Information Update on the Fukushima Daiichi nuclear accident: No radiation at harmful levels reached Canada

On March 11, 2011, the Great East Japan Earthquake triggered a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Japan. The accident culminated in significant releases of radioactive contaminants into the environment beginning March 12, 2011. The emissions were of significant domestic concern in Japan and resulted in low but measurable levels of radioactive contaminants world-wide. The damaged nuclear power reactors in Japan do not pose a health risk to residents of British Columbia or the rest of Canada.

The following text provides a summary of the monitoring and assessment undertaken by Health Canada in response to the Fukushima Daiichi nuclear accident and includes links to additional information sources.

Health Canada's Environmental Radiation Monitoring

The Government of Canada is committed to protecting the health and safety of Canadians. To this effect, Health Canada's Radiation Protection Bureau has been monitoring environmental radioactivity on a routine basis since 1959. It currently operates two radioactivity monitoring networks which represent a total of over 100 detection and sampling stations located all over Canada. One of these networks is part of a larger global radiation monitoring network overseen by the United Nation's Comprehensive Nuclear Test Ban Treaty Organisation. These networks are extremely sensitive and can provide an indication of any potential problem with respect to radioactivity in air and precipitation.

For recent information on radiation monitoring in Canada, data from Health Canada's networks can be found on the Radiation Dose Data from the Fixed Point Surveillance Network page.

Health Canada continues to monitor and review radiation levels in Canada and worldwide, using its monitoring networks and its collaborative relationships with the international community.  Measurements from Health Canada's networks confirm that the quantities of radioactive materials that reached Canada as a result of the Fukushima Daiichi nuclear accident were very small and did not pose any health risk to Canadians.  Should data from our monitoring programs indicate a need for additional efforts, Health Canada will promptly notify the Public Health authorities (including provincial authorities) of the situation and provide guidance on how to best address the issue/concern.

Radiation in Food, Seafood and Ocean Water

Detailed information on radiation from Japan, including radiation levels in food products, seafood, and ocean water, can be found on the Additional information on radiation from Japan webpage. Information from all of these sources indicates that radiation levels resulting from the Fukushima accident are far below levels of concern to public health in Canada.

Food safety issues are a joint responsibility between the Provincial authorities and the Canadian Food Inspection Agency (CFIA) which regulates food producers.  Health Canada is actively supporting the CFIA in its mandate for food safety which includes ensuring that radiation levels in food are below levels of concern. Details can be found on the  CFIA website.  For questions regarding food safety, please  contact the CFIA.

For information on the debris from the Japan tsunami, please consult the  Tsunami Debris Coordinating Committee.

For questions regarding regulation of the nuclear industry in Canada, please contact the Canadian Nuclear Safety Commission at

Information on the status of the Fukushima Daiichi Nuclear Power Station, as published by Japan's Nuclear Regulation Authority, is available through the  International Atomic Energy Agency.

For information on radiation monitoring in the United States, please consult the  US Environmental Protection Agency.  Information on marine debris is also available from the  US National Oceanic and Atmospheric Administration.
