Harper's government added more debt than any government in  Canadian history, routinely running deficits of over  20 billion per year and even over 55 billion on occasion. . This after 9 years of surpluses under Chretien /Martin.

Harper was never really fitted to be PM, the only work he had ever done except as a mail room clerk  was as a lobbyist. He was nothing but a lobbyist for various well heeled groups when  in power .He did not understand governance and was not suited for it..

Harper brought the economy to a near stand still and it is only now recuperating from his ham handed  and highly  ideological rule.
