Orin Landscaping Inc. Pleads Guilty for Striking Gas Pipeline in Toronto
Second Guilty Plea This Year for Pipeline Strikes in Ontario
Toronto, ON, August 20, 2025 — Vaughan-based Orin Landscaping Inc. (Orin Landscaping) has pleaded guilty to striking and damaging a natural gas pipeline in Toronto and has been fined $30,000 and a 25% victim surcharge by the Ontario Court of Justice. The company was found guilty of an offence under Ontario Regulation 210/01 of the Technical Standards and Safety Act, 2000.
In December 2024, Orin Landscaping was using a mechanical excavator for a drainage installation project at Bathurst Street in downtown Toronto when it struck and damaged a 4-inch plastic gas main pipeline that was part of the Enbridge gas supply system. No injuries were reported in this incident.
By law, contractors must obtain locates before digging to avoid damaging pipelines and other underground infrastructure. Even with the legally required locates, Orin Landscape violated safety code requirements by using a mechanical excavator within one metre of the gas line. Only vacuum excavation equipment or hand tools is permitted within this distance, as specified by the safety code provision.
“Enforcement is one of our key tools to protect public safety as Ontario’s safety regulator. This marks the second guilty plea for gas pipeline strikes so far this year,” said Owen Kennedy, TSSA’s Director of Fuels. “Contractors must take every necessary precaution when digging near pipelines. Striking underground infrastructure doesn’t just disrupt the affected neighbourhoods; it can cause gas leaks and many other serious consequences. Follow rules and dig safe, that’s the right thing to do for every business involved in excavation,” added Mr. Kennedy.
In March 2025, another construction company was fined for damaging multiple gas lines in and around Ottawa, which caused gas outages for six homes and a retail mall. Pipeline strikes account for the vast majority of fuels incidents in Ontario, making up 70% of all reported fuels incidents in fiscal year 2024, according to TSSA’s latest Public Safety Report. Failing to follow safety requirements when digging can lead to serious risks, including gas leaks, fires, explosions, property damage, injuries, or fatalities. Additionally, repairs often require shutting off the gas supply, leaving nearby homes and businesses without heat, hot water, or cooking fuel.
Contractors must follow the safety code when digging. The requirements are set out in Canadian Standards Association’s Damage Prevention for the Protection of Underground Infrastructure safety code, CSA Z247-15.
Before any digging project, homeowners and contractors must contact Ontario One Call to locate underground infrastructure such as gas, hydro, cable, and phone lines. This is an important step to help reduce the risk of damaging pipelines and other buried services.
If a gas line is damaged or a leak is suspected, it must be reported immediately to the Ministry of the Environment’s Spills Action Centre at 1-800-268-6060 or TSSA at 1-877-682-8772.

Toronto, ON, July 2, 2025 – Magical Midways Inc. has pleaded guilty to one count of violating the Technical Standards and Safety Act, following a serious safety incident involving one of its amusement rides in Campbellford, Ontario. The Ontario Court has imposed a fine of $30,000, along with a 25% victim surcharge.
The incident occurred in August 2022 at the Campbellford Fair, where one of the cars became detached from the ride known as the Tilt-A-Whirl while in operation. At the time, the car was carrying three passengers and they all sustained minor injuries.
An investigation by the Technical Standards and Safety Authority (TSSA) revealed that Magical Midways Inc. failed to maintain proper inspection records in accordance with Ontario Regulation 221/01. The employee responsible for maintenance used a simplified checklist that did not reflect the manufacturer’s required procedures. The logbook lacked any documentation of the necessary inspection and testing of fasteners on the car’s pivot pin assembly – a failure that led to the unit's unexpected detachment.
“Maintenance is just as important as installation when it comes to amusement ride safety,” said AJ Kadirgamar, Director of TSSA’s Amusement Devices Safety Program. “Installation ensures a ride is set up for safe use, but ongoing maintenance ensures it remains safe over time. Overlooking key procedures or failing to document them can put users at serious risk.
Every detail matters in maintenance, and the purpose of the logbook is to record all safety actions carried out. As the regulator, we urge amusement device operators to devote the necessary attention and effort to this safety process designed to help protect both property and passengers.”
TSSA’s data show that failures in maintenance and record-keeping remain a key compliance issue in the amusement devices sector. According to TSSA’s latest Public Safety Report, the highest number of orders issued during periodic inspections of amusement devices in fiscal year 2024 — accounting for 7.69% of all orders — were related to operators’ failure to ensure that certified mechanics performed periodic maintenance and documented it in the associated log books.

