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.
