I am "first generation Canadian", my parents having been children when they immigrated to Canada.  I'd always thought that "diversity" was a big positive in that it brought a plethora of new ideas to the country, new ways of looking at things.  However, having read this article, and given it some thought, I agree with its author.  My parents embraced all things Canadian and insisted that I not learn their native language (THAT was a mistake!) .  They didn't tolerate their immigrant parents fond remembrances of the life they left (few but fond) and were harsh with them.  Their ethnicity was apparent primarily in their food choices and little else.  Their attitude was that the family had come to Canada to leave behind certain negatives - not bring them to Canada with them.  While I think they might have enriched my life by holding onto more of the "old", I am grateful to have obtained a university education and married late in life - neither of which would have been possible otherwise.
