Ontario Collective Bargaining Guide 2024

The Collective Bargaining Framework in Ontario

Ontario collective bargaining is governed by the Labour Relations Act, 1995 (LRA) for the private sector and broader public sector (universities, school boards, municipalities, and broader public sector employers). Separate legislation governs specific public sector groups: the Hospital Labour Disputes Arbitration Act (HLDAA) for hospital workers; the Police Services Act for police; and the Crown Employees Collective Bargaining Act (CECBA) for Ontario public service employees.

The Ontario Labour Relations Board (OLRB) is the administrative tribunal with jurisdiction over most private sector and broader public sector collective bargaining — certifying unions, adjudicating unfair labour practices, ordering remedies, and supervising the bargaining process.

Union Certification Under the LRA

Certification is the legal process by which a trade union gains the exclusive right to bargain collectively on behalf of a group of employees (the bargaining unit). Ontario certification under the LRA:

Membership Evidence (s.7)

To file a certification application, the union must have 40% membership support from employees in the proposed bargaining unit — demonstrated through signed membership cards or dues deduction authorizations. The 40% threshold is required to trigger the certification application; it is not the threshold for certification.

The membership bar: An employer may not make any changes to terms and conditions of employment without the union's consent during the period between the filing of the certification application and the conclusion of bargaining or certification proceedings.

Bargaining Unit Determination

The OLRB determines the appropriate bargaining unit — the group of employees the union will represent. The LRA requires the bargaining unit to be “appropriate for collective bargaining.” Factors include: community of interest among employees; the nature of the work performed; geographic considerations; the existing organization of the enterprise; and past bargaining history.

Bargaining unit composition is strategic for both unions and employers. A broad unit may include employees with diverse interests who are difficult to organize. A narrow unit may exclude employees the union wants to include. The OLRB has significant discretion in determining the appropriate unit.

Secret Ballot Vote (s.14)

Ontario uses a mandatory secret ballot for certification — if the union demonstrates 40% membership support, the OLRB directs a representation vote. A majority of employees voting in favour results in certification. The vote is supervised by the OLRB and must occur within 5 business days of the application (expedited vote) for most sectors.

Prior to 2008, Ontario used a card-check system (automatic certification on 55%+ card signing). The current mandatory vote system means unions must win a secret ballot vote even with high card support — campaigns by both the employer and the union during the vote period can influence the result.

The Duty to Bargain in Good Faith (s.17)

Once certified, the employer and the union must bargain collectively. Section 17 of the LRA imposes the duty to bargain in good faith:

“Every trade union or council of trade unions, so long as it continues to be entitled to represent the employees in a bargaining unit, and every employer of such employees shall bargain collectively in good faith and make every reasonable effort to make a collective agreement.”

Components of Good Faith Bargaining

Good faith bargaining requires substantive and procedural good faith:

• Meeting and bargaining: Parties must actually meet, at reasonable times and places, to negotiate
• Genuine consideration: Proposals must be genuinely considered — not summarily dismissed without explanation
• Disclosure: Relevant financial information must be disclosed if the employer pleads inability to pay
• No surface bargaining: Going through the motions of negotiation without genuine intent to reach an agreement violates the duty — the OLRB looks at the overall pattern of conduct, not isolated incidents
• No unilateral changes: The employer cannot unilaterally change terms and conditions of employment during bargaining without union consent

Collective Agreement Terms and Duration

A collective agreement in Ontario must be in writing and signed by both parties. Under the LRA, a first collective agreement must be for a term of at least 1 year. The agreement binds the employer and all employees in the bargaining unit for its duration. Collective agreements in Ontario typically run for 2 to 4 years.

Upon expiry of a collective agreement, the parties bargain for renewal. During the statutory freeze period (after the collective agreement expires and during bargaining), the employer cannot change the terms and conditions of employment without union consent. The freeze period prevents employers from unilaterally changing wages or benefits to undermine the union's bargaining position.

