The story missed the obvious- Trudeau is in deep and drowning in his cross-Canada and global PR caravan. He made promises he can't keep and he can't make good in two years. 

The Liberals will lose everything they've got in the West except Van, but Jagmeet will grab a big part of the left wing vote, they'll get pummeled in small & family business driven Northern Ontario, and the last election tee-ed up the Bloc Quebecois for a big comeback. With the cancellation of EnergyEast, NB is gone and the rest of the Maritimes are wide open because of the loss of the obvious economic spin-offs.

Even right now, he's basically down to being the Prime Minister of financial asset-inflated, de-industrialized, public sector Grand Duchy of Toronto & Ottawa. Nafta is almost cancelled, the US is back to energy self sufficiency, and in many ways, in a surplus position.

Scheer will bide his time and enjoy the bad acting. His party will cancel the glorified daytime liberal talk show now running Canada.
