Buses actually suck. And I am from bus-ville here. I used to take a bus as a “last mile” solution. Fine. It is tragic that we have people bussing long distances on Steeles, Dufferin, Lawrence, Sheppard and Eglinton. Eg and Finch are a good start, but the situation is overall tragic for quality of life in the city. So many people spending so much time going nowhere. We are literally burning human capital.I think you are overestimating how frequent and rapid the LRT would be, and underestimating how fast and effective a bus on the route is. I don't think the benefits of LRT are enough to make it worth that extra 5-15 minute walk. (Plus there is the accessibility concern, some people can't walk that extra 5-15 minutes)
Buses work pretty well overall presently. A bus on Royal York takes me to my destination and is fairly frequent so shows up when I need it to, which is all that I require as a transit user.
This isn't to discourage building LRTs, just that I think LRTs shouldn't come with the context of seeing lower levels of service or ignoring potential for service improvements on adjacent bus routes.