Strikes and Lockouts Under the LRA

In the private sector (and most broader public sector), strikes and lockouts are the ultimate economic pressure tools for resolving bargaining impasses. Under the LRA, a strike or lockout is lawful only after:

• The collective agreement has expired (or 30 days have passed from notice to bargain)
• A conciliation officer has been appointed and a no-board report has been issued (the Ministry of Labour appoints a conciliator; if no agreement is reached, a no-board report issues, starting the countdown)
• 17 days have passed after the no-board report (the “cooling off” period)
• The union has held a strike vote — a majority of employees voting in favour of strike action within 30 days before the strike

Striking employees retain their status as employees — they cannot be permanently replaced in Ontario (unlike the US). The employer may hire temporary replacements during a strike but must reinstate strikers when the strike ends.

Interest Arbitration in Ontario

Interest arbitration — where an arbitrator imposes the terms of a collective agreement on parties who cannot agree — is generally not available in Ontario's private sector. Private sector parties resolve impasses through negotiation, conciliation, and ultimately strike or lockout.

Interest arbitration is mandatory in designated essential service sectors:

• Hospitals under the Hospital Labour Disputes Arbitration Act — strikes and lockouts in hospitals are prohibited; disputes go to binding interest arbitration
• Police under the Police Services Act — strikes by police are prohibited; interest arbitration is mandatory
• Fire services under the Fire Protection and Prevention Act
• Crown employees under the CECBA — with complex rules about essential services designations
• Certain transit services — strike/lockout restrictions apply

Interest arbitrators in Ontario use several methodologies: internal comparisons (looking at settlements within the same sector or employer), external comparisons (looking at comparable bargaining units in other sectors), ability to pay, and the public interest. Hospital arbitrations under the HLDAA have generated a substantial jurisprudence on interest arbitration principles.

First Collective Agreement Arbitration (s.43)

LRA s.43 provides a safety net for newly certified unions: either party may apply to the OLRB for first collective agreement arbitration where the parties have bargained for the prescribed period without reaching an agreement.

The OLRB will order first agreement arbitration if it considers it advisable, having regard to whether:

• The failure to conclude a first agreement is the result of unreasonable conduct by either party
• A strike or lockout has occurred
• The employer has engaged in unfair labour practices
• The parties have bargained for a substantial period without progress

First agreement arbitration is an important remedy — it prevents employer strategies of delaying, blocking, or sabotaging the first collective agreement to frustrate the union's organizational victory.

Unfair Labour Practices Under the LRA

The LRA prohibits conduct that interferes with employees' rights to organize and bargain collectively:

Employer Unfair Labour Practices (s.70)

• Participating in or interfering with the formation or administration of a trade union
• Discriminating against an employee because of union membership or activities
• Threatening or coercing employees in relation to union activities
• Refusing to bargain collectively in good faith
• Bargaining with a union other than the certified union

Trade Union Unfair Labour Practices (s.76)

• Coercing or intimidating employees to join the union
• Discriminating against employees in union membership administration
• Breach of the duty of fair representation (s.74) — the union must represent all bargaining unit employees fairly, regardless of their union membership status

Frequently Asked Questions

How does the union certification process work in Ontario?

The union files a certification application with the OLRB demonstrating 40% membership support. The OLRB determines the appropriate bargaining unit and directs a secret ballot vote. A majority voting in favour results in certification. Employers cannot make threats or promises during the organizing campaign — only factual information is permitted.

What is the duty to bargain in good faith in Ontario?

LRA s.17 requires employer and union to bargain in good faith and make every reasonable effort to reach a collective agreement — meeting regularly, genuinely considering proposals, disclosing relevant information, and not surface bargaining (going through motions without intent to agree).

What is interest arbitration in Ontario collective bargaining?

Interest arbitration (arbitrator-imposed collective agreement terms) is generally not available in Ontario's private sector. It is mandatory for hospitals (HLDAA), police (Police Services Act), fire services, and certain transit services where strikes and lockouts are prohibited as essential services.

What is first collective agreement arbitration in Ontario?

Under LRA s.43, either party may apply to the OLRB for first agreement arbitration if the parties have bargained without reaching agreement. The OLRB may order arbitration where the failure is due to unreasonable conduct, bad faith, or unfair labour practices — protecting newly certified unions from employer strategies to block the first collective agreement.

What are unfair labour practices under the Ontario Labour Relations Act?

Employer unfair labour practices include interfering with union formation, discriminating against union members, coercing employees, and refusing to bargain in good faith (LRA s.70). Trade union unfair labour practices include coercing employees to join, discriminating in membership administration, and breaching the duty of fair representation (LRA s.74 and s.76).
