CanadaCan a company share my personal information with third parties without telling me?
No, a company cannot share your personal information with third parties without your valid, informed consent under Canadian federal privacy law.
What the Law Says
Canada’s main federal privacy law for the private sector — the Personal Information Protection and Electronic Documents Act (PIPEDA) — sets strict rules about when and how organizations can share your personal information with third parties.
Organizations must follow the 10 privacy principles in Schedule 1 of PIPEDA — known as the CSA Model Code for the Protection of Personal Information. These include accountability, identifying purposes, consent, limiting collection, and disclosure restrictions.
Consent is central: under section 6.1, consent is only valid if it is reasonable to expect that you understand the nature, purpose, and consequences of the disclosure. This means vague or buried language in a long privacy policy is not enough — the organization must make the sharing clear and meaningful.
Section 5 reinforces this by requiring organizations to comply fully with all obligations in Schedule 1. That includes Principle 4.3 (‘Consent’), which states that ‘the knowledge and consent of the individual are required for the collection, use, or disclosure of personal information, except where inappropriate.’ Sharing with third parties almost always requires express consent.

What to Do
Read the organization’s privacy policy carefully — look for specific language about sharing with third parties (e.g., ‘we may share your information with marketing partners’).
Withhold consent if the purpose or consequences aren’t clearly explained — you have the right to say no.
Contact the organization’s privacy officer to ask how your information will be used or shared.
File a complaint with the Office of the Privacy Commissioner of Canada (OPC) if you believe your consent wasn’t properly obtained.
