Sheppard West, Line 2 to Sherway, and Ontario Line to Sheppard / Finch are the low hanging fruit, especially from a PC government which loves subways.
Further out you may see projects like Milton AD2W GO service, Hurontario LRT to Brampton, GO RER expansion to Hamilton, etc.
Really the Waterfront East LRT desperately needs funding as well, but Ford is well known for an aversion to streetcars so who knows if that will happen. Even if that manages to pull funding, I highly doubt Ford will back Waterfront West or Eglinton East.
