Aviva Canada Inc. v. Pastore, 2012 ONCA 642 (C.A.)
The insured was injured in a 2002 motor vehicle accident as a pedestrian and sustained an ankle injury. She alleged her gait had been altered and was diagnosed with a pain disorder. A DAC found her to be catastrophically impaired in 2005 due to a marked mental or behavioural impairment under s. 2(1.1)(g) of the SABS. An assessment under s. 2(1.1)(g) is carried out with reference to the AMA Guides, which provide for an assessment of function in four categories:
(1) Activities of daily living (ADL);
(2) Social functioning;
(3) Concentration, persistence and pace; and
(4) Deterioration or decompensation in work or work-like settings.
Pastore was diagnosed with a number of psychological disorders and the DAC concluded that she had a class 4 marked impairment in activities of daily living. The DAC concluded she was catastrophically impaired on the basis of the one class 4 impairment. The insurer did not agree with the assessment and the matter proceeded to mediation then arbitration.
At arbitration, the arbitrator agreed with the DAC assessors and held that one marked impairment was enough to comply with the Guides approach to impairment. In addition, it was appropriate to consider physical pain in assessing mental disorder, as it was not possible to factor out all physically based pain since it was intertwined with mentally based pain. The Director's Delegate upheld the decision, but the Divisional Court overturned the arbitrator.
The Court of Appeal allowed the appeal and reinstated the arbitrator`s decision. The conclusion that only one marked impairment is sufficient to meet the definition of catastrophic impairment was a reasonable one. In addition, it was not an error for the DAC assessors to consider both physical and mental pain.
Pastore appears to have lowered the bar for catastrophic impairment based on a mental disorder and more claimants may be able to fit themselves into a catastrophic designation than prior to this decision.
