I would say precisely that. Yes, these things need to be subject to substantial scrutiny to see if they make sense, both in economic terms and in environmental terms.
The problem here is that this project was conceptualized at a different stage in the evolution of Ontario's electricity system. At that point, we were suffering from a condition called surplus baseload generation, which basically meant that the electricity demand went below the minimum amount put out from the system, principally from the nuclear plants, because you can't turn them down. In those circumstances, Ontario was having to export electricity at a negative price. We were literally paying other people to take it off our hands.
In my view, that problem no longer exists, because we have the entire nuclear fleet in various stages of being refurbished, with units coming off-line. What is very clearly happening, and projected to continue happening through the 2030s, is that the marginal fuel in Ontario is natural gas—fossil gas—so there won't be any surpluses. This is because whatever capacity we have is going to be needed to meet the demand in Ontario, and any surplus we generate would be from gas-fired generation.
