Health Canada is responsible for conducting research into potential health effects of wiress technology, and has published guidelines setting out safe human exposure levels to RF electromagnetic energy.

The Government of Canada’s role

Health Canada’s role is to protect the health of Canadians, so it is the Department’s responsibility to research and investigate any possible health effects associated with exposure to RF energy, such as that coming from Wi-Fi equipment. Health Canada has developed guidelines for safe human exposure to RF energy (Safety Code 6). It is one of a series of codes that specify the requirements for the safe use of radiation-emitting devices operating in the frequency range from 3 kilohertz (kHz) to 300 gigahertz (GHz). Wi-Fi operates in the 2.4 and 5.8 GHz frequency range.

Wireless devices such as Wi-Fi equipment are regulated by Innovation Science and Economic Development Canada (ISED). This department also oversees the licensing and placement of cell phone towers, considers the effects on the environment and local land use before towers are installed, and ensures that these towers comply with regulatory requirements. ISED has adopted part of Health Canada’s RF exposure guidelines to protect the general public by ensuring that exposure from cell phones and cell phone towers do not exceed the specified limits.

The current version of the Safety Code 6 guidelines are available at, and titled Limits of Human Exposure to Radiofrequency Electromagnetic Energy in the Frequency Range from 3 kHz to 300 GHz – Safety Code 6 (2015).

The guidelines are accompanied by a companion document Technical Guide for Safety Code 6: Health Canada’s Radiofrequency Exposure Guidelines.

Both documents are also available as PDFs from Government of Canada links below…
