The Milton line is the CP mainline through Toronto, so a very daunting problem to solve. GO has been able to purchase most of the rail corridor it runs over, with a very clear standout exception of the Milton line due to it being CP's crown jewel.Essentially, you have two options: 1) Find some space to build around CP on the same corridor, or 2) Find some space for CP to relocate to a new corridor. Both are daunting challenges, and it will take a lot of money and negotiations to see either of them through. I understand Metrolinx's hesitation, even if it is a major ridership corridor, there's just lower hanging fruit in the face of those options.
This is one of the reasons I thought that a proposed new Eglinton GO corridor *might* make sense -- one that goes to Airport Corporate (phase 1 'SmartTrack' section), then Mississauga Square One (phase 2), and then connects to the Milton line at Erindale (phase 3). But a brand new GO corridor would be incredibly expensive, as that will have to be mostly underground.
