A man in his 40s has died after an explosion at an industrial lab in Dorval, Que., late Friday morning.
The man died before he could be sent to hospital. At least three other people were also injured, the ambulance service covering Montreal and Laval said.
Emergency services responded to a call at around 11:30 a.m and rushed to the Polymer Source research centre on Avro Street in Dorval's industrial park.
Paramedics rushed two people to hospital, one with an injury to the upper body and another with a "medical" injury. One woman suffered less serious injuries, Urgences-santé said.
The lab is home to a large chemical laboratory supplying research grade polymers to scientists, according to its website.
Two inspectors from Quebec's workplace safety board, the CNESST, have secured the site and are investigating the cause of the explosion.
More to come.
