TORONTO -- The regulatory body for Ontario's medical profession has barred two outspoken doctors from issuing any medical exemptions related to COVID-19 vaccinations.

The College of Physicians and Surgeons of Ontario announced the restrictions against Dr. Mark Trozzi, of Harrow, and Dr. Rochagne Kilian, of Owen Sound, on Monday morning.

Both Trozzi and Kilian have been outspoken about COVID-19 restrictions in the past while expressing skepticism about COVID-19 vaccines.

Kilian, in particular, has previously been a speaker at several rallies organized by the group “Grey-Bruce Freedom Fighters” and last month resigned from her position as an emergency room doctor in protest over the Grey Bruce Health Services handling of the pandemic.

Under the interim order announced today but issued last week, the physicians have been barred from providing medical exemptions in relation to COVID-19 vaccines, mandatory mask requirements for COVID-19 and testing for COVID-19.

Their practices will also be required to post information about restrictions in their offices.

The college said that it is issuing the interim orders under powers granted to it in 2018, which permits it to “suspend or impose terms, conditions or limitations on a member’s certificate of registration where the college believes that the conduct exposes or is likely to expose patients to harm or injury.

Neither doctor has been referred to the tribunal with allegations related to the restrictions at this point.

Chief Medical Officer of Health Dr. Kieran Moore has previously said that COVID-19 vaccines are safe and highly effective and that medical exemptions should only be granted at a rate of about five people per 100,000.

He has said that the only two legitimate medical exemptions are an allergy to one of the components of the vaccine or an increased risk of myocarditis.
