In Toronto regulations were put in place required coordinating with Police, Fire, Ambulance, and submitting applications to use ANY private space for an intended "rave party".

The spontaneity of gathering your friends to dance on the beach, use a private warehouse after hours, or host a house party that went past 2AM, was now risking police showing up and handing out fines.

Regulation is the fastest way to kill anything unique and valuable.

[EDIT: Found a report for City Council recommendations related to this. It's a dull read, but historically facinating if you were around back then. https://www.toronto.ca/legdocs/2000/agendas/council/cc/cc000... ]
