It would be foolish to dismiss electromagnetic (EMG) radiation as not presenting a probable (if undefined) hazard to humans.
But it is even sillier to declare downtown Sidney as dangerous due to such microwave or WiFi coverage.
It is unlikely the writer walks to Sidney from Central Saanich. He probably drives here, thereby ignoring the much greater danger to himself of injury or death in traffic. When microwave radiation is proven responsible for the equivalent of a tiny fraction of the 1,741 Canadian traffic fatalities (2013 annual total), it will be time for alarm.
Until then, we should remain calm. Perhaps gridlock or carbon monoxide is giving him those headaches.
