The city has much less say regarding GO. It's nearly entirely up to the Province.
Convincing a majority of MPPs for any further changes to GO is a significantly more politically challenging task.
The city does however have a big say in a potential downtown congestion pricing system. And it's much easier to convince a majority of city councillors.
So I'd rather keep the discussion separate for practical reasons as there's very little point in combing two different things that have a huge gap in their political difficulty and are under different authorities.
Actually for practical reasons, congestion pricing and transit quality are very related. If the former is put in place while the latter is not improved, then angry commuters will bombard their MPPs with complains, and the provincial government will overwrite the city and strike down the congestion pricing.
GO is the major component here, but some improvements will come from expanded TTC services. We are getting multiple expansions in the outer 416, that should reduce the need for downtown car trips:
- TYSSE: already running
- Finch West: in a year or so
- ECLRT: in a year or so
- SSE, Yonge North, Ontario Line, Eglinton West: all in 8-10 years
So, things are not looking too bad.
