Charges are pending after the party broke step three rules.
With Ontario currently in step three of the reopening plan, multiple gathering rules are still in place across the province.
According to Dufferin OPP, a massive gathering of over 1,500 people was broken up near Orangeville over the weekend after police received several noise complaints and reports of a large crowd.
"Police attended the location and observed approximately 1,000 cars parked in the fields of the property, loud music, spot lights, and an estimated 1,500 people in attendance," an excerpt from the report reads.
The situation was so large in scale that Rapid Deployment Officers from several OPP detachments were called in to help disperse the crowd and traffic control the vehicles leaving the premises.
The organizer of the event is now facing pending charges under the Reopening Ontario Act.
According to Ontario's reopening plan, outdoor gatherings can only include up to 100 people, while indoor gatherings are maxed at 25 people.
