Mike Jefferies was driving his Yamaha motorcycle Saturday afternoon when it collided with a minivan in front of the St. Laurent Shopping Centre. He was found in cardiac arrest when paramedics arrived and was later pronounced dead at hospital.

Jefferies' wife Sandra, 53, was also on the bike when it crashed and suffered multi-system trauma. She was released from hospital soon after.

Both the motorcycle and the Dodge Caravan involved in the collision were headed southbound on St. Laurent Boulevard near the OC Transpo Transitway.
