Replying to New Torontonian

In one week, I will be a hogtown local. A few questions for you peeps.

Which are the closest hills to downtown/UofT area? I think I'll be living here as I am working down in the baystreet area (dolla dolla bill y'all). Which hills can I get to using a bus of some sort? I don't want to bother with anything that's complete garbage. Are my only two good options Moonstone and Blue? There will be no night riding for me due to crazy hours at work.

Is there a bus I can pay for to get me to Collingwood/Blue? I know there's one to Moonstone.
