The economy is unlikely to remain white hot for the next two years, and a slowdown or even recession is possible within Trudeau's first term.  He won't likely be blamed for it any more than he is given credit for the current strength.  But running a near $30 Billion deficit when the economy is peaking is foolhardy.  Walking into the 2019 campaign with either a $50B+ deficit or more tax hikes is hardly an option, yet Trudeau may paint himself into a corner with no other levers during the next inevitable slowdown. And he will be punished for it.
