How did the High Park Toronto court dispute shape municipal pickleball noise policy?

In 2023–2024, residents adjacent to Toronto's High Park public courts organized legal petitions and independent acoustic engineering audits documenting constant 68+ dBA noise penetration into historic residential neighborhoods. The resulting High Park Sound Accord established a landmark precedent for Canadian urban park management: The city implemented strict operational curfews (play restricted between 8:00 AM and 8:00 PM), installed heavy perimeter noise curtains, and enacted a city-wide policy banning pickleball conversions within 100 meters (328 feet) of homes unless full acoustic containment is engineered.
