Not going to comment on how your family planned to handle this.
But for qualified hotels, I think their staffs will try to avoid interacting with you/person in quaratine in-person as much as they can.
There are protocol and procedures.
Travellers are the ones that needs quaratine. No one is "germs free" in reality. But this is a move to try to slow down spreading of the virus in Canada.
Here is some lighter reading on this family trying to stay isolated with their kid that got covid within the same apartment.
They tried to stay sepreated, clean, wear mask...etc. But it's not very practical.
