In Carter v. Ford Motor Company of Canada¹ (Carter), the Ontario Superior Court of Justice struck portions of a lawyer's affidavit that summarized and attached as exhibits various unverified online complaints. The complaints had been tendered to help demonstrate some basis in fact for an alleged defect. In its decision, the court emphasized the limited utility of online complaints to demonstrate some basis in fact, and the narrow scope of documentary evidence that may be submitted through a lawyer's affidavit.

Evidence submitted for "some basis in fact"

In Carter, the plaintiffs alleged that some of the defendants' vehicles contained a defective water pump system and that the defendants were aware of the defect. In support of its motion for certification, and to demonstrate some basis in fact that the defendants were aware of the defect, the plaintiffs submitted a lawyer's affidavit that attached as exhibits anonymous complaints from the website of the U.S. National Highway Traffic Safety Administration (NHTSA).

As noted by the defendants, the evidence of NHTSA complaints raised a number of concerns including that:

1. the individuals who made the complaints were not identified;
2. the complaints were not verified or corroborated;
3. the statements were more prejudicial than probative; and
4. many postings were argumentative, inflammatory, and/or expressions of opinion.

Evidentiary burden for certification motions and limited value of online complaints

While recognizing that the standard of proof required on a motion for certification is unique (i.e. low), the court emphasized that the normal rules with respect to admissibility, including hearsay evidence, still apply. While a plaintiff need only demonstrate "some basis in fact" for the proposed common issues, the evidence submitted to meet that threshold must be admissible. Further, the court reiterated that documentary evidence may only be admissible through a lawyer's affidavit if the evidence is probative of a material fact in issue and the probative value outweighs any prejudice caused by admitting the evidence.

This decision follows earlier decisions addressing the limited value of online complaints, such as Thorpe v. Honda Canada Inc.² (Thorpe), Williams v. Canon Canada Inc.³, and Beazley v. Suzuki Motor Corp⁴. In each of these cases, the courts determined that anonymous online complaints were of limited (or no) probative value on a motion for certification and were inadmissible.
