A group of Ontario Catholic school teachers is calling for an end to Wi-Fi in the province’s classrooms over potential health concerns.

The Ontario English Catholic Teachers Association says it wants all new computers to be hardwired, instead of using a wireless network.

“Let's get some clarity. It's relatively new technology in classrooms. A lot of exposure to students…it’s the young children who actually have the greatest exposure to this potential health risk,” said the association’s Kevin O’Dwyer.

The association, which represents 45,000 teachers, released a position paper Monday citing research by the World Health Organization (WHO).

The WHO previously issued a warning about radiation from wireless devices like cell phones or MP3 players and possible links to cancer.

But despite the suggestion, many say the evidence isn’t strong enough.

“Everything has a health concern right, regardless if it’s a cell phone, or computer. It’s the same issue,” said one parent.

“I’m not concerned at all, I’m sure they have protection,” said another parent.

The Toronto District Catholic School Board says it relies on information from Toronto Public Health, which says Wi-Fi is not a real danger.

“I in fact released an opinion on this last year, and the weight of the evidence does not support health effects associated with exposure to radio frequency energy, which is either Wi-Fi or cell phones,” said Dr. Arlene King, Chief Medical Officer of Health, Ontario back in 2011.

Last year, a group of parents in York region staged a protest over Wi-Fi in their children’s schools.
