The 2003 Etobicoke gas explosion was a disaster which occurred on April 24, 2003, after a backhoe operated by Enbridge contractor Precision Utility breached a pipeline on Bloor Street in the Etobicoke district of Toronto, Ontario. The resulting explosion destroyed a two-story mixed commercial and residential building, killing seven people and injuring another four. Enbridge and several other companies were fined for the disaster in 2011.[1] A memorial garden was dedicated at the site of the explosion in 2008.[2]
On April 24, 2003, road work was being conducted to fix flooding concerns.[3] Enbridge contracted Precision Utility to locate natural gas pipelines along Bloor Street, west of Kipling Avenue. A pipeline leading into a plaza was not identified and an employee struck the pipeline with a backhoe,[1] causing natural gas to leak into the basement of a two-story strip mall with businesses and residential housing.[4] The workers immediately noticed the error and went to their vehicles to obtain tools to fix the leak.[3]
Explosion
At around 1:30pm,[2] the gas leaking out from the pipeline ignited, destroying the strip mall and damaging nearby buildings.[3] The explosion also caused a fire which also damaged an adjacent house. 100 people and 25 fire trucks were used to extinguish the fire. Windows in stores across the street were blown out, windshields were damaged on cars and one vehicle was destroyed.[3]
Seven people were killed in the explosion. Robert Fairley was a resident of the building while Adele Brown, Elizabeth Roy and Lillian Guglietti were clients at a salon in the strip mall. Dora Carambelas, Tina Kirkimtzis, and Irene Miyama were also in the building when it exploded.[2] Four people were also injured by falling debris.[3]
After Hurricane Hazel, this explosion was the second-highest loss of life for a single event in Etobicoke. This is also the highest loss of life for an incident involving a pipeline in Canadian history.[5]
Outcome
In April 2004, charges were laid concerning this incident but were dismissed in 2007. The dismissal was appealed and the case was reconsidered in 2011.[1] Warren Bitulithic Limited pled guilty to one charge under the Technical Standards and Safety Act in 2006.[4] The charge was for damaging a natural gas pipeline without permission.[2] The company was fined $225 000.[1]
Enbridge pled guilty to one charge under the Ontario Occupational Health and Safety Act and fined $350 000. They also pled guilty to another charge under the Technical Standards and Safety Act, requiring Enbridge to pay another $350 000 fine. The charges were for not evacuating gas services and not locating and marking the gas services before excavation. Four additional charges placed against Enbridge were withdrawn. Precision Utility pled guilty and was fined $200 000 for not properly supervising an employee while they were locating the natural gas lines.[1] An investigation by the Ministry of Labour found that the Precision employee did not use locate the pipelines by using available information and did not act when they should have noticed the presence of natural gas.[5] Each fine included a victim surcharge where an additional 25% of their fines would be paid to help the victims of this incident.[1]
By 2011 townhouses had been built on the site of the explosion. Milano’s Pizza, one of the businesses in the strip-mall, reopened across the street.[4] Peter Roy, the son of Elizabeth Roy, campaigned for gas companies to regularly install excess flow valves on pipelines to protect against runaway gas and high flow rates. He reported that Enbridge has begun doing this on their projects. Volunteers also established a scholarship for a student attending Humber College who is going to have a job in the gas sector.[2]
Five years after the explosion, a memorial plaque, garden and two benches were placed at the site of the explosion during a memorial service. The service was organised by then-Toronto City Councillor Peter Milczyn.[2]

Enbridge owns and operates pipelines throughout Canada and the United States, transporting crude oil, natural gas, and natural gas liquids, and also generates renewable energy. Enbridge's pipeline system is the longest in North America and the largest oil export pipeline network in the world. Its crude oil system consists of 28,661 kilometres of pipelines. Its 38,300 kilometre natural gas pipeline system connects multiple Canadian provinces, several US states, and the Gulf of Mexico. The company was formed by Imperial Oil in 1949 as the Interprovincial Pipe Line Company Limited to transport Alberta oil to refineries. Over time, it has grown through acquisition of other existing pipeline companies and the expansion of their projects.
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.
East Tennessee Natural Gas Pipeline is a natural gas pipeline that brings gas from eastern Tennessee to Virginia and North Carolina. It was formerly owned by Duke Energy but is now owned by Enbridge. Its FERC code is 2.
