The applicant sought medical benefits for chiropractic treatment and physiotherapy following a motor vehicle accident.

The insurer denied the treatment plans, arguing the applicant had reached maximum medical recovery and that further passive modalities were not reasonable and necessary.

The Licence Appeal Tribunal agreed with the insurer, finding that the applicant had returned to a high degree of pre-accident function and failed to provide clinical evidence showing the proposed treatments would be effective in reducing her pain or impairment.

The appeal was dismissed.

In this personal injury trial arising from a motor vehicle accident, the court addressed an objection to proposed opinion evidence from a treating chiropractor on whether the plaintiff still required treatment.

Applying the framework for participant experts, the court held that treating health practitioners may give opinion evidence without rule 53.03 compliance only if the opinion was formed through observation or participation in the events at issue in the ordinary exercise of their expertise.

The court further held that a party should disclose in advance opinions to be elicited from a participant expert when those opinions are not contained in the records already produced.

A voir dire was ordered on admissibility, and any resulting prejudice was addressed by permitting the defence orthopedic expert to respond without full rule 53.03 formalities.
