This is Part II of a two-part article that provides a broad overview and comparative study of the new Ontario health sector-specific privacy legislation. In Part I, which appeared in the previous issue of Healthcare Quarterly, we discussed the objectives, structure and scope of, as well as the substantive rights and obligations created by, the new Ontario Act. In Part II, we discuss the administrative obligations created by the Ontario Act, as well as the provisions relating to the enforcement of, and remedies available under, the Act. We also contrast the Ontario Act with the various approaches to the protection of personal health information that has already been adopted by other provinces, including Alberta, Saskatchewan and Manitoba.
