Chris Surely it is too late to raise a by-law once the 7 are already installed in the unit?
It may be too late for that unit but sooner or later the tenancy will change. Also, you don’t want your building to get a reputation for being a soft touch when it comes to over-crowding. If you think it might be an issue in the future, get it done now. Meanwhile, you could be talking to your local council about the overcrowding as they may have policies already in place.
