The ACPPA requires AC to respect the Official Languages Act
The same rules do not apply to other Canadian carriers
Section 10 of the ACPPA prescribes that Air Canada is subject to the Official Languages Act, or the OLA, and is therefore considered a federal institution pursuant to the OLA. Air Canada is the only Canadian airline that is subject to obligations under the OLA. It has been subject to the OLA since 1969, including part IV, covering the communications with and services to the public; part V, covering the language of work; part VI, covering the participation of English-speaking and French-speaking Canadians; and part VII, covering the advancement of English and French.
Other major Canadian airlines, such as WestJet, Air Transat, Porter Airlines, and Sunwing, are not subject to the same obligations as Air Canada under the ACPPA or the OLA. However, all major airlines must provide safety instructions to their passengers in English and in French under the Canadian Aviation Regulations pursuant to the Aeronautics Act, which also falls under the responsibility of the Minister of Transport.
It should be noted that Air Canada does not receive any direct or indirect funding from the federal government for its linguistic training programs, the language assessments of its employees, or its bilingual communications activities. Nevertheless, the airline allocates significant resources, both financial and human, to develop and maintain its linguistic programs and internal tools to meet its obligations under the OLA.
