To me "a bunch" is when it'd be tedious to list them. For a few years the UK had few enough that you could list their names, then gradually four, three, two, one, none. Canada as a whole isn't in that place yet, though it doesn't have plans to build more of these plants and they will gradually reach end of life or transition to burning something else.

Coal isn't one of the "convenient" fossil fuels where you might choose to run electrical generation off this fuel rather than figure out how to deliver electricity to a remote site, coal is bulky and annoying. Amundsen Scott (the permanent base at the South Pole, IMO definition of remote) runs on JP-8 (ie basically kerosene, jet fuel), some places use gasoline or LNG. I don't expect hold outs in terms of practicality for coal, it's just about political will.
