In the case of R.v.Tessling, the Supreme Court of Canada held that no warrant could ever be granted on the basis of heat emissions (FLIR) alone. The court ruled that the use of FLIR technology to detect heat emissions from a private residence without a warrant violated the reasonable expectation of privacy and constituted an unreasonable search and seizure under s. 8 of the Canadian Charter of Rights and Freedoms. This decision set an important precedent for the use of surveillance technologies by law enforcement agencies in Canada.
