Claims involving unidentified motorists present a unique evidentiary challenge. Where the at-fault driver cannot be identified, an insured seeking indemnification under the Ontario Policy Change Form 44R (OPCF 44R) must satisfy an additional statutory requirement before coverage may be available.
Section 1.5(D) of the OPCF 44R requires the insured to provide corroborating evidence of the involvement of an unidentified motorist. While the wording of the provision appears relatively straightforward, Ontario courts have interpreted it broadly, providing useful guidance on the nature and quality of evidence that may satisfy the requirement.
The Corroboration Requirement
Section 1.5(D) of the OPCF 44R provides that an insured or eligible claimant must corroborate the existence of an at-fault unidentified motorist through “other material evidence.” The corroborating evidence must consist of either:
The provision recognizes the inherent difficulty in proving claims involving unidentified drivers while seeking to ensure that such claims are supported by objective evidence.
How Have the Courts Interpreted “Physical Evidence”?
The leading decisions interpreting section 1.5(D) demonstrate that the concept of “physical evidence” is not limited to evidence found at the accident scene.
Azzopardi v. John Doe
In Azzopardi v. John Doe, the plaintiff alleged that he lost control of his motorcycle after an unidentified vehicle cut him off. There was no contact between the vehicles, police did not attend the scene, and two individuals who reportedly witnessed the incident were never identified.
The Court rejected the argument that physical evidence under section 1.5(D) is confined to skid marks, debris, or vehicle damage. Instead, it held that medical documentation confirming injuries consistent with the plaintiff’s account could constitute “physical evidence indicating the involvement of an unidentified vehicle.”
In reaching this conclusion, the Court emphasized the remedial purpose of the OPCF 44R and noted that a restrictive interpretation would unnecessarily limit the availability of coverage in circumstances where no physical contact occurred.
Mazinani v. John Doe
The Court adopted a similarly broad approach in Mazinani v. John Doe. The plaintiff alleged that an unidentified vehicle failed to stop at a stop sign, causing a motorcycle collision.
The available corroborating evidence consisted primarily of the investigating officer’s notes and photographs showing damage to the motorcycle. The Court concluded that this evidence was sufficient to satisfy section 1.5(D).
Significantly, the Court observed that the provision requires evidence that indicates the involvement of an unidentified vehicle, rather than evidence that conclusively proves it. As with many forms of circumstantial evidence, corroborating evidence may support more than one possible inference without losing its evidentiary value.
A Fact-Specific Assessment
The decisions in Azzopardi and Mazinani illustrate that Ontario courts have adopted a flexible approach to the corroboration requirement. Depending on the circumstances, police documentation, medical records, photographs, vehicle damage, and other objective evidence may all be capable of satisfying section 1.5(D).
Whether the statutory requirement has been met, however, remains a fact-specific inquiry. The existence, quality, and weight of the corroborating evidence must be assessed in the context of the record as a whole.
Key Takeaways
Section 1.5(D) of the OPCF 44R requires objective corroborating evidence to support claims involving unidentified motorists. Ontario courts have interpreted this requirement broadly, recognizing that the evidence need only indicate—not conclusively establish—the involvement of another vehicle.
The case law also demonstrates that corroborating evidence is not confined to traditional accident scene evidence. Medical records, police documentation, photographs, and other objective evidence may satisfy the statutory requirement, provided they are capable of supporting the inference that an unidentified motor vehicle was involved.
Ultimately, whether section 1.5(D) has been satisfied will depend on the particular facts and evidence available in each case.
