Canadian owe Harper a sincere "thank-you" for GST reduction from 7% to 5%, and also his attitude towards spending Canadians' tax dollars (he cuts lots of federal spending by laying off lots of federal employees and reformed their golden pension plan etc), also Harper was never willing to accept more refuges.
I guess matured middle-class people (esp. those older than 40+) will understand how naïve and immature Justin Trudeau is.
