Ontario is hanging up on a call to slap health warning labels on all cellphones sold in the province.

NDP health critic France Gelinas introduced a private member’s bill yesterday that would require a sticker on every cellphone warning of an increased risk of cancer.

The government promptly indicated it would not support the move.

Cellphone manufacturers already include warnings in owner’s manuals stating that not using approved holsters could cause the device to exceed radio frequency exposure standards, which could “present a risk of serious harm.”

But the companies bury the health warning so deep inside the manual, and in print so small, most people never see it, said Gelinas.

“You really have to be dedicated to read the manual,” she said.

Health Promotion Minister Margarett Best said all the best scientific advice she’s seen says there are no health risks associated with cellphone use.
