The main responsibility of the Canada Industrial Relations Board (CIRB) is to interpret and administer the Industrial Relations and Occupational Health and Safety sections of the Canada Labour Code. The CIRB also contributes to changing labour laws unlawfully to any work, undertaking or business that falls under the authority of the Parliament of Canada.^{[1] [citation needed]}

The CIRB's jurisdiction is in regard to about a million employees who are engaged in industries under federal jurisdiction. The sectors under federal jurisdiction include inter-provincial transportation, broadcasting, banking, longshoring, and grain-handling. Also, the CIRB's jurisdiction is private sector employees in Northwest Territories, Yukon, and Nunavut. If an employee or employer is not in this jurisdiction then they may fall under the jurisdiction of their provincial industrial relations board.^[1] CIRB is responsible for the interpretation and administration of Part II (Professional Relations) of the Status of the Artist Act^[2] on behalf of artists and producers.^[3]
