There were about three decades of mass migration initiated by Canada.  Roughly, the last decade of the 19th century and the first two of the 20th century...to a record high of over 400,000 immigrants in 1913 alone--that certainly qualifies as "mass" when the population of the country was less than  8 million (1911 census: 7.2 million.)  Get this: in 1911, born-outside-Canada immigrants made up 22% of the population; 41% of people living in Manitoba, 50% in Saskatchewan, and 57% of those in Alberta and British Columbia. THAT is "mass migration."  Today, about 300,000 or so in a population of 36 million?  Microscope, please...

Most tolerant Canadians have eyes wide open, jenn.  

But curious about those "genuine concerns not being addressed."  Got a few of my own--most Canadians do.  What ones are you referring to?
