Following the pandemic, we observed a slowdown in enrolment in French immersion programs in a number of places. In some places, the requirement to teach French is being removed, especially in certain rural school boards. That's why the proportion of students living outside Quebec who are enrolled in a French as a second language program has risen to 45%. It used to be higher.
I don't know if it's because of a drop in interest, but the teacher shortage is certainly a factor. In core French alone, there is a shortage of 7,000 to 8,000 teachers, which puts a lot of pressure on school authorities, if only to offer the programs. So I would say it's more a lack of resources than a drop in interest.
