We get them all the time every summer in Saskatchewan. Of course, the nation's media live in Ontario, so it gets mostly ignored. Happens once in Ottawa, all of a sudden it's a national crisis.
Not trying to make light of it ... tornadoes are a serious business no matter where they make contact with the ground, but not sure why this particular instance should be national news when if it happened in the West, it wouldn't warrant a back paragraph in the national media.
As for Climate Change, I dislike the phrase, it's almost a politically correct way of avoiding the "proper" description of future climate trends. The climate is always and always has changed over time ... most extreme weather records still hold from the early and mid 20th century.
Global Warming is different, in that it's a measurable and predictable. But it also is by definition not local, so it is incorrect to suggest that it means (for example) more extreme weather for any one region. Canada has always experienced tornadoes, and Canada's deadliest happened in 1905.
