Any person or corporation can buy all the units in a condo corporation that they desire. If they can get ownership of enough units, they can apply to the courts to terminate the corporation. When that happens, everyone gets their %age of the total sale price, whether low or high.
This is happening in Florida and may start happening here in Ontario. See:

That is a danger to the older condos that did not maintain the property (low fees) and the city has a number of expensive work orders. The unit values crash, CHMC will not insure the mortgages and the owners cannot afford the special assessments needed to fix the property. A developer then moves in to grab the land and rebuild, newer, higher towers.
