Saskatchewan's essential services legislation gave public employers significant power to designate employees who could not participate in strike activity. Unions challenged the restrictions, arguing that the scheme interfered with meaningful collective bargaining. The litigation also raised a separate challenge to amendments governing union certification and related labour relations matters.
In Saskatchewan Federation of Labour v. Saskatchewan, 2015 SCC 4, a majority of the Supreme Court of Canada concluded that the freedom of association protected by section 2(d) of the Charter includes the right to strike. The Court treated the capacity to withdraw labour collectively as an essential component of meaningful collective bargaining, rather than an activity wholly outside constitutional protection.
The government could pursue legitimate objectives such as protecting essential public services. The problem was how the statute pursued them. The legislation permitted broad designations and didn't adequately provide for independent review or a meaningful alternative dispute resolution process for workers whose strike rights were removed. In the majority's view, those features substantially interfered with collective bargaining and couldn't be justified under section 1 of the Charter on the record before it.
The Court invalidated the Public Service Essential Services Act, suspending the declaration of invalidity for one year to allow a legislative response. The separate challenge to the Trade Union Amendment Act was unsuccessful. Two judges dissented in part, expressing concerns about constitutionalizing a right to strike and the policy consequences for legislatures.
The decision doesn't mean all strikes are unlimited or that essential services can never be protected. It means a restriction that substantially removes workers' economic leverage must be justified in a constitutional framework, with particular care where employees have no workable alternative for resolving bargaining disputes.
The practical significance extends beyond Saskatchewan. Legislators, public employers and unions need to examine whether any essential services designation process is independent, proportionate and paired with meaningful dispute resolution. The case sets a constitutional foundation, while the validity of a specific modern regime still depends on its own legislative design and evidence.
