Police were called to the scene Monday night around 10:30pm after a 911 call was made by a man, known to police, threatening to detonate a bomb inside his car.

They shut down the highway in both directions near Canada's Wonderland in Vaughan. The York Region Emergency Response Unit and also the Toronto police Emergency Task Force bomb squad arrived on the scene. A robot was used to approach the car.

The man was arrested about three hours later after he gave himself up. His car was seized and the highway was reopened.

My husband was among those stuck on the highway heading North from 10:30pm until 1:30am when he called to say King's Road off-ramp was now opened after the man surrendered to police around 1 a.m.
