As
I've described before, I too have wondered about VIA
temporarily leaving the north mainline until it is upgraded to the point that they can provide half-decent intercity service.
Here's an edit of the October 2021 GO timetable which replaces VIA west of Kitchener. I added a Stratford-Toronto commuter trip like
VIA wanted to do in 2016, because the Stratford-Kitchener segment is slightly less dilapidated than the London-Stratford segment.
Table only shows trips continuing west of Georgetown.

This change depends on CN permitting VIA to reroute the Sarnia service via Brantford. If necessary, we could mitigate the impacts on CN by building an additional platform at Woodstock station. Although the CN Dundas Subdivision is fully double-tracked, the stations along it only have platforms on the south track. So in order to meet trains in the opposite direction, VIA trains need to weave back and forth across the two tracks between stations. A second platform at Woodstock would allow VIA to schedule meets there, enabling ordinary double-track operations from London to Brantford (or Ingersoll to Brantford if meeting trains both stop at Ingersoll).

Brantford would have been a more obvious location for upgrades, but it looks a platform there would be a lot more expensive due to space constraints. Woodstock actually has enough space to add dedicated VIA sidings, which would allow the platforms to be raised for level boarding.
By the time the new platform is built, there would already be hourly AD2W GO service to Kitchener, providing far more scheduling options for GO trips to London than the conceptual timetable I made. There's a good chance my timetable is impossible anyway due to freight movements which I don't know about.
