Parents are asking an elementary school in Meaford, Ont., to shut down Wi-Fi internet access over health concerns, although authorities say there is no scientific evidence the technology is harmful.

"This is something every school council across Canada should be questioning," Andrew Couper, a member of Saint Vincent Euphrasia Parent Council, said in a statement issued Monday.

The parents group has about 210 members, and 88 per cent of those who were asked in a survey said they want the Wi-Fi shut off, Couper said in an interview.

The parents believe Wi-Fi at the school, which has about 350 students, is giving the children symptoms that include headaches and an inability to concentrate, all of which disappear on weekends.

A number of schools have debated banning Wi-Fi over similar concerns. Health Canada issued an advisory in August, when the issue initially surfaced, stating that wireless internet is not harmful to anyone's health.
