Canada Implements Ban on Replacement Workers in Federal Sector
Last Updated: Jul 8, 2025
On June 20, 2025, a new Canadian law, Bill C-58, came into force, prohibiting the use of replacement workers during strikes or lockouts in all federally regulated workplaces. This significant amendment to the Canada Labour Code prevents employers in sectors like airlines, railways, and telecommunications from using contractors, temporary staff, or managers hired after a notice to bargain was given to perform the duties of striking or locked-out union members.
The law also effectively bars bargaining unit employees from crossing a picket line during a full work stoppage. Limited exceptions are permitted, such as for contractors who were already performing the same work before the labor dispute began, or in situations that pose an imminent and serious threat to public health and safety or to the employer's property. The legislation, which carries fines of up to $100,000 per day for violations, is intended to protect workers' right to strike and encourage good-faith bargaining.
