Saskatoon fire investigators say the cause of a blaze in the North Corman Industrial Park Friday night is undetermined but caused around $200,000 in damage.
Crews were called to the truck yard around 11:15 p.m. when people saw heavy smoke and flames.
When crews arrived they found two tractor-trailer units engulfed in flames.
The fire was quickly brought under control and did not spread to nearby equipment or buildings.
There were no injuries.
