Bus

Assuming you don't want to pay for a cab, or do a one way rental or fly.

Oh, or have a friend collect you.
 
If you haven't booked tickets yet, you may want to consider traveling to London's airport (YXU).
 
Consider the taxi as your last option, I was on Canada on 2006 as a summer student and the taxi charged us 100 Canadian Dollars from the airport to hamilton ( a 35 minute trip)
