In the 2001 Census, 22.9% of Canadians had French as their mother tongue, 59.1% English, and 18% neither of the two official languages. Mother tongue is defined as the first language a person learned at home in childhood and still understood at the time of the census. A person with both English and French mother tongue learned both languages at home equally and still understands both. Persons whose mother tongue is neither English or French, in combination with one non-official language, or have neither English or French mother tongue fall in the other language group.
