In the Mercure and Paquette cases, the Supreme Court of Canada confirms bilingualism in Saskatchewan and Alberta

The Court recognizes that section 110 of the Northwest Territories Act still applies to those provinces.

However, it also stated that they could legislate on official languages matters as a result of the amendment made in 1891 to the Northwest Territories Act.

To avoid being subject to the same language policy as Manitoba, Saskatchewan and Alberta adopted the Act Respecting the Use of the English and French Languages in Saskatchewan and the Languages Act, respectively, which revoked most of the historical rights of their linguistic minorities.
