« According to the 2011 Census, 17.5% of the Canadian population, or 5.8 million Canadians, reported being able to conduct a conversation in both English and French. Between the 2001 and 2011 censuses, this proportion declined slightly for the first time after four successive decades of growth.
In 1961, the English–French bilingualism rate was 12.2%. Subsequently, it rose in every decade to a peak of 17.7% in 2001.
In the last decade, the total population increased faster than the bilingual population for the first time since 1961.
As a result, although the number of bilingual Canadians increased from 5.2 million in 2001 to 5.8 million in 2011, their share as a percentage of the total population declined slightly over the period, from 17.7% to 17.5%. »
