^ This is a very old argument that never dies, and rarely changes anyone's views, so I won't expect to change any views. However....
With respect to Hamilton - over the past few years, CN field staff who were asked about the progress of work repeatedly told onlookers "We are ready to go, as soon as Metrolinx signs the work order". If things took too long, or if certain platforms weren't ever included, don't be blaming CN.
I can't imagine any sane 1990-ish railroader looking at the Grimsby Sub and saying "We better just leave things exactly as they are now....GO Transit might want to run a service here some day, ya know". The message from Ottawa for the last thirty years was consistently, we don't have any interest in enhancing passenger service on that line. And the message from Queens Park was, we sure don't intend to pay for something like that. Frankly, the old Grimsby Sub was a pretty crappy railroad. So, in the absence of any credible and actionable interest by government, CN shrugged and said OK, we will configure the line to fit our needs, and we will extract unneeded or non-revenue-producing capitalisation. You snooze, you lose.
How is that being unsympathetic?
I do think that people who ask "hey, where did the ability to run passenger trains go?" or who wonder why redundant routes were torn up have their heads stuck, well, someplace. There has never been a government willing to address on a going-forward basis the issue of maintaining rail capacity against the day that it will be needed for passenger. Rail freight volumes have grown dramatically over the life of VIA and GO transit. Who says that the railways had an obligation to preserve the space for passenger, by not changing their technology, by investing capital that created no income... instead of looking to their existing assets, improving their asset utilisation, running trains much differently, and only investing capital when the existing assets weren't enough for actual business? Certainly not Parliament, and certainly not the regulator..... in fact, they said the opposite.
Railways do a lot of dumb things, sure..... but the country would not be well served by demanding that they maintain at their own expense capacity or capitalisation that might, maybe, be needed some day for passenger trains. That's government's job, and nobody of any political stripe has ever stepped up to the plate on that.
