Doctor Simon Locke was a Canadian medical drama The series was initially a medical drama that originated from the fictional rural town of Dixon Mills, where a young physician, Dr. Simon Locke, arrived in town to assist veteran physician Dr. Andrew Sellers. The plot lines were more fitting for a big city medical drama, including a typhoid epidemic, child abuse, and even a murder.

In 1972 the series was renamed as Police Surgeon, where Dr. Locke moved back to the city and worked for the police department's emergency unit, where he assists the cops in solving crimes that require medical research.
