TTC (The Toronto Transit Commission) is an absolute monopoly on public transport the city.
TTS includes metro, buses and trams. All of them are tied to a single system of payment and transit. Made a single payment, you can travel arbitrarily in one direction with transfers between any transport included in this system. Ask the driver to give you a follow-TRANSFER for these purposes. Sometimes interchange points are tied together, and you have to pass from one transport to another.
Important: fare with cash payment above. You should have enough money without putting as you drop money into machine, which does not give change.
