Police say a 79-year-old London man is in critical condition following a collision north of London Tuesday evening.

At 6:24 p.m. emergency crews responded to Adelaide St. North and Ilderton Road after a grey Hyundai collided with a black Toyota SUV.

The elderly male was the driver of the grey car and was taken to hospital where he remains in critical condition.

A 16-year-old female from Bluewater Ontario, and a 45-year-old female from Strathroy sustained non-life threatening injuries and have been released from hospital.

Police are continuing to investigate and have not said if charges are pending.
