Hey Brother,
I don't know where you're setting out from, but if you are around Union, there are a few Go trains a day that go straight to Bramalea station (35 minute ride). From there it's about twenty minutes on foot across Steeles, or you can hop a Bramptom bus (#11, I think. Show your Go ticket and it's only fifty cents) for a five minute ride. I don't have a car when I visit Toronto, so I always use the Go.
