Canada’s New Labour Bill Sparks Union Backlash
The Liberal government’s Bill C‑39, introduced on September 21, 2026, has ignited a fierce debate between federal officials and labour unions.

On Monday, September 21, 2026, the Liberal government tabled Bill C‑39, a sweeping economic reform package that includes a controversial amendment to the Canada Labour Code. The new language would allow a federal minister to invoke Section 107 and end a strike or lockout if the action is deemed contrary to the national interest. Labour leaders across Canada have condemned the bill as a direct attack on the right to strike, while government officials insist it merely introduces safeguards for critical industries.
What the Bill Says About Strike Power
Under the current Canada Labour Code, Section 107 can be used by the federal labour minister to refer a deadlocked dispute to the Canada Industrial Relations Board, which may declare an impasse and move the parties into binding arbitration. Bill C‑39 would expand that provision, making it possible for a minister to unilaterally terminate a strike if it is judged to threaten the national interest. The bill specifies that the strike must be affecting the national interest before the minister can trigger the clause, a requirement that critics argue is vague and open to broad interpretation.
Jobs Minister Patty Hajdu defended the amendment, saying it would “help improve labour relations and reduce the number of times negotiations hit a boiling point.” She added that the new rule would only be used in emergencies, and that the government would evaluate each strike on a case‑by‑case basis. “It is a high bar to establish a national interest,” Hajdu said. “Each strike in each industry is different, so it is hard to give a blanket answer.”
Union Reaction and Legal Concerns
Bea Bruske, president of the Canadian Labour Congress (CLC), called the bill a “red flag” for the labour community. She said the government’s promise to protect the right to strike was contradicted by the new language, which she described as giving the minister “complete and unlimited discretion” to decide who can strike and who cannot. The CLC has already begun discussions with legal advisers about possible court challenges, although the union says those conversations are in early stages.
Lawyer Mark Rowlinson of Goldblatt Partners LLP echoed the union’s concerns, arguing that the amendment would formalize a power that was never intended when Section 107 was first introduced in 1984. Rowlinson warned that removing workers’ leverage in collective bargaining could undermine the balance between employers and employees.
Past Use of Section 107 and Current Controversy
In recent years, the federal government has used Section 107 to intervene in high‑profile disputes, including walkouts at Canada Post, the CN and CPKC railways, and the ports of British Columbia and Montreal. In 2025, Air Canada flight attendants resisted an attempt to use the measure to end their strike, leading to court challenges that argue the government overstepped its authority. These cases have set a precedent that the new bill could intensify, raising questions about the limits of ministerial power.
While the government claims the bill would only be invoked in emergencies, critics argue that the lack of clear criteria could lead to arbitrary use. The CLC has highlighted that the proposed changes could nullify workers’ right to withhold labour, a core component of collective bargaining leverage.
Other Provisions and Potential Benefits
Bill C‑39 also introduces a special mediator to publish reports outlining both sides’ positions in an impasse, and requires pre‑emptive relationship repair work with the federal mediation service when there is a history of acrimony between a union and an employer. Bruske welcomed these features, noting that they could support many aspects of the legislation, such as additional resources for the Canada Industrial Relations Board, workplace safety inspections, and measures to crack down on wage theft and contract flipping.
Jobs Minister Hajdu said the bill aims to reduce the number of work stoppages by boosting transparency and cutting “bad blood” between parties. She emphasized that strikes could still happen under the new legislation and that the government would evaluate each situation individually.
What Happens Next?
The CLC is preparing legal strategies to challenge the bill, while the government has stated it will continue to monitor the legislation’s impact on national interest and labour relations. The debate is expected to intensify as Parliament debates the bill over the coming weeks, with unions calling for a complete repeal of the Section 107 amendment. The outcome will shape the future of collective bargaining and strike rights in Canada.
As the discussion unfolds, stakeholders on both sides will be closely watching how the bill’s provisions are interpreted and applied in real‑world disputes, and whether the promised safeguards truly protect the national interest without eroding workers’ fundamental rights.
