A serious collision closed Regional Road 25 between Louis St. Laurent and Britannia Road yesterday afternoon.
Police say a northbound orange Dodge collided with a stopped Honda Civic, propelling the Civic into the path of an oncoming white van.
The driver of the Honda Civic, a 34-year-old Oakville man, was transported to a trauma centre in critical condition.
The driver of the Dodge, a 22-year-old Milton man, received minor injuries while the driver of the van and his two passengers were uninjured in the collision.
The Collision Reconstruction Unit attended the scene and took over the investigation.
Police do not believe impairment or the weather were factors in the collision.
