Canada Labour Code

Structure and Scope

The Canada Labour Code, RSC 1985, c L-2 (the “Code”), is the comprehensive federal labour statute governing workplace relations, occupational health and safety, and employment standards for federally regulated industries. Enacted in its modern form in 1966 (following the Canada Labour (Standards) Code, SC 1964, c 39), the Code applies to operations within federal jurisdiction under s. 92(10) of the Constitution Act, 1867 — including interprovincial and international transportation (railways, airlines, trucking, shipping), telecommunications, broadcasting, banking, grain handling, uranium mining, and federal Crown corporations. Approximately 6–8% of Canadian workers are subject to the Code, with the remainder governed by provincial employment and labour legislation.

The Code is divided into three distinct Parts, each with its own administrative tribunal and enforcement regime, unified conceptually by the federal government’s constitutional labour jurisdiction as confirmed in Toronto Electric Commissioners v Snider, [1925] AC 396 (PC):

• Part I — Industrial Relations (ss. 3–126): collective bargaining, union certification, unfair labour practices, and dispute resolution.
• Part II — Occupational Health and Safety (ss. 122–161): workplace hazard prevention, internal responsibility system, work refusals, and anti-reprisal protections.
• Part III — Labour Standards (ss. 162–267): individual employment rights, hours of work, wages, leaves of absence, termination, and severance.

Part I — Industrial Relations

Part I of the Code establishes the legal framework for collective bargaining in the federal sector. It is administered by the Canada Industrial Relations Board (CIRB), replaced the former Canada Labour Relations Board under the Code Reorganization Act, 1998. The CIRB is a specialized quasi-judicial tribunal with exclusive jurisdiction over certification, unfair labour practices, and collective agreement interpretation.

Union certification under ss. 24–32 requires a union to demonstrate majority support in a bargaining unit appropriate for collective bargaining. The CIRB may order a representation vote (mandatory if at least 35% of employees have union membership evidence) and certifies the union if a majority of votes cast support the application. Once certified, the union has exclusive bargaining authority and is subject to a duty of fair representation (s. 37) owed to all employees in the unit.

Collective bargaining is governed by good faith requirements: both parties must meet and make every reasonable effort to enter into a collective agreement (s. 50(a)). Impasse resolution includes conciliation (the Minister may appoint a conciliation officer or commissioner under ss. 70–80), mediation, and ultimately strike or lockout (permissible only after the collective agreement expires, the conciliation process is exhausted, and the required 72-hour notice of strike or lockout is given under s. 87.2). The Code prohibits strikes and lockouts during the term of a collective agreement (s. 88).

The right to strike is constitutionally protected under s. 2(d) of the Canadian Charter of Rights and Freedoms (Saskatchewan Federation of Labour v Saskatchewan, 2015 SCC 4; Mounted Police Association of Ontario v Canada (AG), 2015 SCC 1). The Code’s strike provisions had historically restricted the right to strike for certain public sector employees (e.g., air traffic controllers, grain handlers). Post-2015, the CIRB has recognized that absolute prohibitions on striking must satisfy s. 1 justification; essential service designations (s. 87.4) continue to limit the right for employees whose duties are necessary to prevent “immediate and serious danger” to public safety, but Amalgamated Transit Union (CIRB, 2016) held that essential service designations must be minimal in scope.

Successor rights (s. 44) protect the bargaining rights and collective agreement when a business is sold, leased, or transferred — a provision interpreted broadly in Construction Montcalm Inc v Commission du salaire minimum, [1979] 1 SCR 754, and applied in the federal sphere in Westcan Bulk Transport Ltd v CIRB, 1998 CanLII 9106 (FCA). Common employer declarations (s. 35) allow the CIRB to treat multiple corporations as a single employer for labour relations purposes.

First contract arbitration (s. 80.1) is available where the parties cannot reach agreement despite conciliation; the Minister may refer the matter to the CIRB to impose a first collective agreement.

Part II — Occupational Health and Safety

Part II of the Code establishes the internal responsibility system (IRS), a foundational principle of Canadian OHS law articulated by the Royal Commission on the Health and Safety of Workers in Mines (the Burkett Report). The IRS posits that workplace parties — employers, supervisors, and employees — share responsibility for health and safety. The employer’s general duty (s. 124) requires that every employer ensure the health and safety of employees at work, a duty that the Federal Court of Appeal has held is near-absolute (Canada Labour Code, Canada (AG) v Canada (Human Rights Commission), 2004 FCA 289).

