I would not be surprised if Hamilton goes to the Liberals this election, with Horvath losing her seat. Not mentioned in the list above, but I read that they would expand GO to Brantford and improve Niagara services. These connections could make Hamilton a major hub in the region. Add in the LRT they're getting, and we have a city which could give Toronto a run for its money.
I'll also add that it is interesting that they are (re)committing behind the Scarborough subway, especially since Chow wants to see it move back towards an LRT. While I can see the pros and cons of each option, I would think that they would phrase it more generally, like, "Improved transit for Scarborough," or something like that.
