I'm not saying they're the same.
I'm saying they're part of the same system, being funded by the same taxpayers.
You're dismissing a minimum 15% reduction in capacity as 'no big deal', when in reality it's a very big deal.
We're burying/overbuilding the Eglinton West LRT and SSE at great expense, and value engineering a critical line that that demands the absolute most capacity. The Eglinton West extension and SSE both run through areas that Ford and the Conservatives benefit from politically.
It's all a perfect example of everything wrong with transit planning in Toronto.
The Ontario Gov (seemingly at least) is not playing a zero-sum game with the 4 priority lines they are pushing. They are pushing all 4 forward at a reasonable pace (pandemic included). They have improved the SSE (more stations, longer, finally reaches Shepherd ), the EWLRT (complete grade separation, protection for the future capacity to the airport employment area), and the Ontario Line ( longer phase 1, more stations in phase 1, shallower stations, ability to be run close to GO Trains, ground level and elevated in some sections to save costs).
As a transit enthusiast, I can't complain about getting more grade-separated transit. Decreasing the capacity of one line by 15 percent but having it built sooner and faster is not a bad trade-off.
I agree that 15% (about 4500 PPDPH) is a significant amount. But starting an Ontario Line system in Toronto makes adding more lines easier in the future. As I keep repeating, look at Vancouver. They have built so much transit in such a short amount of time because they use smaller trains/stations. They even have stations fully funded by developers because they can build them so cheaply. ($40 million for elevated, under $100 million for underground) The Skytrain system is lower capacity than what Toronto needs, but there is a middle ground here. We don't need to build huge stations like the Spadina Extension when we can built more reasonably sized stations faster.
