Forget the politics

So you canarob, TOareafan, CC are complaning that Brampton does not get more train service when there is onl 4 million riders with the most recent statistics? 25 million people road the Lakeshore, including Hamilton which is the same size as Brampton and gets the same service. I am sure Guelph-Toronto will become an all day route at some point (not Kitchener, 2 hours is too far for more then 3 trains per day.) But GO is expanding where the riders are. You should encourage more people to fill the Kitchener lines. Milton, however, is the busiest line not near lake ontario, but that is on CP.
The Lakeshore lines grew at the slowest rate of all lines from 2001-2010 (sorry, I couldn't get comparable 2011 data), so I don't think demand is the issue.
