DWI,
According to the 2011 census, the last statistics available, francophones were 22% of Canada's population.  The federal civil service has consistently been 29% (or more) francophone over the past 35 years (https://www.canada.ca/en/treasury-board-secretariat/services/innovation/human-resources-statistics/demographic-snapshot-federal-public-service-2014.html).  For 40 of the past 50 years, the country's PM has been Montreal-born/-based.  Credit to Clark and Harper for their language skills in spite of their roots, but they are outliers.
