Wi-Fi is the second most prevalent form of wireless technology in Canada next to cell phones. The technology allows devices such as computers, smart phones, and video game consoles to communicate data wirelessly. Wi-Fi is all around us -- in schools, offices, coffee shops, homes, as well as countless other locations.
A number of media reports have suggested that Wi-Fi could be associated with a variety of health concerns. Yet, there is no convincing scientific evidence that exposure to low-level radiofrequency (RF) energy from Wi-Fi causes adverse health effects in humans.
RF energy levels from Wi-Fi equipment in all areas accessible to the general public are required to meet Health Canada's exposure guidelines. The limits specified in the guidelines are based on an ongoing review of thousands of published scientific studies on the health impacts of RF energy. Based on scientific evidence, Health Canada has determined that exposure to low-level RF energy, such as that from Wi-Fi equipment, is not dangerous to the public.
RF energy coming from Wi-Fi devices is similar to that emitted from commonly used household products such as cordless phones, video game controllers, remote controls for garage door openers, and baby monitors.
Industry Canada is the federal regulator responsible for the approval of RF communications equipment and performing compliance assessments, to ensure that public RF exposures fall within acceptable guidelines. Industry Canada has chosen the human exposure limits established by Health Canada as their exposure standard.
