Toronto Snowstorms - Fri, January 2 @ 00:00 (-4d, 0h, 40m)
A series of blizzards whallopped Toronto with nearly a metre of snow, starting on this day in 1999. Mayor Mel Lastman famously called out the Army to assist, as people ran out of places to put all of the snow.
   
Great Ice Storm of 1998 - Sun, January 4 @ 00:00 (-6d, 0h, 40m)
On this day, in 1998, a days-long period of freezing rain hit Eastern Ontario, southern Quebec, New Brunswick and Nova Scotia. Power lines were torn down, transmission and radio towers toppled. In response, Canada saw its largest military deployment since the Korean War, and a massive reconstruction effort was launched to rebuild the grid. Many grateful Ontarians will remember the convoy of Con Edison vehicles from Michigan, coming to help. In the end, up to 5% of the forest cover was lost in the storm, and there were billions of dollars in damage.
