IN AN EXAMPLE OF QUICK THINKING AND APPROPRIATE ACTION, A MAN IN THE SHED AT THE TIME THE TORNADO STRUCK IMMEDIATELY TOOK SHELTER UNDER A HEAVY WORKBENCH AND AVOIDED SERIOUS INJURY AS AS RESULT. DEBRIS FROM A BARN ORIGINALLY AT THE WESTERN END OF THE DAMAGE TRACK WAS CARRIED OVER 4 KILOMETRES. NUMEROUS TREES IN THE AREA WERE UPROOTED OR SEVERELY DAMAGED AND A NUMBER OF LARGE BRANCHES WERE DRIVEN INTO THE GROUND BY THE FORCE OF THE TORNADO.

THIS IS THE 9TH TORNADO OF THE SEASON IN ONTARIO. ONTARIO NORMALLY HAS 13 TORNADOES EACH YEAR IN A SEASON THAT RUNS FROM LATE APRIL UNTIL EARLY OCTOBER.