Key Part II mechanisms include:

• Workplace committees (Policy Health and Safety Committees for 300+ employees, Workplace Health and Safety Committees for 20+ employees, and Health and Safety Representatives for under 20 employees under ss. 134–136) with co-chair from management and labour.
• Work refusals (s. 128): any employee who believes that a situation constitutes a “danger” (defined in s. 122(1) as any hazard, condition, or activity that could reasonably be expected to cause injury or illness before the hazard can be corrected) may refuse to work. The exercise of the right is procedurally structured: the employee reports to the supervisor, an investigation occurs, and if the matter is unresolved, a health and safety officer investigates and issues a direction. The Supreme Court in Canadian Union of Postal Workers v Canada Post Corp, 2018 SCC 55 confirmed that the work refusal right extends to psychological danger where there is a reasonable expectation of workplace violence or harassment.
• Anti-reprisal provisions (s. 147): employers cannot discipline or dismiss employees for exercising Part II rights. The CIRB has held that the burden shifts to the employer to demonstrate that the discipline was unrelated to the OHS activity (Bisaillon v Concordia University, 2006 FCA 15).
• Harassment and violence prevention (ss. 122–122.1, supplemented by the Work Place Harassment and Violence Prevention Regulations, SOR/2020-130): employers must develop and implement a prevention policy, conduct workplace risk assessments, and maintain a resolution process for occurrences of harassment and violence. The regime replaced former “violence” provisions in 2021.

Health and safety officers (designated under s. 140) have broad inspection powers, including warrantless entry, seizure, and direction-issuing authority (s. 145). Contravention of a direction may lead to orders under s. 145(5), prosecution (s. 148), and penalties of up to CA$1,000,000 for corporations and CA$300,000 or up to two years imprisonment for individuals (s. 148).

Part III — Labour Standards

Part III establishes minimum employment standards for federally regulated employees, enforceable through the Federal Labour Standards Directorate within the Labour Program of Employment and Social Development Canada. Key provisions include:

Hours of work (ss. 169–177): the standard workweek is 40 hours (s. 169(1)), with overtime at 1.5 times the regular rate for hours worked in excess of 40 (s. 174). Maximum hours are 48 per week (s. 171), subject to permit exemptions. Minimum wage (s. 178) is established by regulation (federal minimum was CA$17.30 per hour as of 2026, adjusted annually by CPI).

Leaves of absence include: maternity leave (s. 205, 17 weeks), parental leave (s. 206, 63 weeks available to either parent or shared), compassionate care leave (s. 206.1, 28 weeks), sick leave (s. 239, 10 days of medical leave with no medical certificate required for 3-day absences, 3 days of personal leave, and up to 17 weeks of medical leave for long-term illness), bereavement leave (s. 210, 10 days), leave for victims of family violence (s. 206.4, 10 days), and reservist leave (s. 247.6, unlimited for CAF reserve service). Bill C-3 (2022) amended the Code to provide for up to 10 days of paid medical leave for federal employees, the first paid sick leave requirement in the Code’s history.

Termination of employment: for individual non-unionized employees with at least three months of continuous employment, the employer must provide notice of termination (s. 230): two weeks for 3 months to 2 years, two weeks plus one additional week per completed year of service for 2 years to 8 years, and eight weeks for 8+ years. Alternatively, the employer may pay wages in lieu of notice. Severance pay (s. 235) is required for employees with 12+ months of service where the employer has a payroll of CA$2.5 million or more: two days’ wages per completed year of service, to a maximum of 26 weeks’ wages. Mass termination provisions (s. 212) require extended notice (8–16 weeks) where 50+ employees are terminated within a four-week period and impose obligations on employers to provide information and severance beyond the minimum.

Unjust dismissal (s. 240) provides a quasi-adjudicative remedy for non-unionized employees with at least 12 months of continuous service who are not subject to a collective agreement. An adjudicator appointed under s. 242 may reinstate the employee (with back pay) or award damages in lieu. The regime has been held to be a mandatory alternative to civil wrongful dismissal action (Wilson v Atomic Energy of Canada Ltd, 2016 SCC 29, confirming that the Code ousts the common law cause of action for wrongful dismissal for employees within Part III’s scope).

Related Tribunals and Enforcement

The Code’s three Parts are overseen by distinct tribunals: the CIRB (Part I), health and safety officers and the Occupational Health and Safety Tribunal Canada (Part II), and the Federal Labour Standards Directorate with de novo review by the Federal Court (Part III; unjust dismissal adjudicators are appointed under s. 242). The three regimes operate independently but share a coherent constitutional foundation in federal power over interprovincial and international matters, as delineated in Snider and confirmed in Northern Telecom Ltd v Communications Workers of Canada, [1983] 1 SCR 733.

Relationship with Provincial Labour Law

The Code’s application is determined by the functional and operational test: an undertaking is subject to federal jurisdiction if its operations are an “integral part” of a federal work or undertaking (Canadian Broadcasting Corp v Canada (Labour Relations Board), [1985] 1 SCR 496; NIL/TU,O Child and Family Services Society v BC Government and Service Employees’ Union, 2010 SCC 45). Where employees are subject to the Code, provincial employment standards, labour relations, and OHS laws do not apply, though provincial human rights codes (which are quasi-constitutional and apply to all employers, including federal) continue to govern non-discrimination and accommodation (Bell Canada v Quebec (Commission des droits de la personne), 2018 SCC 5).
