Workers at several hospitals accessed the health records of former Toronto mayor Rob Ford.
"It is often the high-profile cases and individuals by the nature of the breach that may get more attention," said Hoskins. "I don't want to speak to the specifics that are being investigated and may be prosecuted."
Hoskins said the new legislation will double fines for violations of patients' privacy to $100,000 for individuals and $500,000 for the hospital or organization. It would also scrap a rule requiring that prosecutions start within six months of the alleged privacy breach, which Hoskins called "a serious barrier" to prosecuting offenders.
"That has made it extremely difficult to conduct an investigation and has made prosecutions very rare," he said.
Only three cases of breaching private medical records have ever been referred for prosecution, and there has never been a successful prosecution under the Personal Health Information Protection Act since it was introduced in 2004. One case was unsuccessful and the two others are still under consideration by the Attorney General's office.
