Why is that a problem? Languages and culture change all the time. Iceland is hardly "Iceland" anymore compared to any sufficiently past "Iceland" (e.g. pre-Internet, pre-aviation, pre-motor vehicles, etc) but I don't see any reason why that is a bad thing in principle. This seems an odd concern to be raised in a language that can charitably be described as the bastard child of Norse and French mostly spoken by people who never sat foot in Great Britain. You also seem to assume all of those immigrants are culturally and language-wise homogeneous, which is unlikely to be the case unless, say, something catastrophic happens to Canada causing its population to flee to neighboring countries (and even then that's a bad example because Canada is heterogeneous itself).
