France and the UK are still top 10 immigrant sources in Canada (as is the US, for that matter). And while Canadian immigration policy obviously has no bearing on that of the US, it's clear that there also are still large numbers of Europeans interested in coming to North America. Moving "up" to from a developing country to a first world country isn't necessarily the only pattern of immigration - as evidenced by the millions of Canadian and American emigrants around the world.
