Police are appealing for witnesses to a shocking crash on the M1 at the weekend which claimed the lives of a father and son from Toronto.

The 46-year-old man and 14-year-old boy were in a black Holden Commodore which became bogged on the median strip and Ourimbah at about 9.00am on Saturday in pouring rain.

A short time later, a white Mitsubishi SUV lost control and crashed into the car, killing the pair.

The driver of the SUV, a 27-year-old man, wasn’t injured and underwent mandatory testing at Wyong Hospital.

Police want to speak to motorists with dashcam footage who were at the location between 8.15am and 9am on Saturday.
