Absolutely. It's a huge challenge, because we know full well that for immigrants, it's not because you have another language as a mother tongue or that you speak that other language most often at home that you won't have a preference for English or won't turn towards English.
The language used in the public space is definitely a challenge. Perhaps the greatest challenge is to cope with this form of bilingualization that is becoming relatively widespread in the greater Montreal area. What needs to be done is to try and understand why it is happening.