Gerow Propane Ltd. Fined $80,000 For Safety Violation in Fatal Carbon Monoxide Incident
One fatality and seven injuries resulted from the poisonous gas exposure
Toronto, ON, March 20, 2025 – Brighton-based propane distributor, Gerow Propane Ltd., pleaded guilty yesterday to one count of an offence under the Technical Standards and Safety Act. The offence involved a fatal carbon monoxide exposure at a property in the Township of Hamilton, Ontario. The Ontario Court of Justice ordered Gerow Propane to pay a fine of $80,000, plus a 25 per cent victim surcharge.
Between December 16, 2020, and February 14, 2022, Gerow Propane supplied propane to fuel a boiler installed in the property’s garage for heating purposes. On February 14, 2022, a 57-year-old relative of the property owner was found deceased in the garage from carbon monoxide exposure. Additionally, seven other individuals at the scene, including five firefighters and two heating contractors, were injured by the poisonous gas and were hospitalized.
TSSA’s investigations revealed that the boiler released carbon monoxide into the indoor space, causing the poisonous exposure. The boiler had been built for use with natural gas but was found operating on propane as its fuel source. Without undergoing the necessary conversion, including the installation of a new orifice suited for propane, the boiler allowed products of combustion to leak.
Despite delivering propane to the property on seven occasions, Gerow Propane failed to comply with Ontario Regulation 211/01 prescribed under the Act, which requires propane suppliers to inspect appliances connected to propane to ensure their safe operation and attach a label confirming compliance with safety codes and requirements.
Owen Kennedy, Director of Fuels at the Technical Standards and Safety Authority (TSSA), said, “This is a tragic event caused by a serious non-compliance. Propane suppliers have a legal responsibility to ensure that fuel-burning devices are installed in compliance with the applicable codes and can be used safely. Any failure to verify this can lead to harmful consequences such as fires, carbon monoxide poisoning, and other hazards.”
Mr. Kennedy added, “For consumers, after installing a fuel-burning device in any indoor area, including those separate from your primary living space, it’s best to install a carbon monoxide alarm and have the heating equipment regularly inspected by a qualified fuel contractor. These precautions are important safeguards and could have been life-saving in this case.”

Thomas Cavanagh Construction Fined $100,000 for Gas Line Strikes in Ottawa
Toronto, ON, March 19, 2025 – Thomas Cavanagh Construction Limited (Cavanagh Construction) has been fined $100,000 after pleading guilty last week to five safety violations under the Technical Standards and Safety Act. Cavanagh Construction’s violations resulted in damage to multiple gas lines in and around Ottawa, causing gas outages for six homes and a retail mall. The Ontario Court of Justice also imposed a 25% victim surcharge.
Between March 28, 2023, and July 24, 2024, while under contract with the City of Ottawa for tunnel and pipeline upgrades, Cavanagh Construction caused 11 gas line breaks. The company had proper locates and maps identifying gas lines and was aware that regulations prohibit using mechanical excavators within one metre of a gas line. Despite this, Cavanagh Construction used mechanical excavators instead of the required hand digging or hydro excavation methods near pipelines, leading to breaks and gas supply disruptions for homes and businesses.
“Using heavy machinery for excavation near pipelines is unsafe, as reflected in our safety regulations, and this case has proven that,” said Owen Kennedy, Director of Fuels at the Technical Standards and Safety Authority (TSSA). “It is important to be cautious when digging because unsafe practices can put many people at risk of losing heat, hot water, and the ability to prepare meals. In the most serious cases, it can lead to explosions that cause property damage, injuries, or even loss of life.”
TSSA reminds individuals and businesses to contact Ontario One Call before digging to locate underground infrastructure, including gas, hydro, cable, and phone lines. Any damaged pipelines or gas leaks should be reported immediately to the Ministry of the Environment’s Spills Action Centre at 1-800-268-6060 or TSSA at 1-877-682-8772.

