Canada's New Strike Laws Just Changed Everything: 10 Protection Strategies Every Business Owner Needs by June 2025

The landscape of Canadian labor relations shifted dramatically on June 20, 2025, when Bill C-58's anti-scab provisions came into full effect. This federal legislation fundamentally transformed how federally regulated employers can respond to strikes and lockouts, eliminating their ability to use replacement workers during labor disputes.

For business owners in federally regulated sectors: including banking, telecommunications, transportation, and airlines: these changes represent the most significant shift in labor law in decades. The stakes are high: violations can result in fines of up to $100,000 per day, making compliance not just legally necessary but financially critical.

What Bill C-58 Actually Means for Your Business

The new legislation places strict prohibitions on using replacement workers during legal work stoppages. This isn't limited to obvious scenarios like hiring temporary staff: the law encompasses employees hired after notice to bargain, contractors, volunteers, and even existing employees working outside their normal locations.

The prohibition is comprehensive. Employers can only use employees who were hired before any notice to bargain was given, and only if those employees normally worked at the specific location where the strike or lockout is occurring. This creates a narrow window of eligible personnel during labor disputes.

Ten Essential Protection Strategies for Business Continuity

1. Conduct Immediate Workforce Documentation Audits

Your first line of defense requires knowing exactly who can work where and when. Create detailed records mapping every employee's hire date relative to any notice to bargain scenarios. Document normal work locations for each employee, including those with flexible or multi-location arrangements.

This audit should include:

• Employee hire dates and their relationship to bargaining timelines

• Normal work location assignments

• Management personnel classifications

• Contractor and third-party service provider relationships

2. Redesign Strike Contingency Plans Around Core Operations

Traditional strike plans that relied on replacement workers are now obsolete. Focus your contingency planning on identifying which operations are truly essential and which can be temporarily suspended or reduced.

Consider these operational adjustments:

• Advance production and inventory stockpiling

• Automation of critical processes where possible

• Service reduction protocols that maintain safety and legal compliance

• Customer communication strategies for service disruptions

3. Establish Proactive Essential Services Agreements

The new maintenance of activities procedures require proactive engagement with the Canada Industrial Relations Board (CIRB) for collective bargaining processes where notice to bargain was issued after June 20, 2025. Rather than waiting for imposed requirements, negotiate maintenance of activities agreements directly with unions.

These agreements should clearly define:

• Which services qualify as essential

• Minimum staffing requirements for essential operations

• Procedures for maintaining safety and security

• Communication protocols during disputes

4. Implement Comprehensive Management Training Programs

With daily penalties reaching $100,000, even inadvertent violations can devastate your business financially. All management levels need thorough training on identifying struck work, understanding hiring date restrictions, and recognizing prohibited transfers.

Key training components should cover:

• Legal definitions of replacement workers under Bill C-58

• How to identify and avoid struck work assignments

• Documentation requirements for compliance

• Emergency response protocols during labor disputes

5. Strengthen Labor-Management Relationships Now

The power dynamic in collective bargaining has shifted significantly. With employers unable to maintain full operations during strikes, building stronger relationships with union representatives becomes strategically essential.

Invest in:

• Interest-based bargaining training for negotiation teams

• Regular labor-management committee meetings

• Early engagement strategies for contract negotiations

• Conflict resolution mechanisms outside formal grievance procedures

6. Revise All Hiring and Transfer Policies

Management hires made after notice to bargain cannot be used during strikes or lockouts. Establish protocols that automatically flag any pending or active notice to bargain situations before making management appointments or transfers.

Your revised policies should include:

• Pre-hiring bargaining status checks

• Documentation of normal work assignments for all new hires

• Clear protocols for temporary assignments during normal operations

• Regular review of employee work location designations

7. Create Robust Third-Party Service Management Protocols

Contractors and external service providers are subject to the same replacement worker prohibitions. Review all existing service agreements and establish clear protocols for managing third-party relationships during labor disputes.

Essential contract provisions should address:

• Work stoppage clauses that suspend services during strikes

• Clear definitions of struck work that contractors must avoid

• Communication requirements during labor disputes

• Alternative service arrangements for essential functions

8. Develop Real-Time Compliance Monitoring Systems

The law applies immediately to any strike or lockout, including those ongoing when the legislation took effect. You need systems that can halt potentially prohibited activities within hours of a labor dispute beginning.

Effective monitoring systems include:

• 24/7 management contact protocols

• Rapid communication channels for all supervisors

• Clear decision-making hierarchies during emergencies

• Documentation systems for all compliance decisions

9. Prepare for Immediate Financial Impact Assessment

Unlike previous strike scenarios where replacement workers could maintain revenue streams, the new reality requires planning for complete operational shutdowns in affected areas. Develop financial models that account for total work stoppage scenarios.

Financial preparation should include:

• Cash flow projections for extended work stoppages

• Insurance coverage review for business interruption

• Credit facility arrangements for operational continuity

• Customer retention strategies during service disruptions

10. Engage Specialized Legal Counsel for Ongoing Compliance

The complexity of determining struck work, eligible employees, and maintenance of activities requirements demands specialized expertise. The CIRB has developed new forms and procedures, and navigating these processes requires current legal guidance.

Regular legal consultation should cover:

• Quarterly compliance reviews

• Bargaining strategy development

• CIRB application procedures and requirements

• Violation response and mitigation strategies

The Enforcement Reality: $100,000 Daily Penalties

The penalty structure under Bill C-58 represents a clear escalation in enforcement seriousness. At $100,000 per day, violations during extended disputes can accumulate costs that exceed the financial impact of settling the underlying labor dispute.

The Canada Industrial Relations Board oversees enforcement and has established comprehensive procedures for handling complaints and applications under the amended legislation. This includes new forms for both replacement worker complaints and maintenance of activities applications.

Strategic Implications for Business Planning

Labor organizations have characterized this legislation as fundamentally changing the bargaining landscape. The expectation is that by preventing operational continuity through replacement workers, disputes will resolve more quickly: but with greater immediate operational impact.

This shift requires businesses to:

• Invest more heavily in preventing labor disputes

• Develop stronger internal conflict resolution capabilities

• Build operational resilience that doesn't depend on personnel replacement

• Create more collaborative approaches to labor-management relationships
