Be prepared before an emergency happens

  • Know the risks in your community and region. You can find information on your local municipality’s website to help you further understand the risks in your local area.
  • Make a plan so you and your family know what to do. Include a meeting place, emergency contacts, and evacuation routes.
  • Listen to the latest warnings and advisories on the radio, television, or reliable sources on social media or the internet. Examples of reliable sources include your local municipality, conservation authorities, and the Ministry of Natural Resources and Forestry.
  • Prepare your home for a possible evacuation and gather essential items such as cash, medications, important documents, identification and clothing.
  • Move valuables out of basements and lower levels.
  • Keep your cell phone charged in case it becomes your only communication tool.
  • Be ready to place pets in a kennel, as evacuation centres may not accept animals.
  • Keep your vehicle fueled.
  • Evacuate immediately if instructed to do so and assist children, older adults, and people with disabilities.
  • Secure boats and loose items around docks, piers, and boathouses.
  • Prepare a 72‑hour emergency kit with food, water, a flashlight, radio, extra batteries, emergency numbers, non‑perishable food and prescription medications. Make a kit for pets as well.

During and after an emergency

  • Flooding can make food, water, and living spaces unsafe. Follow updates and recommendations from local authorities.
  • Emergencies can cause stress and trauma. Knowing what services are available in your community can help during recovery.

Drinking water and flood safety

Flood water often contains bacteria, chemicals, and other contaminants, so drinking water advisories (DWAs) are issued when water may be unsafe to prevent water‑borne illness. Following basic water‑safety precautions is essential for protecting you and your family. Private wells are at increased risk of contamination during floods, and any well can become unsafe. If flood water has reached or covered your well head, you should assume the water is not safe to drink. During these situations, it’s important to follow all drinking water advisories and rely on safe water sources until your well has been properly tested and confirmed safe.
