The passage of the Canadian Charter of Rights and Freedoms in 1982 allowed for the provision of challenging the constitutionality of laws governing prostitution law in Canada in addition to interpretative case law. Other legal proceedings have dealt with ultra vires issues (whether a jurisdiction, such as a Provincial Government or municipality, has the powers to legislate on the matter). In 2013, three provisions of the current law were overturned by the Supreme Court of Canada, with a twelve-month stay of effect. In June 2014, the Government introduced amending legislation in response.
The new formulations of section 213 found themselves under challenge in the lower courts within a year, with conflicting results (R. v. McLean, 28 C.C.C. (3d) 176 (1986). ; R. v. Bear, 54 C.R. (3d) 68 (1986). ).
Nova Scotia's Appeal Court ruled the legislation violated the guarantee of freedom of expression in the Charter of Rights and Freedoms, by constraining communication in relation to legal activity (R. v. Skinner (1987), 35 C.C.C. (3d) 203). The Alberta Court of Appeal disagreed, holding that infringement of freedom of expression was a justifiable limitation as no “clear and convincing” alternative was available for dealing with the nuisance of street prostitution (R. v. Jahelka (1987), 79 A.R. 44).
The Manitoba Court of Appeal upheld section 195.1(1)(c) on the grounds that there was no prima facie case of freedom of expression (Reference Re Sections 193 and 195.1(1)(c) of the Criminal Code, [1987] 6 W.W.R. 289).
When referred to the Supreme Court, it upheld the sections (Reference Re Sections 193 and 195.1(1)(c) of the Criminal Code, [1990] 1 S.C.R. 1123])Chief Justice Dickson for the majority (Madam Justice Wilson and Madam Justice L'Heureux‑Dubé dissenting), agreed that freedom of expression was restricted by what was now 213(1)(c) it did not infringe or deny the freedom of association guaranteed by section 2(d) of the Charter. He also held that it did not infringe the right to be treated fairly when life, liberty and security are affected by governmental action, as guaranteed by section 7 of the Charter. The reference to the court also included the bawdy house provisions which were held to not infringe the guarantee of freedom of expression provided for by section 2(b) of the Charter. Finally the impugned infringement of the freedom of expression guaranteed by section 2(b) of the Charter was justifiable under section 1 of the Charter as being a reasonable limit on a protected right.
