How to enjoy Toronto with just one subway ticket.

I made a discovery today while using the public transportation here in TO. Normally, to take a bus after leaving the subway, you need a transfer from the subway. It often has a time expiry, and it can only be used to transfer onto a bus. In other words, you can't return into the subway with that same piece of paper. That's why round-trips would require two tickets.

Here in Toronto, however, I discovered a gaping loophole. You can use these transfers to board the streetcars outside. And, if you take these to the end, they enter right back into the subway system. Then, you could get another transfer and keep on leaving and entering the subway! So, with a very strategic itinerary (and a shameless disregard for the rules) you theoretically could tour downtown Toronto for the whole day on just $2.75!

I made another discovery just now: I realize I have way too much free time...
