B.C. Court Rules Forward Looking Infra-Red Technology Does Not Constitute a Search

Ruling on a voir dire (hearing on the admissibility of evidence), Higinbotham J. of the Provincial Court of British Columbia recently held in the case of R. v. Rugg that the use of Forward Looking Infra-Red ("FLIR") technology to determine the heat signature of a private home did not constitute a search within the meaning of Section 8 of the Charter of Rights and Freedoms (the "Charter"). In Rugg, the police had searched the home of the accused and discovered a marijuana cultivation operation pursuant to a warrant obtained in part through the use of an FLIR device. When used to scan the home of the accused, the FLIR device had yielded a heat signature consistent with such a marijuana cultivation operation.

In reaching the conclusion that the use of the FLIR device was not a search within Section 8 of the Charter, Higinbotham J. stated that residents do not have a reasonable expectation of privacy as to the amount of heat emanating from their homes.

It is important to contrast the decision of Higinbotham J. with an earlier decision of the Ontario Court of Appeal in R. v. Tessling, where it was held that the use of an FLIR device does constitute a search within the meaning of Section 8 of the Charter. In that case, Abella J.A. noted that FLIR technology indirectly reveals information about activities that are carried on inside the home and discloses more information than is detectable by normal observation or surveillance.
