This document discusses the legal requirements for recognizing and preventing occupational diseases in Canada. It outlines that there are 14 occupational health and safety jurisdictions in Canada, including one federal jurisdiction, three territorial, and ten provincial. The federal jurisdiction is governed by the Canada Labour Code Part II and associated regulations. These regulations require employers to investigate workplace hazards, set occupational exposure limits, implement control measures, conduct medical examinations and report occupational diseases and hazardous incidents. The goal is to eliminate hazards, reduce hazards, and provide personal protective equipment to protect workers' health and safety.
