I don't get why you see indifference here. Or why you think a GO service that takes hours is really impactful (rather than a token effort). I think it's hard for organizations to focus everywhere. And given all that is going on with GO, UPE and Pearson airport itself, going west of Union is a major endeavour best left for its own phase.
If HFR pans out on the pledged timeline, GO's transformation should be well along and there will be more clarity on how to proceed. Hopefully, at that point, the replacement of UPE and a firmer concept of the Pearson Hub will have emerged.
While Toronto-Ottawa-Montreal Quebec is an overall transformative opportunity .... highway congestion west of the GTA is much closer to meltdown. East of the 115, Highways 7 and 401 are not at capacity, there is a choice of airlines offering frequent service, and (absent covid) there is a very respectable set of choices for train timings.
So, while HFR is a great commercial opportunity to compete and win modal share, better rail service west of Toronto is about capacity deficit that is being deferred for Phase II.
I can't fault the logic of starting with a Phase I and doing a Phase II later.... and I understand that a federal viewpoint will see the interprovincial connectivity as the place to start. And I'm not siding with Ottawa versus Queens' Park. Lots of bad ideas and poor execution, plenty of blame on all sides. But when politcal foibles and bureaucratic turf and mandates and federal-provincial demarcations and sensible management of project scopes are set aside, the data might show that there is more pain and less runway left by continuing to underfund capacity west of Toronto than east of it.
In bureaucracies and in politics, there is always a logical explanation for why things are being done the way they are and at the speed they are.... I'm just pushing that particular boulder up the hill.
