The Waterloo Regional Health Network (WRHN) says a "security incident" may have exposed the personal health information of thousands of patients. That system is hosted by Ontario Health. WRHN's letter to patients said it can't rule out the possibility that personal health information was compromised. In its statement, WRHN said the investigation shows a "low likelihood that personal health information was accessed or misused." CBC News reached out to Ontario Health for comment, but did not receive a reply by deadline.
