If you work for CN Rail, Air Canada, Bell Canada, or one of Canada's major port operators, the federal framework governing your next collective agreement dispute is being actively rewritten. In July 2026, Employment and Social Development Canada (ESDC) launched a targeted second round of consultations on the Canada Labour Code, Part I (Industrial Relations), focused on two mechanisms that defined some of the most disruptive work stoppages of 2024 and 2025: the replacement-worker prohibition introduced under Bill C-58, and the ministerial power to impose binding arbitration under Canada Labour Code s. 107.

Federal Labour Minister Patty Hajdu has signalled that Ottawa will examine guardrails and alternatives to what she characterised as a contentious Labour Code tool. For anyone sitting at a federal bargaining table in the next two years, that framing is precise: the levers that determine how long a dispute runs, who bears the financial cost of a work stoppage, and whether a cabinet minister can cut one short are all under review before the next contract cycles open.

What Ottawa actually reopened

ESDC published the second-phase consultation document under the initiative titled Building Canada Strong for All, Powered by Canada's Workers. Canadian HR Reporter characterised the process as one designed to go deeper on important issues and validate earlier feedback collected in Phase 1. That framing matters: this is not a blank-sheet review. Ottawa has already received one round of submissions and is now pressure-testing specific proposals that emerged from those earlier sessions.

Two mechanisms sit at the centre of the review:

• Replacement workers under Bill C-58. The federal ban on using replacement workers during a strike or lockout in federally regulated industries came into force on November 1, 2024, under amendments introduced by Bill C-58 (An Act to amend the Canada Labour Code). The second-round document invites feedback on how that ban has functioned in practice, including how essential-services carve-outs have been defined and whether the prohibition has changed bargaining dynamics as anticipated.
• Ministerial intervention under s. 107. Canada Labour Code s. 107 gives the Minister of Labour the authority to refer a dispute to the Canada Industrial Relations Board (CIRB) for binding arbitration or to impose other resolution mechanisms. Hajdu has confirmed the government is examining whether the bar for triggering that power should be formalised, a change with significant implications for how long any federally regulated dispute runs before external resolution is imposed.

Why the mechanics matter more than the labels

The Canada Labour Code, Part I, covers federally regulated industries: banking, telecommunications, interprovincial rail and trucking, ports, and aviation. That translates to roughly 6 to 8 percent of Canada's unionised workforce, a share that looks modest until you consider which employers it includes: CN Rail, Canadian Pacific Kansas City (CPKC), Air Canada, Bell Canada, Rogers Communications, Telus, and the major chartered banks. When any of those workforces stop, supply chains stop. That concentration of economic leverage is precisely why ministerial intervention became the headline resolution tool in several of Canada's 2024 and 2025 disputes, and precisely why adjusting the threshold for invoking it reshapes the psychology of every future negotiation.

A union that expects an early s. 107 referral has less incentive to make concessions in the opening weeks of a stoppage. An employer that expects the Bill C-58 replacement-worker ban to hold firm cannot model a partial-operations contingency. Both sides calibrate their positions based on what the framework allows. The second-round consultation reopens exactly that calibration question.

For employees

If your workplace falls under the federal Labour Code, this consultation window is the point at which the rules governing your next dispute are being set. Here are the most concrete things to consider:

• Check your bargaining calendar. If your collective agreement expires in 2027 or 2028, the framework that governs that round is being shaped now. Rule changes tend to precede contract cycles, not follow them.
• Know what your union is filing. Ask your local representative what position your union is submitting to the ESDC consultation, specifically on the two central questions: the replacement-worker ban under Bill C-58 and the s. 107 intervention threshold. Unifor, Teamsters Canada, and the Public Service Alliance of Canada (PSAC) all represent workers in federally regulated sectors that have been directly affected by both mechanisms. Members who understand the ask are better placed to support it publicly.
• Respond individually if your local is not active. ESDC's targeted second-phase document accepts individual submissions, not only union filings. Individual workers in federally regulated sectors can put their experience on record, particularly around how the replacement-worker ban has or has not changed conditions during recent disputes.
• Understand the federal-versus-provincial distinction. If you are considering moving between a federally regulated employer and a provincially regulated one, or vice versa, the rules you would bargain under differ materially. Ontario's Employment Standards Act 2000 and the BC Employment Standards Act govern roughly 94 percent of Canadian workers, but they contain their own replacement-worker and dispute-resolution provisions, which are not affected by this federal consultation. The Canada Labour Code changes apply only to the federally regulated slice.

