Health Department reminds residents and businesses near nuclear generating stations to obtain supply of KI tablets

WHITBY, ON May 08, 2017 - In recognition of Emergency Preparedness week, Durham Region Health Department is reminding area residents and businesses as well as residents who are new to the Region to ensure that they have their supply of Potassium Iodide (KI) tablets readily available.

KI is a stable iodine salt, effective in reducing the risk of thyroid cancer in the event of a radioactive iodine release. As directed by the Canadian Nuclear Safety Commission (CNSC), all homes and businesses within the 10-kilometre primary zone surrounding a nuclear generating station must be provided with KI tablets, to be used in the highly unlikely event of a nuclear emergency involving the release of radioactive iodine. KI tablets should only be taken when instructed by Ontario’s Chief Medical Officer of Health in the event of a nuclear incident.

“In October 2015, the Health Department and Ontario Power Generation launched a campaign to implement the CNSC’s directive of providing KI tablets to all homes and businesses within the 10-kilometre primary zone,” explains Ken Gorman, Director of Environmental Health with the Health Department. “The campaign resulted in the distribution of KI tablets to over 200,000 homes and businesses located in the primary zone in 2015. This current public awareness campaign is to encourage area residents and businesses to confirm that they have their supply of KI tablets and also to ensure that anyone who is new to the area is aware of the availability of KI tablets for their residence or business.”

KI tablets are also available to anyone living within the 50-kilometres secondary zone of a nuclear generating station.

KI can be obtained by visiting, or by calling the Health Department Environmental Help Line at 905-723-3818 or 1-888-777-9613. In addition, KI tablets are also available free of charge at the following pharmacies that have partnered with the Health Department to help with distribution:

  • Bay Ridges Pharmacy, 1794 Liverpool Rd., Pickering
  • Pickering Medical Pharmacy, 1885 Glenanna Rd., Pickering
  • Liverpool Pharmacy, 725 Krosno Blvd., Pickering
