Industry Canada (IC) is the Canadian regulator of radio communication and broadcasting installations and apparatus, and has jurisdiction over cell phone tower installation and placement. To ensure that public exposures fall within acceptable guidelines, Industry Canada has developed regulatory standards that require compliance with portions of the radiofrequency (RF) exposure limits recommended in Health Canada’s Safety Code 6. If you would like more information about the compliance of a specific cellular tower, you can contact them at firstname.lastname@example.org. If you would like to contact your regional office, you can reach them through the following link http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf01742.html
As part of Industry Canada’s mandate, it has established the process that must be followed by proponents seeking to install or modify antenna systems, which may include public consultations.
Health Canada's mandate on the issue of human exposure to radiofrequency (RF) electromagnetic energy, such as those from cell phones and other wireless devices is to
Based on all the available scientific evidence, Health Canada has concluded that the levels specified in Safety Code 6 are well below the threshold for any potential harm. Safety Code 6 is current and valid for protecting the health and safety of Canadians, including children and the most vulnerable. The RF exposure limits specified in Safety Code 6 have been established through careful evaluation of the scientific literature on both thermal and non-thermal effects of RF energy on biological systems. Safety factors have been incorporated into these limits to add an additional level of protection.
The limits in Safety Code 6 take into account the total RF exposure from all sources of RF energy. For example, in a given area, the combined RF energy from all cell towers and other wireless infrastructure are not to exceed the limits in Safety Code 6. Therefore, no adverse health effects are expected from exposure to RF emitting devices if the devices adhere to Safety Code 6. This is the case for the cellular tower and your cellular telephone.
The International Agency for Research on Cancer (IARC) classified RF energy as “possibly carcinogenic to humans” (Class 2B) in May 2011, based on limited evidence that it might increase the long-term risk of brain cancer incidence for long term/heavy cell phone users. However, the vast majority of scientific research to date does not support a link between RF energy exposure and human cancers. A Health Canada scientist was a member of the IARC Expert Working Group that examined this issue. As a result, Health Canada recently updated its advice pertaining to cell phone use to be more precautionary (e.g. limit the length of cell phone calls, and use text messaging or hands-free options when possible).
The Department does not consider additional precautionary measures for other wireless devices, such as cell phone towers and WiFi equipment, to be warranted at this time, since the intensity and distribution of the RF energy absorbed within the body from these devices are very different from that of cell phones and health risks from exposure below the limits specified in Safety Code 6 have not been established. However, it is in agreement with both the World Health Organization and IARC that additional research in this area is warranted.
