Two men were taken to hospital after a rollover in Niagara-On-The-Lake.

Emergency crews were called to the area of Carlton and Townline Road just before seven Sunday night.

Both the 22-year old driver from Grimsby and his 29-year old passenger from Lincoln suffered critical injuries.

The driver had to be extricated by firefighters and after being assessed at hospital in St. Cathrines, was air lifted to Hamilton General Hospital.

No names have been released as police continue to investigate.
