Well we have to look back at those projects and see how they failed, or were stopped. The previous Liberal era was plagued by provincial level politicians sitting on projects for years and years and not being able to make up their mind on what they wanted to do. Miller proposes Transit City, not much progress is done and Ford gets elected with his war on car message (and in many ways his arguments were absolutely valid), then Dalton sided with him and cancelled Transit City, then after Toronto failed to meat the funds, the liberals flip flopped again. What makes Ford different is he clearly has a strong priority of trying to cut through as much bureaucratic red tape as possible. Eglinton West and SSE will start boring next year, which is unprecedentedly fast in Toronto time, and there is a clear strong commitment from ford to try and get all of these projects through. The only chance that any of these projects will fail is if Ford somehow loses in 2022 (which is unlikely with current projections), and whoever replaces him pull a Mike Harris and fill all of the tunnels with cement, and will scrap OL for the DRL which would lead to a ton of outcry.
