CanadaCan my roommate or partner consent to police searching our shared computer?
No — in Canada, your roommate or partner cannot legally consent to a police search of your private data on a shared computer, even if they have physical access to the device.
What the Law Says
The Canadian Charter of Rights and Freedoms protects individuals from unreasonable search and seizure. While no specific statute addresses roommate consent for digital devices, Section 8 of the Charter sets the constitutional standard.
Section 8 of the Charter states that 'Everyone has the right to be secure against unreasonable search or seizure.' This right applies to digital information, including files stored on computers — even those shared with others.
The law does not allow one person to waive another’s Charter-protected privacy interest simply by virtue of sharing a device. Consent to search must be both valid (freely given, informed, and within authority) and limited to areas where the consenting person has 'joint control' — but joint physical access does not equal joint privacy interest in personal data.
Courts assess whether a person had a 'reasonable expectation of privacy' in the information searched — a fact-specific inquiry focusing on ownership, control, subject matter, and the circumstances of use.

What Courts Have Said
The Supreme Court of Canada directly addressed this issue in R. v. Reeves, establishing critical limits on third-party consent for shared digital devices.
The Court held that a person retains a reasonable expectation of privacy in their personal data on a shared computer, and that consent by a co-user does not automatically authorize police to search that data — especially where the co-user had no authority over the other’s files and the police knew or ought to have known about the privacy interests involved.
What to Do
Do not assume your roommate’s consent covers your files — it generally does not.
If police ask to search a shared computer, clearly state that you do not consent to any search of your personal data or accounts.
Ask whether they have a warrant — without one, and without your valid consent, the search is likely unlawful.
If data is seized, consult a lawyer promptly; evidence obtained in violation of Section 8 may be excluded under section 24(2) of the Charter.
