Paul Martin, the juggernaut that wasn't, is attacking his successor at 24 Sussex Drive.
Martin, who gained admiration across Canada and around the world for tackling Canada's deficit problem in the 1990s, now says the federal government should spend more and run deficits. Martin was finance minister in Jean Chretien's Liberal government from 1993 to 2002 but quit during an attempted coup to over throw Chretien and become prime minister himself.
Martin eventually did become prime minister, holding that office from December 2003 to February 2006 when he handed power over to Stephen Harper and his Conservatives.
In an interview with CBC Radio's The House, Martin called the Conservative economic plan, "an absolute disgrace."
Martin told host Evan Solomon that Finance Minister Joe Oliver should be opening the taps to run a stimulus program, just as the Bank of Canada has been doing by making borrowing cheaper with low interest rates.
"Fiscal policy and monetary policy have to work hand in hand, they cannot contradict each other," Martin said. "If the governor of the central bank is talking about the need for monetary stimulus, he also understands there has to be changes made in the [fiscal policy] and those changes have to be investments."
Martin called for more federal spending in areas such as education - a provincial responsibility - and municipal infrastructure. The Harper government points to the $53 billion New Building Canada Plan as proof they are investing in the future.
