However , with the summer temperatures of 2009 having been the coldest since 1816 , the number of successful tobacco and food crops were fewer and more expensive because of fears of an early frost that never quite surfaced in 2009 . The same effect was felt months after the severe December 22 – 28 blizzard with the subsequent blizzards on February 5 – 6 , 2010 and on February 25 – 27 of that same year . There were two outbreaks of blizzards that occurred in this area between January 25 and February 2 , 2011 . After the start of 2012 , the effects of the March 2012 North American heat wave has rendered virtually all snowfall in this area non-existent for the first time since the winter of 1994-95 . The heat wave has also shattered all of the temperature records throughout the Ontario tobacco belt along with the rest of Southern Canada and parts of North America . This heat wave has extended itself into the summer months . During August 2012 , only parts of South America and Northern Australia experienced temperatures that were cooler than usual . The heat wave officially ended in early November 2012 when local temperatures plunged below
