One person was airlifted to hospital after a collision involving an ATV and a cargo van southwest of Mt. Elgin, Ont.

Oxford County OPP were called to the scene at Culloden Line and Daniel Road around 11:40 a.m. Thursday for the crash.

According to investigators, the cargo van was northbound on Culloden when it collided with the ATV, which was eastbound on Daniel.

Police say the 40-year-old male ATV operator was ejected in the crash and suffered life-threatening injuries.

An Ornge air ambulance was called in to transport him to hospital where he remains in critical condition.

For much of the day Culloden Line was closed between Prouse Road and Mt. Elgin Road while Daniel Road was closed between Dereham Line and Pigram Road.

Both roads have since reopened.

Daniel Road is controlled by stop signs for east and westbound traffic.

The investigation is ongoing and any witnesses are asked to contact police.
