Again, your relative is in a "seniors' residence", not a nursing home. There is a big difference. 

You can't just move into a nursing home. It requires that a doctor signs off stating that you are eligible. Then you fill out a form stating (in order) the nursing home you want to move into. Usually you can list 5, but you don't have to. The best nursing homes, at least in Toronto, often have 4 - 5 year waitlists. It doesn't matter if you're in a flop house or a nice home, the rates are basically the same. 

You can choose to move into a seniors residence, which is similar to moving into an apartment that offers 3 meals/day, light housekeeping and activities. Seniors residences aren't required to have medical staff, although some do. You are required to pay for extra care and it can really add up.
