In two decisions released only two weeks apart, the Supreme Court of Canada has clearly moved to “refang” the union movement, especially insofar as it involves government employers. In its first decision of the year, Mounted Police Association of Ontario v. Canada (Attorney General), 2015 SCC 1, the majority of the Court ruled that the laws prohibiting RCMP members from being able to freely organize their own independent labour association (ie. a labour union) contravened their freedom of association as protected by s. 2(d) of the Charter and could not be justified under s. 1. In last Friday’s decision, Saskatchewan Federation of Labour v. Saskatchewan, 2015 SCC 4, a majority of the Court held that Saskatchewan’s “essential services” laws which prohibit the public service from striking were similarly contrary to s. 2(d) and unconstitutional. In both cases, Justice Rothstein (joined by Justice Wagner in the second decision) provided powerful dissents. As a result of these decisions and other relatively recent decisions, Canada constitutional protection of freedom of association has now come to protect core elements of labour relations, such as the right to bargain collectively, the right to strike and the right to freely choose an independent labour association to represent their interests viz-a-viz the employer. We have come a long, long way from the labour trilogy of 1987.

In 1987, a majority of the Supreme Court of Canada held that “the constitutional guarantee of freedom of association in s. 2(d) of the Canadian Charter of Rights and Freedoms does not include, in the case of a trade union, a guarantee of the right to bargain collectively and the right to strike”: Reference Re Public Service Employee Relations Act (Alta),  1 SCR 313, per Le Dain J. Then, after testing the waters in some earlier cases, the Supreme Court of Canada reversed this ruling in 2007 in Health Services and Support – Facilities Subsector Bargaining Assn. v. British Columbia, 2007 SCC 27, at para. 86:
“We conclude that the protection of collective bargaining under s. 2(d) of the Charter is consistent with and supportive of the values underlying the Charter and the purposes of the Charter as a whole. Recognizing that workers have the right to bargain collectively as part of their freedom to associate reaffirms the values of dignity, personal autonomy, equality and democracy that are inherent in the Charter.”
While the constitutional status of the right to strike is now in doubt, there is no doubt that the courts, with the Supreme Court of Canada leading the way, are resetting the constitutional balance of power between trade unions on one hand and employer (and especially public sector employers) on the other.
