A cab driver and two passengers narrowly escaped serious injury after four storeys of scaffolding fell onto a taxi in downtown Toronto on Tuesday afternoon.

The incident occurred at 117 Peter St., just south of Richmond Street West, at around 3 p.m., as the taxi was driving along Richmond.

“I’m feeling a little bit shaken, but I’m OK 100 per cent,” said taxi driver Ali Jamahersi.

He said he heard shouts and a loud boom when the two sets of four-storey scaffolding toppled and hit his car.

One tower hit the trunk of the cab and damaged the back window. No injuries were reported.

Crews at the site said a worker who was putting up scaffolding fell when it buckled, but he too was unscathed.

Jamahersi said he will take the next few days off in order to relax.

Officials from Ontario's Ministry of Labour were at the scene and continue to investigate.
