College of Physicians and Surgeons of Ontario

The College of Physicians and Surgeons of Ontario (CPSO) is the regulatory college for medical doctors in Ontario, Canada.

The college issues certificates of registration for all doctors to allow them to practise medicine as well as: monitors and maintains standards of practice via assessment and remediation, investigates complaints against doctors, and disciplines those found guilty of professional misconduct and/or incompetence.

The CPSO's power is derived from Regulated Health Professions Act (RHPA), Health Professions Procedural Code under RHPA and the Medicine Act. The college is based in Toronto.

In October 2008, the college was named one of "Canada's Top 100 Employers" by Mediacorp Canada Inc., and was featured in Maclean's newsmagazine. Later that month, the college was also named one of Greater Toronto's Top Employers, which was announced by the Toronto Star newspaper.
