Nuke power is the cheapest and cleanest energy alternative for British Columbia, Alberta and Washington state - less than the cost of new gas plant or operating old fossil plant, and far less costly than massively environmental destructive hydro.

That stated,  BC has enough power  into the 2030's, with massive wind surplus and new nuclear coming from Wa state, the next Alberta government already ratifying nukes as its preferred fossil alternative,  and massive surplus's of contracted IPP power available. BC Hydro is already spilling water over its dams to meet  IPP contract commitments.

It is likely a new NDP government will renegotiate the lucrative IPP contracts under proceeds of crime legislation,  but I would expect the IPP surplus will remain.

With Columbia grid surpluses and 2 cents a kwh costs projected to last into 2030, there is no way Site C can break even. 

Better the money be spent building 200K rental housing units that would at least cover costs at sub $500 rents.
