Just for summary, then, if I get it right, the program was established in 1978 and had the linguistic character, essentially, first; then there was the Charter of Rights and Freedoms in 1982 for the other rights. It wouldn't be unfair to say—this would be a sort of yes or no thing, because of the time—that this was first a program for the protection of entrenched language rights in the Constitution, and then because of the passage of time and new developments, it became a program for the protection of other rights.
