The province needs to fund higher, alternative GO service in order to ratchet back on the gridlock.
LSW needs to go to 15 minute all-day service every day, and they need to squeeze in another couple of peak period trains too.
Milton needs to be maxed out based on current infra. which would be about 3 more trains each way, and K-W needs to be pushed to its limits, particularly in the Union-Bramalea segment.

To tackle the central/eastern segments, they likewise need to get to 15 minute service, all-day, every day on the LSE and bring back express services......
Which yes, again, I'm going to point out the mess here was caused by failing to insist on burying the Ontario Line through Leslieville.
Likewise, they need to get Stouffville off-peak up to 30M 2-way, all-day.
You can't just accelerate work when that work is still going to be measured in terms of six or more years total. You need alternatives.
