Anybody who pretends that the immigration of old is exactly the same as the "new" is wrong to do so, Doc.  No arguments.  

Proportionally, against our present population, Canada accepts fewer full-time immigrants than in many periods of the past.  1911: accepted 400,000.  Just few years before, over a million in a five year stretch.  The 1911 number represented about 5.5% of our 7 million people.  Today, 350,000 immigrants represent about 1%.  Of THAT number, likely 10% is Muslim.  I just can't get worked up about it.  Okay, let's do what some posters do: dump another 300,000 "part-timers" in with that 350,000--the 10 year visa folks who must live here just half a year annually.  Still less than 2% additional population.  

More to come...
