The defendant, Shawn Norris, was charged with dangerous driving causing bodily harm and death, and impaired driving causing bodily harm and death, following a head-on collision.
The court found the defendant's driving objectively dangerous and a marked departure from a reasonable standard of care, considering his erratic driving over several kilometers, including crossing a median and swerving into oncoming traffic.
Despite arguments of tire deflation or a sudden physical event, the court found no evidentiary support for these.
The court also found the defendant's ability to drive was impaired by a combination of voluntarily consumed drugs (methadone, lorazepam, trazadone, venlafaxine), noting he "double dosed" on methadone and took unprescribed Lorazepam, and was aware of the drugs' potential impairing effects.
The court concluded that the only reasonable inference for the driving was drug impairment and that the mens rea presumption was not rebutted.
