Stopping work on the Site C dam would be stupid.  

Costs to remediate the construction site are missing from the UBC analysis.  The inflated costs to build it 20 years later are missing - are they greater than the 20 year cumulative losses?  Alberta is phasing out coal fired generation . . . is that considered?  

The authors say electricity could be purchased for less by buying from America's Columbia dams.  Do we want to be dependent on electricity from a country governed by the orange buffoon; a president who declares that all other interests come second to "America First"?  We are supposed to be switching to electric cars in the coming decade . . . where will that power come from?  Vancouver wants to phase natural gas out within the city.  What will replace that?   Electricity of course.

This is an electrical generation project that will produce for approximately 100 years.  To look at short term horizons to justify shutting it down is foolish - purely political not practical.
