A chemical leak from a factory in the Chemical Court and Coronation Drive area temporarily shut down the Scarborough industrial zone yesterday morning.

The leak, reported around 11:05 a.m., created a cloud of sulphuric acid vapour, said Toronto fire Capt. Mike Strapko.

An 8 km/h wind carried a chemical odour northeast of the leak location, he added.

Businesses in the surrounding area were evacuated.

“We requested three TTC buses to shelter people in. They were moving people who are in the affected area onto Coronation Street,” Strapko said.

Sulphuric acid is described as highly corrosive and toxic, Toronto police Const. Wendy Drummond said. However, no injuries were reported.

The TTC later resumed regular service on the 86D Scarborough and 54A Lawrence buses, which had been temporarily diverted due to the leak.
