A vehicle collision knocked down hydro poles and caused power lines to land on a school bus Monday afternoon. Fire officials say none of the children on the bus were injured.

Crews were called to Keewatin Street and Manitoba Avenue shortly before 1 p.m. and determined the lines were not live hydro wires and the children, four kindergarten students, were all safe.

A vehicle had run into a hydro pole, knocking down the wires onto the bus and pulling down a second pole.

"Out of nowhere this guy comes flying right at me…so I swerved into the right lane, and he comes whipping by me," says Conroy Finnigan, who witnessed the crash. "I just looked in my rear view mirror right away… the guy goes flying into a pole, sparks came down."

A male driver was removed from his vehicle, which had rolled over, using the Jaws of Life. He was taken to hospital and is now listed in stable condition, say officials.

The bus was not involved in the initial vehicle crash.

Fire officials credit the school bus driver with doing the right thing by keeping the children inside the bus until crews arrived and determined it was safe for them to leave.

Tires act as an insulator and can protect against electrocution in the event of a vehicle coming into contact with live hydro lines, say fire officials.

Police closed Keewatin Street, both northbound and southbound, at Manitoba Avenue while crews were on scene.

Officers aren't saying whether or not charges are pending in connection to the crash.
