One electrical worker died and another was hospitalized after a TTC bus struck their truck Thursday night.

The two Stacey Electric workers were doing spot maintenance at an underpass on Bathurst Street north of Dupont Thursday evening when a bus in the passing lane struck their vehicle in the curb lane.

The 51-year-old man who was in the basket of the truck's cherry picker -- which was positioned above the road -- was thrown out in the collision. He suffered non-life threatening injuries.

The other worker, a 42-year-old man, was on the ground when he was hit and killed by the bus.

"He was the spotter underneath the bucket in the centre of the lane," Const. Hugh Smith of the Toronto Police Service's traffic unit told reporters at the scene.

The bus had been engaged in a collision avoidance manoeuvre when it struck the ground-level worker, he said.

TTC spokesperson Brad Ross said: "We have almost 2,000 vehicles on the road every day. They're big vehicles. They can't stop with precision as a small car could."

Other workers from Stacey Electric took the place of the two on Friday to finish the work, but they were protected by orange pylons and a police officer.

Police are asking anyone with information to contact them.

The incident is the latest in a recent string of transit-related crashes already being investigated by the Toronto Transit Commission.

On Saturday, a 66-year-old man died from injuries sustained when TTC bus hit him as he crossed Danforth Road near St. Clair Avenue East.

The TTC is also probing three other incidents involving their vehicles last week, including the collision of a Greyhound bus and a streetcar that sent 17 people to hospital.
