“As officers were responding (to the first collision), a secondary collision occurred” as people were standing outside their vehicles and were struck when another car crashed into the disabled vehicles, OPP Sgt. Kerry Schmidt said in a post to X.

Two people who were standing outside their vehicle were seriously injured and taken to hospital, police said.

“If you travelled in that area around that time and have dashcam footage” or witnessed the collision, Schmidt said, call police at 905-858-8670.
