In the very unlikely event of an emergency that results in a release of radiation to the public, the Chief Medical Officer of Health for Ontario will provide instructions through radio, TV, Internet and other available channels on where, when, how, and by whom KI should be taken.

It is important to wait for this notification. Do not take the pills unless instructed to do so. You would only need to take the pills for a short period of time, likely 1 – 2 days.
