Overview
The Ontario Court of Appeal’s decision in Ontario Public Service Employees Union v. Ontario (Attorney General), 2026 ONCA 74, provides important guidance for unionized employers and public sector stakeholders considering the constitutional risks and limits of back-to-work legislation.
The case arose from Ontario’s 2017 college faculty strike. After five weeks of strike action, the province enacted the Colleges of Applied Arts and Technology Labour Dispute Resolution Act, 2017, which ended the strike and sent the remaining bargaining issues to binding interest arbitration. The Ontario Public Service Employees Union challenged the legislation as an unjustified infringement of freedom of association under s. 2(d) of the Charter. The challenge failed at first instance, and the Court of Appeal dismissed the appeal.
The Court Confirmed That Ending a Lawful Strike Limits s. 2(d) Rights
The Court of Appeal held that legislation ending a properly called strike necessarily and substantially interferes with meaningful collective bargaining. In the Court’s view, the right to strike is an essential component of the collective bargaining process protected by s. 2(d).
That conclusion is significant because it confirms that back-to-work legislation is not constitutionally neutral simply because it responds to a labour dispute. Where legislation removes the ability to continue lawful strike action, it will attract Charter scrutiny and must be justified under s. 1.
Why the Legislation Was Still Upheld
Although the legislation limited OPSEU members’ freedom of association rights, the Court found that Ontario had justified the infringement in the circumstances of the case.
The province’s objective was to resume instruction at Ontario’s 24 colleges and protect students from serious academic, financial, and personal harm caused by the prolonged interruption to the academic term. The Court accepted that this was a pressing and substantial objective.
The Court also found that the legislation was rationally connected to that objective. Ending the strike was directly related to restoring instruction and reducing the harm to students.
On minimal impairment, the Court accepted that the legislation did not simply terminate the strike and leave the parties without a dispute-resolution process. Instead, it referred the unresolved issues to neutral interest arbitration. That process was unrestricted, and the legislation did not dictate the collective agreement outcome.
Finally, the Court found the overall balance proportionate. The harm to students from a lengthy strike was serious, while the legislation preserved a meaningful alternative mechanism for resolving the dispute.
The Role of Neutral Interest Arbitration
A key feature of the Court’s analysis was the availability of neutral, unrestricted interest arbitration. The Court accepted that this substitute process mitigated the impact of ending strike action because it preserved a meaningful avenue for resolving the outstanding bargaining issues.
For the Court, the fact that no outcomes were predetermined mattered. The legislation did not remove the disputed issues from consideration, and it did not impose the employer’s preferred terms by legislative fiat. Instead, it required the parties to proceed through a neutral process designed to resolve the dispute fairly.
For employers, this aspect of the decision is important. It suggests that where governments intervene in a labour dispute, the constitutional risk may be reduced if the legislation provides a genuine and fair alternative to strike action rather than simply extinguishing the dispute on one side’s terms.
What Unionized Employers Should Take From the Decision
This decision does not mean that back-to-work legislation will always be upheld. The Court confirmed that such legislation does limit s. 2(d) rights and will be closely examined under the Charter. However, the case shows that legislation may still survive constitutional review where the government can demonstrate the following:
-
a serious and pressing public objective;
-
clear evidence of harm if the strike continues;
-
a rational connection between ending the strike and addressing that harm;
-
a fair and effective substitute dispute-resolution process; and
-
no predetermined outcome that strips the bargaining process of meaning.
For unionized employers, the practical lesson is that labour disputes involving essential public services, educational continuity, or significant third-party harm may create circumstances in which back-to-work legislation is more likely to withstand challenge. At the same time, the legislation must be carefully structured. The presence of a neutral arbitration process was central to the Court’s conclusion that the infringement was justified.
Why the Decision Matters in the Employment Law Context
Although the case involved a public sector college strike, the Court’s reasoning is relevant more broadly to employers and institutions operating in unionized environments. It reinforces that the right to strike is constitutionally protected, but not absolute. It also confirms that governments may intervene where the public interest is sufficiently strong and where the legislation preserves a meaningful path to resolve the underlying bargaining dispute.
For employers, this is a reminder that labour disputes can raise both operational and constitutional issues. Where a strike affects students, patients, residents, or other vulnerable third parties, the legal and practical stakes increase quickly. Careful advice is often needed before, during, and after any legislative intervention.
Conclusion
The Ontario Court of Appeal concluded that legislation ending a lawful strike does limit unionized employees’ freedom of association under s. 2(d) of the Charter because the right to strike is an essential part of meaningful collective bargaining. However, the Court held that the infringement was justified under s. 1 in this case. Ontario had a pressing and substantial objective: resuming instruction at Ontario’s 24 colleges and mitigating serious harm to students caused by a lengthy interruption to the academic term. The legislation was rationally connected to that objective, minimally impairing, and proportionate because it referred unresolved bargaining issues to a neutral interest arbitration process where no outcomes were predetermined or removed from consideration.
For unionized employers, the decision confirms that back-to-work legislation will attract Charter scrutiny, but may be upheld where the government can demonstrate serious public harm, reasonable timing, and a fair, effective substitute process for resolving the labour dispute.
