Where does Toronto get the majority of it's electricity? I don't mean geographically, but I mean what type of fuel? Nuclear? Coal? Gas?
Does it all come from Pickering Nuclear pretty much?
It's all on a grid, so hard to say exactly where it comes from.
However, the realtime, hour-by-hour, source for Ontario's electricy is on the front page of the website of the Independent Electricity System Operator

From 5 pm to 6 pm today it was:
Nuclear: 10,046 MW
Hydro: 5,477 MW
Gas: 2,620 MW
Coal: 258 MW
Wind: 1,217 MW
Other: 163 MW
If you look at the
consumption during the last week or so, the lowest hour is about 12,000 MW. So nuclear can't be much higher than that (because you can't create more electricity than you are using for long, or you have a big problem, and you can't turn down a nuclear reactor much). Also the daytime peak recently is about 22,000 MW. So at the peak, nuclear can only be 50% or so of your electricity.
The total capacity of the 6 reactors at Pickering is only 3,000 MW. It's likely much comes from Darlington which has a capacity of about 3,500 MW. The 6 active reactors at Bruce are almost 4,700 MW, and it will be over 6,000 MW if they get all 8 running at the same time.
