How many WiFi access points can co-exist in the same space?

Local cable internet company wants to blanket my condo tower with WiFi APs to provide universal WiFi access for their subscribers. Will this degrade reception or throughput for existing private WiFi networks belonging to residents?

I am on the strata council for my residential condo tower. It is a 25-storey building built with modern steel & concrete methods, about 8 suites per floor ranging from 700 to 1000 sq ft in size. This being downtown Vancouver, pretty much every resident already has their own WiFi AP. In the vicinity of my suite alone, I can see over a dozen different SSIDs.
We have been presented with a request from Shaw Cable (one of three or four major providers in my area) to install WiFi access points throughout the building. Access is for subscribers only. Should we (the strata council) let them?
My concern is that residents with their own WiFi APs will suffer from degraded reception / throughput. Aren’t there are a finite number of channels or frequencies? Is there a threshold of density of APs that shouldn’t be exceeded? Do modern APs intelligently co-exist with each other, switching channels automatically? Can they share channels?
