Contrary to to your earlier assumption I actually live in the east end of Scarborough and I take the busses along this route all the time, I am very familiar with this route.
1. The only stop consolidation I might agree with is the Midland/Falmouth stop. Removing the Mason Rd stop. since the Markham Rd stop can't be moved, would result in a gap of 1160m, that's two far and there are several apartment buildings and many homes in the area at Mason. Both stops at Lawrence and KR/Morningside would be fairly well used. both from walk ins and bus transfers, and it's already long enough from Lawrence to Galloway. There is a High School at West Hill and many homes, and removing that stop would result in spacing of 1.6Km, really? The stop at Ellesmere is not in the UTSC campus. it's right across from a Centennial College campus. and there are many apartment buildings to the west that would be far from the UTSC stops.
2. The EA did not call for parallel bus service, and why would you want those using the West Hill stop to be in mixed traffic busses all the way to Kennedy to save nothing in travel time for the LRT?
3. As I've said, UTSC does not have three stops, and the location of the main stop is in a central location in the Campus, where you have previously shown where you want it is not,
As for your grade separations, the one at Eglinton/KR is not needed at all, the LRT would only cross westbound traffic on KR that has not turned on to Eglinton, signal priority would be a non issue here. Why Guildwood GO? The intersection at Celeste is minor, signal priority is also a non issue here. The LRT at Lawrence would follow the predominant direction of traffic. The EA called for half the trains to be short turned at Morningside. so decent signal priority would also be doable. The West Hill triangle would require a 500m long underground section with an underground station, not cheap.The EA already called for a separate bridge across Morningside Park, on the east side of Moriningside, meaning the LRT would be using a side of the road alignment from West Hill to UTSC already. A much higher and longer bridge would be required to go directly from West Hill to the UTSC campus, much higher cost for negligible benefit. And why on earth do you want a new bridge across the 401? There is nothing on Morningside here to get in the way.
You have substantially increased costs for little benefit, and made access harder for many, as well as requiring parallel bus service. And what else would have to be cut to pay for it? As well as you will cause further delays by needed to redo the EA.
