Two weeks after leaving Port Franks on a march to Ottawa, 57 year-old grandmother Brenda Hoy arrived in Oakville on Thursday almost half-way to Parliament Hill, raising awareness about her fight for tougher regulations around radiation emitted from cell towers, cell phones, and WiFi.

She says were are surrounded by the harmful effects of these technologies and often don't even know it.

"There's so many more devices being sold to people and they're carrying them around on them exposing themselves and all the people around them," says Hoy. "I'd like to see that involuntary exposure aspect be limited.

She was joined in Oakvile Thursday morning by Conservative MP Terence Young and former Microsoft Canada president Frank Clegg.

Clegg says Canada's regulations are outdated.

"We're just deploying this technology at an incredibly rapid pace and there's nobody really taking a step to say 'okay are we really studying the impacts of constant exposure to young minds and young bodies' "?

Health Canada says WiFi is fine, while a World Health Organization agency says what's emitted by WiFi devices could possibly cause cancer.
