...city’s first investigation under Ontario’s Environmental Bill of Rights related to unreasonable and excessive noise.”
A kid practicing hoops for 30 minutes is not unreasonable nor excessive.
Did she not notice the hoop and how close she would be to it before deciding to rent the unit? I mean it's not like they put the hoop up AFTER she moved in just to piss her off.
If I was the worker in charge of this case, I'd tell the woman to piss off and send her a bill for the time wasted.
