The assimilation issue dates back a long time. I remember that, when I was at Waskesiu, I had visited all of Saskatchewan in 1965 and all of Alberta in 1966. I went to Saint-Albert. There was an anniversary, and Mayor Van Brabant gave me a book to mark the anniversary of Saint-Paul. Naturally the book had to be paid for. There were sponsors named in the book. They were typically local businesses. They showed the progress they had made by means of a photograph taken in 1905 and another one taken in 1965. You could see all the progress that had been made. Obviously, the building was bigger, but the signage had also changed. Although the family name was still the same, the description was in English. That was progress. I saw that in 1967. So I can imagine how it might be today.
However, there are two things: there are new francophones going to those provinces, and there are anglophones who are becoming francophiles.
