The Supreme Court takes another stab at the application of the "material contribution" test: Clements v. Clements and the law of proof of causation in negligence

By: Julia Vizzaccaro and Belinda Bain

Introduction

When seeking to recover damages in connection with harm resulting from another's negligence, an injured party must establish on a balance of probabilities that the tortfeasor caused the injury in question. The requirement that an injured party establish a causal connection between the negligent act and the resulting harm has been recognized to anchor the law of negligence to one of its underlying purposes, that of corrective justice.

The long standing test applied by the Canadian Courts to the proof of causation is the "but for" test.  Applied in both single cause as well as multi-cause injuries, the test requires the plaintiff to demonstrate that "but for" the defendant's negligent act, the injury would not have occurred.  However, the Supreme Court of Canada has ruled in the past that in certain exceptional circumstances, a Court may apply the "material contribution" test in place of the "but for" test. The "material contribution" test allows an injured party to avoid the need to prove "but for" causation and only requires proof that the negligent action materially contributed to the risk of harm.

In the case of Clements v. Clements 2012 SCC 32 ("Clements"), the Supreme Court on the one hand narrowed the application of the "material contribution" test, but in obiter comments, suggested that the test's application may be expanded in the future.
