If one looks at Edmonton, the LRT tunnel downtown is performing well even though one might argue that it delayed additional development which is now on course to have the same mileage as Calgary in a few years.
Bus tunnels will be more expensive than LRT tunnels due to more expense in handling diesel exhaust, increased fire hazards to passengers and having to build the tunnel wider if you want buses being able to bypass other buses loading.
Let's do it once and do it right! No starter line is going to be absolutely perfect and please everybody. The main thing about the tunnel is it serves the primary shopping, entertainment, business and government offices downtown with weatherproof stations which will lead to greater system reliability and passenger comfort.

While Calgary will eventually build a downtown tunnel, there is no firm plan for when this will occur. Even then, there will be no consideration for ripping up their surface line. Basically, a subway will only be built when the surface route is exhausted, a last resort. This is totally different than Ottawa's plan which calls for the ripping up of the surface route and very little build out of track to the suburbs.
Regarding Edmonton, after a generation of stagnation they are finally moving forward with LRT expansion. Their plans will exceed the capacity and suitablity of the current tunnel so a new downtown circulator line will be built ....................... on the surface and this will bring a number of new lines from the suburbs into downtown. Edmonton realizes that a fast expansion of LRT is not compatible with funding downtown tunnels. They also realize that the existing tunnel can only handle two interlined routes, while still providing the level of service expected for trunk transit routes.
There is a major problem with the economics of tunnels in mid-sized cities. The tax base is not large enough.
So we have a choice, build a tunnel and likely we won't be able finance much more for a long time, or build a lot of surface track between downtown and the suburbs. We have a choice. A mid-sized city cannot easily finance both.
Vancouver was able to do it because they have twice the tax base of Ottawa, Calgary and Edmonton, and because they were hosting world class events, when two of the three lines were built. The third line did not require any downtown tunneling.