Toronto, ON, June 24, 2024 – Elevator contractor OTIS Canada Inc. has been found guilty to one count of performing work on an elevator in an unsafe manner, an offence under the Technical Standards and Safety Act Ontario Regulation 209/01: Elevating Devices. The safety violation caused injuries to two apprentice elevator mechanics employed by the company. The Ontario Court of Justice ordered OTIS Canada Inc. to pay a fine of $300,000, plus a 25 per cent victim surcharge.
In April 2023, OTIS Canada Inc. was the contractor responsible for installing new elevators in a nine-storey condominium under construction in Toronto, when two apprentice elevator mechanics employed by OTIS Canada Inc. were performing work on an almost completed elevator. The apprentice mechanics failed to properly counterbalance the elevator with appropriate weights. They were riding on the elevator when it plunged from the second floor to an underground car park level, causing significant injuries. One apprentice sustained bruises while the other suffered fractures to both feet. The fallen elevator was heavily damaged.
“This is one of the largest fines imposed on an elevator company in recent years, reflecting the seriousness of the contractor’s violation which caused significant harm,” said AJ Kadirgamar, Director of Elevating and Amusement Devices, TSSA. “Ensuring the safety of elevator workers is as critical as ensuring the safety of all riders. The elevator industry must prioritize maintaining a safe working environment for their employees and contractors.”

Robert Excavating Fined $15,000+ for Damaging Pipeline
Six homes evacuated, and 20 homes lost service
Toronto, ON, May 25, 2023 – Robert Excavating pled guilty last Thursday to damaging a pipeline, an offense under the Technical Standards and Safety Act. As a result of the damage, six Ottawa homes were evacuated, and 20 homes lost service. The Ontario Court of Justice ordered Robert Excavating to pay a total fine of $15,000, plus a 25 per cent victim surcharge.
In August 2021, Robert Excavating and its subcontractor were performing a water rehabilitation project. Robert Excavating’s subcontractor struck a two-inch polyethylene pipeline with a mechanical excavator, causing gas to escape. While valid locates were obtained and locate marks were made on site, the pipeline was not located by hand digging prior to the use of mechanical equipment. In addition, the subcontractor was excavating within the one metre boundary of the pipeline.
“Any excavation work must comply with Ontario’s safety laws, including obtaining a valid pipeline locate before breaking ground and not using mechanical equipment while digging within one metre of a pipeline,” said Sam Sadeghi, Statutory Director, Fuels Safety Program, TSSA. “The consequences of not abiding by these laws can be catastrophic, as puncturing a gas line can result in damage, explosions, injury and even death.”
TSSA reminds Ontarians to contact Ontario One Call at 1-800-400-2255 to have cables, wires, and pipes located before digging to avoid hitting underground facilities, such as gas, hydro, cable, and phone lines. Damaged pipelines and subsequent gas release should be reported immediately to the Ministry of Environment’s Spills Action Centre at 1-800-268-6060 or by contacting TSSA toll-free at 1-877-682-8772.

Individual Fined $5,000 for Activating Natural-Gas Pool Heater Without Certification, Resulting in Injury to Homeowner
Toronto, ON, May 25, 2023 – Jeffrey Payne, a plumber residing in Ottawa, pled guilty last Thursday to one count of activating a natural-gas pool heater without a TSSA-issued gas technician certificate, an offense under the Technical Standards and Safety Act. The Ontario Court of Justice ordered Payne to pay a $5,000 fine, plus 25 per cent victim surcharge.
In September 2022, Payne visited an Ottawa home and completed the installation of plumbing connected to a natural-gas pool heater. The propane gas supply line had already been connected to the pool heater prior to Payne’s visit. Payne then turned on the gas supply line to the pool heater. This was the first time that the gas supply line and pool heater were activated.
Later that day after Payne left the home, the homeowner turned the pool heater off and then on again. Upon restarting the pool heater, an explosion occurred, and the homeowner sustained burns to his left hand.
“It is essential that homeowners hire only registered contractors for the installation, activation, service and inspection of all fuel-fired appliances,” said Sam Sadeghi, Statutory Director, Fuels Safety Program, TSSA. “Improper servicing of a natural-gas appliance could lead to explosions, carbon monoxide poisoning and other safety risks that can sicken, injure or even kill unsuspecting residents.”
TSSA provides direct oversight of all of Ontario’s registered fuels contractors, which means a registered contractor’s work — and the work of the contractor’s certified technicians – is subject to TSSA audits for compliance with safety requirements.

