One person is dead and another is seriously injured after a head-on crash north of Alliston.
The OPP says a Pontiac Sunfire travelling on Scotch Line on Thursday collided with a Honda Civic just after 9 a.m.
The 43-year-old man driving the Sunfire was pronounced dead at the scene. A female passenger was airlifted to a Toronto hospital, where she remains in critical condition.
The driver of the Honda was taken to an Alliston hospital with non-life threatening injuries.
Scotch Line has since reopened.
