We took the Lynx bus to SW several years ago. It was really prettyb easy. Go to the TTC, look for the bus with the 'paw prints' on it. If you go to the Lynx website you can see the times they leave from the TTC. Or just go to the TTC a day or so before you go to SW and grab a schedule there. When we were there, the bus was about 3rd in the line along the sidewalk. It was $1.25 each way (it may have gone up a bit), be sure to have the exact change. Now.....be sure to tell the bus driver, when you board the bus, that you want to go to SW, the main entrance. We didn't do that and ended up walking back to it...took about 20 minutes. Completely our fault since we thought someone else had told the driver to stop. The bus driver will stop at a bus stop that is right at the SW parking lot, get off the bus and cross the lot, whick takes you to the entrance. When you want to go home, you just reverse all that, but you will have to cross the street. Not a problem. Look for the bus stop sign with the paw print on it...about 30' down the road, to your left (if you have crossed in the crosswalk) if memory serves me.
It took about 30 minutes each way...very easy. A lot of the passengers on the bus were CMs.
