There Is No Right To Party (Waterloo (City) v. Persons Unknown)

Social media, among other things, allows people to organize "pop up" events that can result in the gathering of large crowds. Although these events can be positive for attendees and valuable to a business or charity, certain "pop up" events, like street parties, have become a target for municipalities because of their potential to negatively impact local neighbourhoods and result in property damage, road blockages and public safety risks.

To prevent the holding of large unsanctioned events, municipalities have enacted "Nuisance Party" by-laws and engaged the courts to obtain injunctive relief whenever they become aware that large-scale unsanctioned street parties are being organized.
