Canada Bolsters Labour Board Amid New Anti-Scab Law Reality

GATINEAU, QC – February 12, 2026 – The Government of Canada has moved to significantly reinforce the ranks of its top federal labour tribunal, announcing a slate of appointments and re-appointments to the Canada Industrial Relations Board (CIRB). The move comes as the board grapples with the ongoing implementation of historic and contentious legislation that bans the use of replacement workers in federally regulated sectors.

In a joint announcement today, Jobs and Families Minister Patty Hajdu and Secretary of State for Labour John Zerucelli named four new full-time Vice-Chairpersons: Lindsay Foley, Dominic Lemieux, Natalie Zawadowsky, and William Hlibchuk. They are joined by two re-appointed members, veteran full-time Vice-Chairperson Louise Fecteau and part-time Vice-Chairperson Lynne Poirier. All six will serve five-year terms.

The appointments are a direct response to the expanded mandate and increased workload facing the CIRB, the independent body responsible for interpreting and administering labour laws for industries like banking, telecommunications, and interprovincial transport. This reinforcement is seen as crucial for navigating the new landscape created by Bill C-58, which came into force in June 2025.

"Strong and effective labour industrial relations are essential to a fair, stable, and productive economy," Minister Hajdu stated in the announcement. "These appointments and reappointments to the Canada Industrial Relations Board will support the Board's important role in resolving workplace disputes and upholding the Canada Labour Code in federally regulated sectors."

A Legislative Sea Change

The backdrop to these appointments is one of the most significant shifts in Canadian labour law in decades. Bill C-58, which officially became law eight months ago, fundamentally altered the dynamics of strikes and lockouts in federally regulated workplaces by introducing a broad prohibition on the use of replacement workers, often referred to as "scabs."

Under the new regime, employers are barred from using nearly all forms of temporary labour to perform the duties of striking or locked-out union members. This includes contractors, managers hired after bargaining began, and employees transferred from other locations. The legislation carries steep penalties for non-compliance, with potential fines reaching $100,000 for each day an offence continues.

Crucially, the law also overhauled the pre-strike process. Unions and employers are now mandated to reach a "maintenance of activities" agreement within 15 days of giving notice to bargain. This agreement outlines which, if any, services must be maintained to prevent immediate threats to public health and safety or serious damage to property. If the parties cannot agree, they must apply to the CIRB, which is tasked with making a binding determination within a tight 82-day timeframe. No strike or lockout can legally occur until such an agreement or CIRB ruling is in place.

This new process has placed the CIRB at the very center of every potential federal labour dispute, making its capacity and expertise more critical than ever.

A Board Under Pressure

Recent statistics from the CIRB itself illustrate the mounting pressure. While the overall number of cases filed in the 2023-24 fiscal year stabilized at 966, the complexity has visibly increased. Matters filed under Part I of the Canada Labour Code, which covers industrial relations and collective bargaining, now constitute nearly half the board's caseload. These are often the most intricate and time-sensitive cases.

This complexity has come at a cost to efficiency. The average processing time for cases climbed to 385 days in the last reported fiscal year, a 26% increase from the year prior. The new responsibilities under Bill C-58 are expected to add further strain, making the addition of five full-time vice-chairpersons a necessary expansion.

"With the appointments made by the Minister today, we are ensuring that the Canada Industrial Relations Board has the capacity and expertise needed to carry out its mandate effectively," said Secretary of State Zerucelli.

The re-appointed members bring a wealth of experience. Louise Fecteau has served on the board since 2003, with a background in both labour and administrative law. Lynne Poirier, a part-time member since 2017, is a seasoned arbitrator, mediator, and former legal counsel for major corporations, bringing a deep understanding of dispute resolution to the tribunal.

A Divided Reaction

The legislative changes that necessitate these appointments have been met with starkly divided reactions from labour and business communities. For decades, unions like Unifor and the Canadian Labour Congress championed the ban on replacement workers, hailing its passage as a "historic victory" that levels the playing field during contract negotiations. They argue it prevents employers from undermining the power of a strike and incentivizes good-faith bargaining to avoid lengthy work stoppages.

Conversely, employer groups such as the Canadian Chamber of Commerce have voiced grave concerns. They warned that the legislation would destabilize labour relations, leading to more frequent and prolonged strikes that could cripple Canada's supply chains and harm the national economy. They contend that removing the option to maintain operations during a dispute removes a key incentive for unions to reach a settlement.

As the arbiters of this new reality, the newly expanded CIRB is now on the front lines. Its members will be responsible for interpreting the nuances of the replacement worker ban, ruling on contentious maintenance of activities disputes, and adjudicating unfair labour practice complaints. Their decisions in the coming months and years will set critical precedents, shaping the future of federal labour relations and determining whether the new law achieves its goal of promoting industrial harmony or triggers the instability its critics predicted.
