I would add that francophones are also assimilating. francophones who anglicize join the anglophone population and leave the francophone population.
This kind of linguistic assimilation is occurring at twice the rate and has twice as many consequences as the anglicization or francization of a person whose mother tongue is a non-official language.
I would also point out that Statistics Canada's 2017 projection work does not reflect the accelerating anglicization of francophone young adults on Montreal Island, whom I mentioned in my brief and discussed this evening.
With respect to linguistic assimilation, these projections are based solely on 2001 and 2006 census data. They're already out of date and invalid. The exercise has to be redone based on new data from the 2011 and 2016 censuses.
