Trudeau's stimulus disbursements were delayed.  BoC crashing rates again after oil price drop in 2015 and lower bond yields drove the housing market.  Lower dollar helped exports.  And there's been pent up demand for business investment since the Great Recession.  Trudeau may have boosted some confidence but can't give him major credit for the expansion.  He just hasn't stood in the way of economic growth (yet, may change when small business hikes and carbon tax kick in).
