I do recall that the topic was beaten to death before deciding to be underground
My take: it is indeed big dollars to put it underground. On the other hand, this will be infrastructure we will use for the next 75-100 years to connect across this sprawling city - maybe we should build it for the long haul?

I’m the other way. Build the infrastructure “good enough”. More people get access earlier and success encourages future investment.
Calgary has 60k of track Edmonton has 38. Would you trade 20-30% of the system for underground downtown? I wouldn’t.
