Adler v Ontario, [1996] 3 S.C.R. 609 is a leading decision of the Supreme Court of Canada on the nature of the provincial education power and whether there was a constitutional obligation to fund private denominational education. The Court found that Ontario's Education Act did not violate sections 2(a) or 15(1) of the Canadian Charter of Rights and Freedoms or section 93 of the Constitution Act, 1867.
The guarantees provided for religious freedom under sections 2(a) and religious equality under section 15(1) of the Charter were used to argue that lack of government funding for Jewish Canadian schools and certain Christian schools in Ontario was unconstitutional, since by contrast Catholic schools received government funding in accordance with section 93 of the Constitution Act, 1867. The court was asked to address two specific constitutional issues:
The ruled 7–1 on the first question, and 6–2 on the second, that the provisions in question were constitutional. L'Heureux‑Dubé J. dissented on both questions, and McLachlin J. dissented in part on the first question, and in full on the second.
The majority of the Court held that the provincial education power under section 93 of the Constitution Act, 1867 is plenary, and is not subject to Charter attack. As Iacobucci J. noted, it is the product of a historical compromise crucial to Confederation and forms a comprehensive code with respect to denominational school rights which cannot be enlarged through the operation of s. 2(a) of the Charter. It does not represent a guarantee of fundamental freedoms. The appellants, given that they cannot bring themselves within the terms of s. 93's guarantees, have no claim to public funding for their schools. To decide otherwise by accepting the appellants' claim that s. 2(a) requires public funding of their dissentient religion‑based schools would be to hold one section of the Constitution violative of another.
The claim that the government's choice to fund Roman Catholic separate schools but not other religious schools contravened the equality provisions of s. 15(1) of the Charter should be rejected for two reasons:
There was a difference in interpretation as to how far the education power can extend towards the establishment of other education systems. The majority believed that legislation in respect of education could be subject to Charter scrutiny whenever the government decides to go beyond the confines of this special mandate to fund Roman Catholic separate schools and public schools. Sopinka J., on the other hand, observed that nothing in s. 93(3) restricts extending funding to others. However, when the province exercises its plenary power outside of the areas specified in s. 93(1) and (3), any distinctions violating the Charter are not "expressly permitted" or even contemplated. Legislation in such cases is no different from legislation under any of the heads of s. 92. Giving effect to the Charter will not invalidate any power conferred by s. 93.
McLachlin J. stated that Section 93 is not a code ousting the operation of the Charter and was not intended to do more than guarantee school support for the Roman Catholic or Protestant minorities in Ontario and Quebec respectively. Provinces exercising their plenary powers to provide education services must, subject to this restriction, comply with the Charter. Otherwise, she considered the provisions in question to be constitutional.
L'Heureux‑Dubé J. declared that the only school support guaranteed by s. 93 is that required of Ontario and Quebec to their respective Roman Catholic and Protestant minorities. Provinces exercising their plenary powers to provide education must, subject to this requirement, comply with the Charter. The provisions survived a challenge under Section 2, but ought to fail under Section 15.
Both Iacobucci J. and Sopinka J. held that the School Health Support Services Program in question is immune from Charter scrutiny, as it is properly characterized as an "education service", as opposed to a "health service", and thus falls within the plenary education power.
In dissent, both McLachlin J. and L'Heureux‑Dubé J. felt that the Program should not survive a Section 15 Charter challenge, as the denial of the health support program to the independent schools is not rationally connected to the objectives of providing universal education without discrimination, and is not justifiable under Section 1.
