I am virtually blown away by such a convoluted project that threatens life and limb of everyone and every living thing within a many mile radius. And when simple projects like battery storage, solar energy and wind power turbines are now very efficient and affordable at exponentially less cost. 
But the absolute nonsensical matter is that cost. TCE proposes to build this antique monstrosity for a whopping $7 - $10B and then I discovered that the ROI over 50 years is a miniscule $6.2B (ROI being return on investment). 
Math may not be my strongest suit as I'm only a lowly chemist by profession! Only using math daily to do calculations and formulas. But I really consider the ROI an insult to the people, taxpayers and ratepayers of Ontario and Canada. To stretch out the poor ROI to 50 years shows the short sightedness of those who are all fired up to shove this project down our throats. Whether we, the 800+ people being endangered by such a care-less project, matter to anyone spearheading such a massive mistake. 
This what Google AI had to say about the ROI:

Economic Benefit: Despite high upfront costs, the Canadian Centre for Economic Analysis projects the facility will contribute $6.2 billion to Ontario's GDP over a 50-year operational span and support over 1,700 construction jobs.

(My comment: only about a dozen jobs once completed)

Sincerely,
