A cow is said to be the cause of a crash on Highway 400 Thursday night.
Crews were called to the southbound lanes of Highway 400, north of Highway 89, shortly after 9 pm after a cow was spotted running along the shoulder of the highway, entering one of the lanes.
According to Innisfil Fire officials, two vehicles collided while trying to avoid hitting the cow, which sent one car into the ditch.
One person was taken to hospital with minor injuries.
One lane was blocked as crews searched for the cow, but it was not located.
