There was a similar "white flight" from the eastern suburbs of Toronto, following the 1970's, as mostly Asian and some Caribbean immigrants moved into Scarboro (a very extended suburban area) and the middle-class whites who had originally formed those suburbs moved north to smaller centers, most notably to the city of Barrie, Ontario. Barrie has experienced the most rapid growth of any urban center in Canada in the past few decades. In '85 it had about 50,000 people. Now I believe it's over 125,000 and still growing.