Glover-Hill Inc. Fined $10,000+ for Employing Unlicensed Worker to Perform Boiler Maintenance at Healthcare Facility
Toronto, ON, May 3, 2023 – Glover-Hill Inc., an Ontario registered fuels contractor, pled guilty on Friday to one count of failing to take every reasonable precaution to ensure the company’s employees are appropriately certified to perform gas work, an offense under the Technical Standards and Safety Act. The Ontario Court of Justice ordered Glover-Hill Inc. to pay a total fine of $10,000, plus a 25 per cent victim surcharge.
Under Glover-Hill Inc.’s employment, an employee that did not hold a Technical Standards and Safety Authority (TSSA) gas technician certificate, was dispatched to a healthcare facility and installed a shut-off valve on a natural gas boiler. Glover-Hill Inc. was aware that the employee was a plumber and that the employee did not hold the required TSSA certificate.
“Improperly performed gas work is a significant safety risk that can lead to injury and even death to those in the vicinity,” said Sam Sadeghi, Director of TSSA’s Fuels Safety Program. “That’s why TSSA-registered contractors have a legal responsibility to ensure all of their employees are properly trained and certified to perform the work they are assigned. Those who fail to do so will be held accountable.”

Improperly Done Work Resulted in Homeowner Fainting from Carbon Monoxide Leak
March 28, 2023 – The Technical Standards and Safety Authority (TSSA) recently successfully prosecuted Zlatko Antonov of Jolanta Plumbing & Mechanical Inc. for altering exhaust venting on a natural gas boiler without holding a TSSA gas technician certificate. The improperly done work resulted in a carbon monoxide (CO) leak and injury to a homeowner.
Three days after Antonov performed the work at a Toronto residence, the homeowner fainted, and 911 was called. When the first responders arrived and detected a high CO reading, the home was evacuated, and the homeowner was taken to the hospital in an ambulance.
Antonov has never held a TSSA certificate and had a prior conviction for working without a certificate. Given the severe danger posed by Antonov’s unauthorized work and his previous conviction, the Ontario Court of Justice ordered Antonov to pay a $30,000 fine, plus a victim surcharge, within 180 days.
“A fine of this magnitude sends a clear message to Antonov and those participating in the underground market that performing fuels work without a TSSA certificate is a serious violation of Ontario’s public safety laws and will not be tolerated,” said Sam Sadeghi, Director of TSSA’s Fuels Safety Program.
TSSA reminds the public that all gas appliance work must be performed by a TSSA-certified technician who is employed by a TSSA-registered contractor. All Ontario contractors are listed on the TSSA website.

Individual Fined $6,000+ for Employing Unlicensed Worker to Install Natural Gas Water Heater
March 16, 2023 – Michael Daniel Hogan, sole director of Mike Hogan Plumbing and Heating Inc. in Kingston, pled guilty on Monday to one count of failing to take every reasonable precaution to ensure the company’s employees are appropriately certified to perform gas work, an offense under the Technical Standards and Safety Act. The Ontario Court of Justice ordered Hogan to pay a total fine of $6,000, plus a 25 per cent victim surcharge.
Under Hogan’s employment, an employee who has never held a T SSA certificate, licence, or registration, was dispatched to a Kingston home to install a natural gas water heater. Hogan, a TSSA-certified G2 gas technician, failed to ensure the employee was certified to perform the work he completed during the course of his employment.
Difference Between Certified Technicians and Registered Contractors
While certification refers to the legal obligation for an individual to have the necessary qualifications to perform gas work, registration describes the legal requirement that a company be registered and therefore permitted to perform gas work.
“Registered contractors are responsible for ensuring all of the technicians they hire are properly trained and certified by TSSA to perform the tasks they are assigned to code,” said Sam Sadeghi, Director of TSSA’s Fuels Safety Program. “If contractors or homeowners have any doubt of a technician’s qualifications, they are urged to call TSSA at 1-877-682-8772 to verify the validity and level of the technician’s certification.”
TSSA reminds the public to hire only registered contractors for the installation, service and inspection of a fuel-fired appliances. TSSA provides direct oversight of all of Ontario’s registered fuels contractors, which means a registered contractor’s work — and the work of the contractor’s technicians – is subject to TSSA audits for compliance with safety requirements.
