Reasonable Foreseeability: Principles Regarding Whether an Advance Risk of Harm Arising Could Be Recognized
Question: What does “reasonable foreseeability” mean in Canadian negligence law, and how do courts assess whether harm was too remote?
Answer: In Canadian negligence law, “reasonable foreseeability” is an objective test asking whether a reasonable person in the defendant’s position should have anticipated a real risk of the type of harm that occurred, without relying on hindsight, and the remoteness analysis considers whether the harm is too unrelated to the wrongful conduct to impose fair liability, as discussed in Rankin (Rankin’s Garage & Sales) v. J.J., [2018] 1 S.C.R. 587 and Mustapha v. Culligan of Canada Ltd., [2008] 2 S.C.R. 114.

Understanding Foreseeability Principles
Negligence law includes the principle of reasonable foreseeability. Reasonable foreseeability involves the question of whether a reasonable person could envision the risk of harm arising from the specific conduct in question. As a fundamental component of negligence law principles requires an analysis of what a reasonable person would do or avoid doing, analyzing what a reasonable person would view as risky becomes necessary within a negligence liability discussion.
The Law
In the cases of Rankin (Rankin’s Garage & Sales) v. J.J., [2018] 1 S.C.R. 587, as well as Mustapha v. Culligan of Canada Ltd., [2008] 2 S.C.R. 114, the Supreme Court explained the concept of reasonable foreseeability and remoteness whereas it was said:
[53] Whether or not something is “reasonably foreseeable” is an objective test. The analysis is focussed on whether someone in the defendant’s position ought reasonably to have foreseen the harm rather than whether the specific defendant did. Courts should be vigilant in ensuring that the analysis is not clouded by the fact that the event in question actually did occur. The question is properly focussed on whether foreseeability was present prior to the incident occurring and not with the aid of 20/20 hindsight: L. N. Klar and C.S.G. Jefferies, Tort Law (6th ed. 2017), at p. 212.
[12] The remoteness inquiry asks whether “the harm [is] too unrelated to the wrongful conduct to hold the defendant fairly liable” (Linden and Feldthusen, at p. 360). Since The Wagon Mound (No. 1), the principle has been that “it is the foresight of the reasonable man which alone can determine responsibility” (Overseas Tankship (U.K.) Ltd. v. Morts Dock & Engineering Co., [1961] A.C. 388 (P.C.), at p. 424).
[13] Much has been written on how probable or likely a harm needs to be in order to be considered reasonably foreseeable. The parties raise the question of whether a reasonably foreseeable harm is one whose occurrence is probable or merely possible. In my view, these terms are misleading. Any harm which has actually occurred is “possible”; it is therefore clear that possibility alone does not provide a meaningful standard for the application of reasonable foreseeability. The degree of probability that would satisfy the reasonable foreseeability requirement was described in The Wagon Mound (No. 2) as a “real risk”, i.e. “one which would occur to the mind of a reasonable man in the position of the defendan[t] . . . and which he would not brush aside as far-fetched” (Overseas Tankship (U.K.) Ltd. v. Miller Steamship Co. Pty., [1967] A.C. 617 (P.C.), at p. 643).
[14] The remoteness inquiry depends not only upon the degree of probability required to meet the reasonable foreseeability requirement, but also upon whether or not the plaintiff is considered objectively or subjectively. One of the questions that arose in this case was whether, in judging whether the personal injury was foreseeable, one looks at a person of “ordinary fortitude” or at a particular plaintiff with his or her particular vulnerabilities. This question may be acute in claims for mental injury, since there is a wide variation in how particular people respond to particular stressors. The law has consistently held — albeit within the duty of care analysis — that the question is what a person of ordinary fortitude would suffer: see White v. Chief Constable of South Yorkshire Police, [1998] 3 W.L.R. 1509 (H.L.); Devji v. Burnaby (District) (1999), 180 D.L.R. (4th) 205, 1999 BCCA 599; Vanek. As stated in White, at p. 1512: “The law expects reasonable fortitude and robustness of its citizens and will not impose liability for the exceptional frailty of certain individuals.”
As per Rankin and Mustapha, foreseeability involves the question of whether a person could rationally anticipate that certain actions might bring about harm to another person. Furthermore, following the guidance of Rankin and Mustapha cases, while evaluating whether harm was foreseeable, a court should approach the question from a retro-active yet forward-looking perspective instead of looking back perspective after an incident has actually occurred..
Conclusion
Negligence law involves the review of whether a person acted carelessly and should be held liable for harm caused through such carelessness to another person. As part of the question of whether conduct was careless, the question arises as to whether the resulting harm was foreseeable. If the harm was reasonably unforeseeable, then liability for the harm fails to arise.
