What is the current state of the law in Canada regarding the duty of care of a person of ordinary fortitude under the Vanek Act?

[15] As the Court of Appeal found, at para. 49, the requirement that a mental injury would occur in a person of ordinary fortitude, set out in Vanek, at paras. 59-61, is inherent in the notion of foreseeability. This is true whether one considers foreseeability at the remoteness or at the duty of care stage. As stated in Tame v. New South Wales (2002), 211 C.L.R. 317, [2002] HCA 35, per Gleeson C.J., this “is a way of expressing the idea that there are some people with such a degree of susceptibility to psychiatric injury that it is ordinarily unreasonable to require strangers to have in contemplation the possibility of harm to them, or to expect strangers to take care to avoid such harm” (para. 16). To put it another way, unusual or extreme reactions to events caused by negligence are imaginable but not reasonably foreseeable.
