Canada Labour Code — L-2 87.4
Maintenance of activities 87.4 (1) During a strike or lockout not prohibited by this Part, the employer, the trade union and the employees in the bargaining unit must continue the supply of services, operation of facilities or production of goods to the extent necessary to prevent an immediate and serious danger to the safety or health of the public. Agreement (2) An employer and a trade union must, no later than 15 days after the day on which notice to bargain collectively has been given, enter into an agreement with respect to compliance with subsection (1) that sets out (a) the supply of services, operation of facilities or production of goods that they consider necessary to continue in the event of a strike or a lockout; and (b) the manner and extent to which the employer, the trade union and the employees in the bargaining unit must continue that supply, operation and production, including the approximate number of those employees that, in the opinion of the employer and the trade union, would be required for that purpose. For greater certainty (2.1) For greater certainty, if the employer and the trade union conclude that it is not necessary to continue any supply of services, operation of facilities or production of goods in order to comply with subsection (1), they must set out this conclusion in the agreement referred to in subsection (2). Filing with Minister and Board (3) Immediately after entering into the agreement, the employer and the trade union must file a copy of it with the Minister and the Board. When the agreement is filed, it has the same effect as an order of the Board. If no agreement entered into (4) If the employer and the trade union do not enter into an agreement within the period referred to in subsection (2), the Board must, on application made by either of them, determine any question with respect to the application of subsection (1). Referral (5) The Minister may refer to the Board any question with respect to whether an agreement entered into by the employer and the trade union is sufficient to ensure that subsection (1) is complied with. Board order (6) If, in determining an application made under subsection (4) or referral made under subsection (5), the Board is of the opinion that a strike or lockout could pose an immediate and serious danger to the safety or health of the public, the Board, may, by order (a) designate the supply of those services, the operation of those facilities and the production of those goods that it considers necessary to continue in order to prevent an immediate and serious danger to the safety or health of the public; (b) specify the manner and extent to which the employer, the trade union and the employees in the bargaining unit must continue that supply, operation and production; and (c) impose any measure that it considers appropriate for carrying out the requirements of this section. Time limit (6.1) Despite subsection 14.2(2), the Board must determine an application made under subsection (4) or a referral made under subsection (5), make any order under subsection (6) and send a copy of its decision and any order to the parties no later than 82 days after the day on which it received the application or referral. Late order or decision not invalid (6.2) The failure of the Board to comply with the time limit does not affect the jurisdiction of the Board to continue with and determine the application or referral and any order or decision made by the Board after the time limit is not for that reason invalid. For greater certainty (6.3) For greater certainty, the Board may exercise any of its powers under this Part, including any powers respecting its processes and procedures, for the purpose of ensuring, to the extent possible, that it complies with the time limit referred to in subsection (6.1). Filing of agreement before decision (6.4) An employer and trade union may enter into an agreement referred to in subsection (2) and file it in accordance with subsection (3)
