Investigators had originally said the device exploded Monday morning, but have since clarified that the blast actually happened around 2 a.m. on Sunday.
It damaged the undercarriage of the empty vehicle, tore rubber off the rear wheels, scorched the driveway and hurled bits of metal across several properties.
Sgt. Peter Thiessen says the blast was strong enough to drive shrapnel through the walls of two neighbouring garages with enough velocity to tear through the opposite side of one the buildings.
No one was hurt.
Thiessen says a motive for the violence is not clear and anyone with information is urged to contact police.
