Final answer:
The rights of Canadians regarding official languages are protected by the Constitution Act of 1867, the Official Languages Act of 1969, and the Charter of Rights and Freedoms of 1982, which ensure that both English and French have official status at the federal level, with additional protections for French in Quebec.
Step-by-step explanation:
The legal documents that protect the rights of Canadians with regard to the official languages include the Constitution Act of 1867, the Official Languages Act of 1969, and the Charter of Rights and Freedoms enacted in 1982. The Constitution Act established English and French as the official languages of the Parliament and the federal courts in Canada. The Official Languages Act was passed to ensure that federal institutions operate in both official languages, and the Charter of Rights and Freedoms guarantees individual rights to communicate with and receive services from federal institutions in either official language. Additionally, in Quebec, French is the only official language as protected by provincial legislation, specifically Bill 101, the Charter of the French Language. These documents together form a framework to ensure language rights are observed nationally and provincially, preserving the French culture within Quebec while also providing services in English.
