(CNN) -- Bus passengers in Toronto were trapped briefly Monday after a falling crane knocked over electrical poles, sending live power lines onto the bus, a police spokesman said.
The fallen wires also draped over the crane, whose operator was taken to the hospital because of significant shoulder bruises, said Stephan Powell, a district chief of Toronto Fire Services.
The crane operator had no broken bones, Powell said.
The Toronto Transit Bus was carrying 23 passengers, he said.
There were no major injuries in the "industrial accident," which happened at a construction site about 1:20 p.m. ET, Constable Victor Kwong said.
Passengers and the driver were able to move to safety just after 2 p.m.
Three power poles were knocked down during the incident. Video showed one of the power poles just behind the rear end of the bus, which was in the right lane of a four-lane road.
