A man is in critical condition in a Calgary hospital after his tractor-trailer rolled over while navigating a tight corner in Glacier National Park on Friday.
The crash happened on a sharp curve on the Trans-Canada Highway near the Illecillewaet Campground on June 15 just before 8 p.m.
The westbound truck was travelling from Winnipeg to Delta, B.C., when it rolled over.
The driver was airlifted to Foothills Hospital in Calgary where he is in critical condition and the passenger was taken to hospital in Golden with minor injuries.
The accident is being investigated and RCMP is looking at speed, driver inattention and inexperience; and load configuration as potential causes of the crash.
Sgt. Mike Pears of the Trans Canada East Traffic Services said crashes like this are preventable if drivers slow down and pay attention.
"This corner did not just show up," he said.
