No person may use or attempt to use information that has been de-identified to identify an individual, either alone or with other information, unless the Act or another Act permits the information to be used to identify the individual, subject to any prescribed exceptions.

The limit does not prevent a health information custodian, a prescribed entity mentioned in subsection 45 (1), a prescribed person who compiles or maintains a registry of personal health information, or any other prescribed person from using information that they de-identified to identify an individual.

To de-identify personal health information means to remove any information that identifies the individual or for which it is reasonably foreseeable in the circumstances that it could be utilized, either alone or with other information, to identify the individual.
