Seems like this anti-wifi hysteria is really big in Canada. I wonder why. Is it just that the leading proponents happen to live there?
There was a pretty big group in Ontario who made a real fuss about wi-fi in schools, I believe they were the first to do so. They were backed by the "Ontario English Catholic Teacher's Association," which represents a pretty considerable number of teachers, and a national news story was born.
My other theory is that Canada, on account of its tiny population relative to its landmass, has enough remote communities (or big enough parks in urban centres) to prevent the theory from being dismissed outright. If you're living in LA or the eastern seaboard, you are going to be bathed in pretty much uniform "radiation" such that the claim that you can tell when wi-fi is turned on in a house is completely impossible.
Up here, with several hours drive between cities (and obvious wi-fi sources), there is at least the ring of plausibility to the claim that a person can tell the difference.
My final theory is that with universal health care, its way easier to make ridiculous claims when you aren't paying deductibles or premiums or risking the dreaded "pre-existing heart disorder" finding on the record.
