The applicant was injured in a motor vehicle accident and sought statutory accident benefits.

She had a rare, pre-existing brainstem cavernoma that was symptomatic prior to the accident.

The insurer argued the post-accident deterioration was the natural progression of her condition.

The arbitrator found that the applicant did not suffer pre-accident loss of consciousness and accepted the applicant's expert evidence that the torsional force of the collision likely caused increased bleeding in the cavernoma.

The arbitrator concluded that the accident materially contributed to the impairment, tipping the balance from a mild impairment to a life-threatening condition.

The applicant was found severely injured in a driveway between two houses with no memory of the incident.

He claimed statutory accident benefits, alleging he was struck by a motor vehicle.

The insurer denied the claim, arguing the injuries resulted from an assault.

After hearing extensive medical expert testimony regarding the pattern and severity of the injuries, the arbitrator concluded on a balance of probabilities that the injuries were consistent with a pedestrian-automobile collision and ruled that the applicant was involved in an 'accident' under the Schedule.
