The Ministry of Labour is still trying to find out how a construction worker was killed in Stoney Creek last week. 100 feet underground and another 100 feet into the tunnel, the man was reportedly pinned under a piece of construction equipment.

The company holding the contract to the project has not just one but two serious workplace incidents in the past, including a fatality.

According to their website, McNally Construction is Canada’s leading tunnel contractor but they were fined for a similar fatal incident just 7 years ago in Brampton during a tunnel excavation for sewage lines.

23 year old Onil Arcia was underground operating a battery powered locomotive and ended up crushing his head. The Ministry of Labour investigated and McNally Construction pleaded guilty to failing to take every precaution reasonable in the circumstances for the protection of a worker.

The jury at an inquest 4 years after Arcia’s death found that quote “it was unclear that operators had been properly trained in the safe usage of the locomotive.”

McNally Construction was fined $170 000 for a violation of the occupational health and safety act.

Then in Mississauga in 2015 another incident involving two locomotives colliding underground in a tunnel at a water project site. One worker was airlifted to hospital fighting for their life but luckily survived.

The sewer project underway heading towards Binbrook has been halted for now. The coroners office says a mandatory inquest will be conducted as soon as the ministry wraps up the investigation.
