> Because we need baseload
This is 20th century thinking dictated by the inflexibility of thermal generation plants.
> reliable power
Nuclear is only as reliable as it's design, operations, and maintenence. Ask the French, they lost more nuclear energy output due to poor management than Germany did by phasing out the entirety of it's fleet.
And these are unproven reactors, you'll get to find out how reliable they are after operating them.
> Chinese dumping makes the uneducated believe it's cost-effective, but not in a geopolitical context that could conceivably involve our largest trading partner going to war with them
A) I would like to see some evidence of them actually "dumping" rather than having better economies of scale.
B) Last I checked, the solar panels don't need constant fueling by the Chinese, so the US starting a war with China has little to do with whether you should build them now.
> that isn't dependent on foreign goodwill
Ontario is choosing to build an unproven technology developed, owned, and fueled by its neighbor whose president keeps talking about annexation.
> this is the solution
This is a solution, and appears to be the only one your government considered. I'm willing to bet there was no actual study including non-nuclear options. Mind you, this is the same government that tore up all of your renewable contracts when they got into power, so they're more than a little biased.
Even if nuclear is the solution you want to go with, why go with unproven technology that is more expensive and isn't build, owned, controled, or fueled, by Candians?
> If you don't like that, feel free to continue investing in natural gas.
From what I can tell, Ontario's grid has been using increasing amounts of natural gas because of its heavy reliance on nuclear and its unwillingness to use renewables.
