The availability today of media from "the old country" is a huge difference in the integration environment between yesterday's immigrants and now.

Between the early fifties and the arrival of cable and satellite tv and the Internet, immigrants we basically cut off from their old culture, and had no choice but to watch local, English or French language TV and movies. They and especially their children would quickly get acculturated. Now, unless the parents make an effort to watch local TV, they can pretty much continue living in their old culture with little exposure to the local one. I see it happen, with kids born here getting to school with no language skills and little awareness of western, let alone Canadian cultural knowledge, which puts them at a huge disadvantage.

Adults may never become fluent in English, but they can acquire a basic  understanding of the language.