For workers in rail, ports, or aviation who lived through stoppages that ended via ministerial referral in 2024 or 2025, the consultation is also a structured opportunity to put that experience on the record, specifically on whether an early intervention shortened a dispute that might otherwise have produced a more durable settlement.

For HR and employer decision-makers

If you advise a federally regulated employer, or sit inside one, the second-round consultation is the moment to model what your next bargaining cycle looks like under several different framework scenarios, not only the current one. Chartered Professionals in Human Resources (CPHR Canada) and federally regulated employer associations such as the Federal Employers Transportation and Communications Organization (FETCO) are the natural channels for coordinated submissions, but individual employers can also file independently. The variables that carry the most weight:

• Bill C-58 replacement-worker scope. If the ban remains in its current form or is tightened further, business-continuity planning during a work stoppage is constrained to managerial staff and any pre-agreed essential-services carve-outs negotiated under Canada Labour Code s. 87.4. Continuity modelling should be built against that constraint explicitly, not against the pre-November 2024 baseline when replacement workers were available.
• S. 107 intervention threshold. If Ottawa sets a formal or higher bar for ministerial referral, disputes in transportation, telecom, and ports will run longer before external resolution is available. Financial-impact modelling and contingency stockpiles should reflect a materially longer stoppage duration than was typical when s. 107 referrals arrived within two to three weeks of a work stoppage beginning.
• Submission strategy. Phase 2 is a direct channel to shape Phase 3 outcomes. Employers that file substantive, evidence-based submissions, either individually or through sector associations, have a documented presence in the public record that carries weight when legislative amendments are drafted. Employers that sit out the consultation have limited standing to object to the framework that results.

For HR teams in the affected sectors, the workforce-planning implications extend well beyond the bargaining table. Retention and recruitment tend to tighten in the period leading into a high-profile federal dispute, and the framework ESDC settles on will influence how publicly visible each conflict becomes. The employer that plans for a longer stoppage and communicates clearly with non-union staff about operational continuity typically sustains less lasting damage to its employer brand than one that assumes a ministerial referral will arrive on day ten.

What to watch next

ESDC has committed to publishing feedback and next steps as part of the Powered by Canada's Workers initiative. Three signals are worth tracking closely:

• Whether the Bill C-58 replacement-worker prohibition is tightened, loosened, or clarified around essential-services definitions under Canada Labour Code s. 87.4, particularly following the disputes at major ports and rail carriers in 2024.
• Whether Minister Hajdu proposes a formal procedural threshold before s. 107 can be invoked, a reform that would slow political pressure to end a stoppage quickly and shift the cost-benefit calculation at the bargaining table for both sides.
• Which sectoral employers and unions file substantive, publicly available submissions. FETCO filings and submissions from Unifor, Teamsters Canada, and the Canadian Labour Congress (CLC) will be the earliest visible signal of where the framework is heading before any legislative amendment is tabled.

The Canada Labour Code is not being rebuilt from the foundation. It is being adjusted, and the adjustments are being made now, in a consultation window that most workers and a significant number of HR teams will not track because it lacks the visibility of an active work stoppage. That is precisely the dynamic that allows leverage-shaping decisions to be made in consultation processes rather than at picket lines, and precisely why filing a position, or at minimum reading what others file, is a concrete step worth taking before the window closes.
