Six people were taken to hospital following an explosion at a manufacturing plant in the community of Newmarket, north of Toronto, on Wednesday.

The company, Dortec Industries, a manufacturing division of Magna Closures, said the blast was due to a minor electrical explosion that was isolated to one manufacturing line.

The explosion occurred at the Dortec plant on 581 Newpark Blvd. just before 10 a.m., Central York Fire Services said. About 200 people work at the plant, which was evacuated.

Three other people received minor injuries that did not require hospital treatment. A spokesperson for Southlake Regional Health Care hospital in Newmarket said all six people admitted were in stable condition.

According to a statement by Magna, all six patients have been released from hospital.

Five fire crews responded to the call. The Ontario Ministry of Labour and the fire marshal's office in York Region were on scene to investigate.

A statement from Magna released Wednesday afternoon said there was no damage to any equipment or structural damage to the building. Operations will resume as normal.

The facility produces door latches and door modules.
