Sounds like somebody borrowed the term "Arctic Vortex" which was used to explain the unusually cold winter Canada and the US had two years ago (winter of 2013/14). This summer in southern Ontario it has been rather cool and wet for the most part although this weekend is supposed to be hot and humid (32 degrees C with a humidex of 40).
