Absolutely.
In fact, they will integrate better. That said, for that to happen, we need a critical mass. You can't do it one immigrant at a time. That's why the cohort idea is really important. People integrate better as a group than as individuals.
If we can help these immigrants settle in areas such as St. Marys Bay, where life is still lived in French, we would give this community a better chance of survival, but we would also give these people a better chance of integrating as part of the larger Canadian francophone family, of course.
