As an Ontarian, I love CANDU.
As an Ontarian, the thought of spending $500B on a couple of reactors makes me furious. Ontario is not going to become competitive again with the most expensive electricity in the world.

Until a few years ago it was cheaper than methane/natural gas:

At least when it comes to refurbishment, the independent (reports to provincial parliament) FAO found:
> Overall, despite near-term Nuclear Price increases, the Plan is projected to provide ratepayers with a long-term supply of relatively low-cost, low emissions electricity.

Their projections go to 2064.
New-nuclear is worthy of discussion, but given we have stood up supply chains via the refurbishment process, there's a lot of knowledge out there. My current largest complaint with the new-nuclear plans is the SMRs.
I did find this (potential?) $100B number on Ontario nuclear energy:

but if you take that number and 'ammortize' it over the average 40-year life span of reactors, it comes to $2.5B/year (in capex), which is about ~1% of the provincial budget. I'm not sure how much raw GW capacity that would add, or how many GWh would be generated annually, to do the math on the per-kWh (capex?) cost.
The article goes over the pros and cons of various points in the energy mix debate.
