I think it's important to have a substantial urgent care centre in the middle of the city, given the huge daytime population (and pretty substantial nighttime population) nearby -- many of whom are without cars, making transport to a hospital harder. But an actual real-deal hospital is so much more than something like the Chumir is or could reasonably be. Here's the Sheldon Chumir (with Central Memorial Park for reference) to scale next to the two smallest hospitals, the Rockyview and ACH, as well as the Holy Cross that started this discussion. (I included the U of C's Child Development Centre as well as the Ronald McDonald House near the ACH; they are sort of part of the hospital system there.)

And here's my rough and ready attempt to show floor plate sizes; hospitals are funky things.Note I didn't highlight parking structures. The Chumir is 8 stories; so are most of the tall parts of the Holy Cross. The ACH is 5 stories plus a very substantial (higher than one story) rooftop mechanical floor; the Rockyview is sprawling, but built on a sloping site and into the side of a hill; many parts are five stories.

A one-block site like the Chumir just has no way to accommodate that level of medical equipment. You can't build vertically much more because of the need for elevators; once you start having in-patient treatment, then you need patient rooms and those rooms need windows so you can't have a giant boxy structure. (The Rockyview gets a fair number of windows through terracing and it's still pretty dark inside.) And as a reminder, these are the small hospital sites. the Foothills is the size of the Rockyview and ACH campuses put together and it is really built up.
