Sigh.
I have said it before, and I'll probably have to say it again:
The heavy costs in any transit (or transportation) corridor are those with respect to establishing the RoW in the first place. That includes everything from acquisition to surveying through utility relocations to cutting and filling, building bridges, putting in any services (sewers, electrics) establishing the roadbed itself and finally laying down the running surface. Unless you're in unusual circumstances, the last - the running surface - is amongst the least expensive items.
So, if you've got two corridors that roughly serve the same area/purpose, one which is already a busway and the other that exists solely as a conceptual line on a map, then the quickest and cheapest way to get LRT is to convert the busway that already exists. If the overriding goal is LRT as soon as possible for as little as possible, that is your best option under the circumstances.
With respect to LRT corridors in the east end of the City, the choice of which corridor to make use of depends a lot on the goals one is trying to achieve and when and also what else is being contemplated. If the goal is to go further east than the edge of the Greenbelt, we also have to consider the costs of establishing LRT in the new corridors beyond the Greenbelt as well.
As it happens, I did some estimation calculations on the relative cost of Hospital+Cumberland as LRT vs East Transitway conversion + extension to Orleans last year because I was curious as to which would actually come out as the cheaper option - I truly did not know and you can indeed find posts on here by me in which I have argued for Cumberland+Hospital as LRT first before converting the East Transitway (this was under the premise of doing both, which adds a further wrinkle to the question because then it's a question of what order to do them in and not which is cheapest/quickest). The East Transitway conversion and extension does comes out slightly ahead because of the relatively low cost of conversion of the East Transitway. However, and this is kind of interesting, the new segments in Orleans in the two corridors have vastly differing costs. The 174 corridor is a lot more expensive than the Cumberland corridor because of all the interchange bridgework that is required, so much so that the total costs of East Transitway conversion + extension to Trim as LRT vs Hospital-Cumberland as LRT came to within $10M.
Another element in the question of which corridor to use in the current circumstances - East Transitway conversion and extension or Hospital-Cumberland as new LRT - depends on what other expenditures are contemplated at the same time. That is, are we committing to busway expenditures that can be avoided? It may seem pedantic, but it is an issue nonetheless. Is it convert the East Transitway to LRT vs build a new LRT line in the Hospital corridor? OR, is it convert the East Transitway AND build BRT in the Hospital corridor vs build LRT in the Hospital corridor and leave the East Transitway as it is?
As it happens, the Hospital corridor is not on the funding request list but the Blair to Navan and Navan to Millennium portions of the Cumberland corridor are while converting the East Transitway as far as Blair is on the list but extending it further (in any form) is not. Great combinations, aren't they? There's no request for funding a new busway in the Hospital corridor, so arguing for a switch of LRT from the East Transitway to the Hospital corridor is more difficult because of the costs of establishing a new RoW. And since there's also no extension of busway on the 174 corridor either arguing for a shifting funding around of funds for BRT on one corridor to pay for LRT in the other is impossible. A cynical person, say one more so than I, might say this was done to make the case for extending LRT to Orleans on either corridor a lot more difficult by giving no easy options for moving money around.
