At 12:01 a.m. on May 16, 2020, Ontario is lifting the Restricted Fire Zone (RFZ) designation that was put in place last month across Ontario's fire region. The province will continue to assess forest fire hazard conditions and an RFZ designation may be reinstated in higher risk areas if conditions deteriorate. These restrictions are put in place in order to reduce the number of preventable human-caused fires and lower the risk of wildfires impacting the public.
