How do I request my own chart under PHIPA or my province's privacy law?

Start with the clinic, hospital, or other health information custodian that holds the chart, and ask for their access-to-records process. In Ontario, PHIPA is the statute that generally governs personal health information, and the Information and Privacy Commissioner of Ontario explains health privacy rights, including access. Other provinces have their own health privacy statutes; they are not all called PHIPA, so using Ontario wording in another province can send you to the wrong office.
