It's a quiet day so I'll defuse Casandra's lies:

1)  Harper gov't faced negative GDP growth of -2.5% during the worst financial downturn since the 1930's.   Massive deficits from the G20 were committed  in order to flood the world's credit system with liquidity. Harper committed to get to balance by 2015 and he did.
2) During the Chretien years federal debt-to GDP, a favorite metric of Trudeau and Morneau, reached a high of 63.5% in 1997.  Under Harper debt-to-GDP fell back to the low 30% range, rising to the high 30% range after the 2009 crisis.  By 2015 it had dropped to just over 30% again.    https://en.wikipedia.org/wiki/Canadian_public_debt#History
3) Under Chretien's reign oil+gas was about 14% of the Canadian economy falling to about 10.5% when Harper took office. By 2015  O+G was about 9% of the Canadian economy. 
4) cutting the GST was pale compared the failed Chretien promise to ELIMINATE it. 

put up more nonsense, Casandra, please :)
