Actually, yes, there is a limitation, which is the language of the survey. We survey only in both official languages. In the case of the immigrant population, it's true that we don't get some specific populations that could be more vulnerable because they might be more isolated because they don't speak one of the languages. Still, these are a minority among immigrants. We still think we capture most immigrants, and the numbers are much lower for immigrants. However, when we look at second generation, the numbers are no longer lower for second-generation immigrants.
