The police closed a 17-kilometer stretch of Highway 403 eastbound between Brantford and Ancaster on Friday, as officers investigated a pair of collisions involving motorcycles.

The police said one of the accidents was fatal. Conrad Vitalis stated that the first accident, a single-vehicle collision, occurred around 4 a.m. on Highway 403 eastbound near Garsville Road.

Vitalis said the motorcycle collided with the highway median. The rider was taken to the hospital with serious injuries. Shortly after, about 17 km away, a second collision occurred on Highway 403 eastbound and Wayne Gretzky Parkway in Brantford.

Vitalis said this involved a motorcycle and two vehicles, but the motorcycle rider was taken to the hospital and died from his injuries.

Highway 403 eastbound was reopened around 11:30 a.m., after being closed for nearly six hours. The cause of both accidents is still under investigation. It is not yet known if any charges will be filed.
