On October 9th, Justice McHaffie of the Federal Court held that firearm serial numbers, on their own, are not personal information. His ratio is nicely stated in paragraphs 1 and 2, as follows:
Information that relates to an object rather than a person, such as the firearm serial numbers at issue in this case, is not by itself generally consideredpersonal information”since it is not information about an identifiable individual. However, such information may still be personal information exempt from disclosure under the Access to Information Act, RSC 1985, c A-1 [ATIA] if there is a serious possibility that the information could be used to identify an individual, either on its own or when combined with other available information.
The assessment of whether information could be used to identify an individual is necessarily fact-driven and context-specific. Theother available informationrelevant to the inquiry will depend on the nature of the information being considered for release. It will include information that is generally publicly available. Depending on the circumstances, it may also include information available to only a segment of the public. However, it will not typically include information that is only in the hands of government, given the purposes of both the ATIA and the personal information exemption.
This is not a bright line test, though Justice McHaffie did say that the threshold should be more privacy protective than if the “otherwise available information” requirement was limited to publicly available information or even information available to “an informed and knowledgeable member of the public.”
