Tornadoes in Toronto

Did you know that Toronto is subject to tornadoes? Until just this past month, I didn't! Yet while tornadoes are quite rare there, the geography, meteorology, and climate do support them. (Google search on "Toronto" & "tornado")

Off the top of my head, and not counting the occasional Wizard of Oz parody or crossover, I can't recall any FK fanfiction featuring a tornado or tornado warning!
