The McGregor Music Festival is the latest event cancelled due to the COVID-19 pandemic.
The festival had been rescheduled to September 20, but organizers say there's too much uncertainty to commit to that date and the event will be cancelled altogether.
The 31st edition of the festival will now take place June 13, 2021.
Over the past 30 years, the event has raised more than $350,000 for the Windsor Cancer Centre Foundation's Patient Assistance Fund — money has also been used to purchase equipment for the cancer program.
