Mandatory Reporting

Mandatory reporting legally requires a dentist to provide information about themselves, another dentist or another regulated health professional to the RCDSO, other relevant regulators or authorities. It is in the interest of public safety that this critical information is brought forward as soon as possible. Dentists must comply with their legal, professional and ethical reporting obligations.

The Regulated Health Professions Act, 1991 (RHPA) sets out a fine of up to $50,000 for an individual and $200,000 for a corporation for failure to make certain types of mandatory reports.
