Many of the documents in Canada's Constitution do not have an official French-language version; for legal purposes only the English-language version is official and any French translations are unofficial. In particular, the "Constitution Act, 1867" (which created Canada as a legal entity and still contains the most important provisions of governmental powers) has no official French-language version because it was enacted by the United Kingdom Parliament, which functions in the English language exclusively. Similarly, all other parts of the Constitution that were enacted by the United Kingdom (with the important exception of the "Canada Act 1982") have no official French-language version.
