From this PC election announcement for $160 million of upgrades for the London service, I think it’s safe to say it will be made permanent.That's great to hear! That's real progress almost a year in.
I hope GO makes this permanent and can move up the London AM departure time to a later time.
The big question is if the Kitchener Line gets re-named to the “London Line”. The PCs seem to like re-naming things, like Old Elm GO and the Hazel McCallion LRT.
