Is there an evidentiary link between a medical assessment and the care recommended by an occupational therapist and rehabilitation consultant?

ICBC says that the trial judge did not examine each request and determine if there was an evidentiary link between the medical assessment and the care recommended by the occupational therapist and rehabilitation consultant. As Garson J.A. said in Gregory v. Insurance Corporation of British Columbia, 2011 BCCA 144, at para. 39: I do not consider it necessary, in order for a plaintiff to successfully advance a future cost of care claim, that a physician testify to the medical necessity of each and every item of care that is claimed. But there must be some evidentiary link drawn between the physician’s assessment of pain, disability, and recommended treatment and the care recommended by a qualified health care professional: Aberdeen at paras. 43, 63.
