A Quebec court has ruled that Six Flags Montreal, formerly known as La Ronde, violated the province's anti-scab provisions during a labour dispute in 2023. The decision, issued on May 19, 2026, found that the amusement park used replacement workers during a strike by unionized employees, contravening Quebec's Labour Code.
Court Findings
The court determined that Six Flags Montreal employed non-union workers to perform duties typically carried out by striking employees, which is prohibited under Quebec's anti-scab legislation. The law aims to prevent employers from undermining strikes by hiring replacement workers. The judge noted that the park's actions undermined the collective bargaining process and the rights of workers.
Compensation and Penalties
As a result of the ruling, Six Flags Montreal has been ordered to compensate the affected workers for lost wages and benefits. Additionally, the park faces financial penalties for each violation. The exact amount of compensation and fines will be determined in a subsequent hearing. The union representing the workers hailed the decision as a victory for labour rights.
Background of the Dispute
The labour conflict began in May 2023 when approximately 500 unionized employees at La Ronde went on strike over wages and working conditions. The strike lasted several weeks, during which the park remained open using temporary workers. The union filed a complaint with the Quebec Labour Board, alleging that the park was violating anti-scab provisions. The board investigated and referred the matter to court.
Impact on Operations
The ruling may affect Six Flags Montreal's operations during future labour disputes, as the park must now comply strictly with anti-scab laws. The company has indicated it will review the decision and consider its options, including a possible appeal. Meanwhile, the union has expressed hope that the decision will lead to improved labour relations at the park.
Broader Implications
Labour experts say the ruling reinforces Quebec's strong anti-scab protections, which are among the most stringent in North America. The decision could set a precedent for other employers in the province who might consider using replacement workers during strikes. It also highlights the importance of adhering to labour laws designed to balance the power between employers and employees.
Reactions
Union leaders praised the court's decision, calling it a win for all workers in Quebec. They urged Six Flags Montreal to respect the ruling and engage in good-faith negotiations. The company has not yet commented on whether it will comply with the order or seek an appeal. The case continues to draw attention from labour rights advocates across Canada.
