specific safety information with liquid fuel licence holders who renew their licences online.
Beginning June 1, 2026, operators renewing liquid fuel facility licences through the Client Portal will see a safety message pop‑up. They can choose to read the message immediately or later via email before completing the renewal process.
The Client Portal provides a timely opportunity for TSSA to share critical safety information with liquid fuel facilities to help prevent incidents and support safer operations. We encourage licence holders to read the message and share it with their safety teams.
Operators also have the option to email the safety message to colleagues or individuals responsible for safety, helping to reinforce compliance obligations across their organization.
The safety message will appear only once per account, even if multiple facilities are associated with the same account.

Toronto, ON, May 25, 2026 – Repeat offender Mark Van Watteghem has been sentenced to 15 days in jail and fined $10,000 plus a victim surcharge by the Ontario Court of Justice after being found guilty of fuel safety violations under the Technical Standards and Safety Act.
Mr. Van Watteghem was convicted for the third time after removing a gas furnace and installing a replacement unit at a home in Windsor, Ontario. He was found performing this work without valid authorization by the Technical Standards and Safety Authority (TSSA). The fuel technician was previously convicted in 2016 and 2019 for unsafe fuel work and for performing fuel work as an unregistered contractor, receiving fines totalling $25,000 plus the victim surcharge.
“Mark Van Watteghem’s fuel work was deceitful and placed the lives of those who trusted him at serious risk,” said Owen Kennedy, Director of Fuels Safety at TSSA. “He has not been a registered contractor for 11 years and has been without a valid certificate for nine years. During that time, his work exposed customers to potentially fatal dangers, including carbon monoxide poisoning. TSSA supports the court’s decision to impose a stronger penalty in response to his repeated and fraudulent conduct.”
In Ontario, only fuel contractors registered with TSSA and individuals holding a valid gas technician certificate are legally permitted to work on fuel‑fired appliances. Before commissioning any fuel work, members of the public are encouraged to search for and verify registered contractors using TSSA’s online Authorized Heating Fuel Contractors Lookup Tool.

TORONTO, ON, April 21, 2026 - Spring showers may bring flowers but torrential downpours, milder temperatures and the thawing of some mass accumulations of snow across parts of Ontario could bring serious flooding threats and consequences. As the risks of seasonal flooding increase, so do the potential hazards related to fuel-burning equipment and elevators. Additionally, disruptions to major energy systems during floods may prompt people to use unsafe power generation alternatives. The Technical Standards and Safety Authority (TSSA) is reminding Ontarians to avoid taking unsafe actions, ‘fixes or alternatives.
Reduce the risks and potential of harm.
- Never use any fuel-burning appliances indoors that are specifically designed and approved for outdoor use only such as portable, fuel-fired generators, BBQs etc., as they can cause carbon monoxide poisoning, fires, and other dangers.
- Keep outdoor generators away from open windows, doors, and vents to prevent carbon monoxide from infiltrating living spaces.
- Avoid using portable fuel-burning devices like generators and propane BBQs in enclosed areas such as garages or covered patios, as this can lead to carbon monoxide buildup.
- Exercise caution when using commercial ventilating fans to dry out a basement, as this could create negative pressure, allowing carbon monoxide from household appliances to re-enter the home. Ensure proper ventilation during this process.
- Never use elevators in a flooded building as water can accumulate in elevator shafts or adversely affect an elevator's operation leading to entrapment or injury.
If you're unsure about the safety of a specific TSSA-regulated equipment or device during floods, contact TSSA for more information.

“CO is a leading cause of accidental poisonings in Ontario. That’s why it’s so important that residents do not compound a hazardous situation, such as a flood, by exposing themselves, families, friends and pets to potential CO risks. It’s critical that any fuel-burning appliances designed for outdoor use only, such as portable fuel generators or BBQs, remain just there – outside – to avoid the potential or CO poisoning, fires or other hazards.” Owen Kennedy, Director, Fuels Safety Program, TSSA
“In buildings impacted by flooding, the elevators can potentially be compromised. Water can accumulate in elevator shafts or adversely affect an elevator’s operation, creating a dangerous situation for passengers including entrapment or injury. It’s important to never use elevators in a flooded building or where there is any indication that water has leaked onto elevator components.” AJ Kadirgamar, Director, Elevating and Amusement Devices Safety Program, TSSA

TORONTO, ON, April 10, 2026 –– With the unprecedented snowfall accumulations this year, the spring season brings a welcome change as Ontarians dig out of one season and into another.
As April is designated ‘dig safe’ month, the Technical Standards and Safety Authority (TSSA) and Ontario One Call are taking the opportunity to remind Ontarians of the importance of obtaining a locate before initiating any landscape, construction or any other digging project.
Unsafe excavation practices can put many people at risk of losing essential services including but not limited to heat, hot water, electrical and telecommunications. In the most serious of cases, it can lead to potential explosions that can cause property damage, injuries, or even loss of life. During the spring and summer months, pipeline strikes typically increase more than two-fold due to excavations without the proper locate permissions from buried infrastructure owners.
Improper use of equipment such as a shovel, backhoe or other machinery can potentially damage underground infrastructure, leading to safety hazards or very dangerous or fatal consequences.
- Nicking a gas line could lead to leaks, fire, or explosions.
- Damaging electrical cables could shock or electrocute you.
- Hitting water or sewer lines could cause flying debris, floods, contamination, and environmental hazards.
- Cutting telecommunications cables could disrupt internet or cable services and your ability to call 911 in an emergency.
BEFORE starting any landscaping, construction, or other digging project, a locate request must be submitted at ontarioonecall.ca. This notifies underground utility owners so they can mark the location of buried infrastructure such as gas, hydro, and communication lines.
It's free, it's easy, it's the law.
- If you are planning a digging project, you must submit a locate request at ontarioonecall.ca at least five business days before you start for a single property project and 10 business days for projects involving multiple properties or areas without a civic address.
- If you have hired a contractor, make sure your contractor has contacted Ontario One Call before they start your project.
- Check the paperwork emailed to you by the utility owners to ensure it covers your dig and make sure you understand all the markings - if not, contact the utility owner.
- If you accidentally strike any underground services (e.g. pipelines, electrical lines, cables, etc.), immediately call 911 and all associated service providers.
