How can i get to Toronto airport from Scarborough?i live nearby 401&kennedy.?

If you live in Kennedy Rd and take 401 exit go west along the collector lane, then follow the sign of airport for about fifty minutes but don't go to airport road prior to the Pearson Airport. Yip

Do you mean Pearson or Billy Bishop? And you didn't say if you are driving or taking transit, or what time you need to be there. Giving specific information results in a more specific answer. And of course you can always take a taxi and let the driver worry about how to get there.
