  • The STM fully recognizes the importance of privacy and is committed to taking the necessary measures to properly safeguard the confidentiality of all personal information entrusted to it. As such, it is also committed to being transparent and complying with all applicable regulations concerning access to and the protection of personal information.
  • To allow people to access and use certain services, or to comply with its legal obligations, the STM must collect, use and retain certain personal information and/or share it with its authorized partners.
  • Personal information is information about a natural person that directly or indirectly allows that person to be identified.
  • The STM invites all those concerned to familiarize themselves with this policy, as it presents the information on which they should base the decision to consent to the collection, use and sharing of their personal information by the STM and its authorized partners.

Why have we adopted this policy and who does it apply to?

  • This policy applies to anyone the STM collects personal information from or about in the course of its operations.
  • The policy defines how the STM protects the personal information entrusted to it and specifies the rules and procedures for the collection, use, sharing, retention and correction of said information, as well as the right of access to it. It covers all personal information that is collected, particularly via forms and technological means by which services are offered to users (e.g., the STM’s websites and applications).
