I INTRODUCTION

Collateral benefits are gains that flow to a plaintiff after a defendant's wrong (aside from the damages being claimed against the defendant) that the plaintiff would not have received but for the wrong. (1) Where a plaintiff receives a collateral benefit, there may be a concern that the awarding of damages for the full amount of the plaintiff's loss could result in excess compensation for the plaintiff. As a result, the court must determine whether to deduct the amount of the collateral benefit from the award for damages.

Although it is commonplace for plaintiffs to receive various sorts of benefits prior to trial, Canadian courts have failed to adopt a clear, coherent test for determining the deductibility of collateral benefits. Currently, the courts will hold a benefit to be non-deductible if it is sufficiently similar to one of two established types of non-deductible benefits: insurance payments and gifts. (2) This analysis by analogy is hampered by judicial disagreement regarding the appropriate rationale for allowing plaintiffs to retain these types of benefits. In the leading case of IBM Canada Ltd v Waterman, the Supreme Court of Canada listed several general propositions in relation to deductibility drawn from case law, but declined to articulate a singular principle to explain deductibility. (3)

Due to the unsettled state of the law, collateral benefits cases are highly unpredictable. As the Supreme Court suggested in Waterman, there remains a need for an "applicable rule [that] is clear, coherent and easy to apply". (4)

This paper argues that the "causal rationale" should be adopted as the guiding principle for collateral benefit problems. According to the causal rationale, the courts should ignore a collateral benefit when calculating damages where the true cause of the benefit is not the defendant's wrong, but some independent cause. …
