...the streetcar. Sometimes I use the bus or the subway train, but I love the streetcar. I usually take 2 streetcars to get to work, and to get home during the week. I get a monthly TTC Metropass sent to me and it is good for buses, trains and streetcars.
However once the warmer weather appears I like to ride my bike. It is a great way for me to get exercise, and it costs little to run and maintain. The annual tune up and a can of oil is really all you need.
