Hydro is tough for a lot of reasons. It's pretty ecologically devastating, flooding large regions and turning fish into mulch. It can also produce as much climate impact as a fossil fuel plant - or more - largely due to methane and CO2 emissions from the newly flooded land. [1] I'm not 100% sure where the Quebec hydro mix actually lands due to the significant variability on a plant-by-plant basis, and I don't know if that's factored in or how it was amortized in the StatsCan link - this wholistic analysis is fairly new afaik.
I trust StatsCan though, so your point is well made.

Do you have a source hydro turbines “turning fish in to mulch”? I’ve been around lots of hydro projects and the main hazards for fish seemed to be either dewatering of habitat due to turbines reducing flows too quickly or I heard it is bad for them if the dam uses the spill way and makes the water all aerated
I was being a bit glib there, I just meant that it was bad for the fish. My understanding is the average mortality rate for fish passing through a dam is 1 in 5. [1]
