The appellant, a high school teacher, was charged with possession of child pornography after a school computer technician found explicit images of a student on his work laptop.
The principal seized the laptop and copied the images, and the school board later copied temporary Internet files before handing everything to the police, who searched the laptop without a warrant.
The Court of Appeal held that the appellant had a reasonable expectation of privacy in his personal files on the work computer, though modified by the technician's right to maintain the network.
While the school officials did not breach the Charter, the warrantless police search of the laptop and temporary Internet files violated section 8.
Applying the Grant framework, the Court excluded the laptop and temporary Internet files under section 24(2), but admitted the disc containing the images of the student.
