Toronto Fire responded to a massive surge of nearly 1,500 calls for service within a single 24-hour period. As reported by the source, Toronto Fire Chief Jim Jessop noted that this volume represents the second-highest single-day call load the service has ever experienced, trailing only the historic 2013 ice storm.
