Potassium Iodide (KI) Distribution

The Canadian Nuclear Safety Commission (CNSC) has mandated that all residents within the primary zone of a nuclear installation have potassium iodide tablets available in their homes.

It is important to point out that the risk has not changed at Fermi 2 or Davis-Besse, however what has changed is the regulatory framework for Canadian nuclear installations.

If you have previously obtained KI pills, check their expiry date. If your KI pills have an expiry date of March 2025, it’s time to replace them.

Potassium Iodide (KI) Pill Request

Please Note: The mail out option is no longer available as the KI Pills are temperature sensitive. The portal will reopen Spring 2025.

In-person pick-up is available at select locations (see below).

After receiving new KI pills, residents can safely throw out expired KI pills in their household garbage or drop them off at their local pharmacy.


While neither nuclear installations are regulated by the CNSC, the Windsor-Essex County Health Unit and the local municipalities want the residents living within the primary zone and secondary zones to be treated the same and be as prepared as all other Canadian residents living near a nuclear installation.
