Hazard information

Floods are the costliest natural hazard in terms of property damage in Ontario. Floods are typically caused by melting snow, ice jams, high lake levels, and heavy rains and thunderstorms. They can happen at any time of year and in urban and rural areas. Flash flooding can occur in rain storms or when a storm drain is plugged — often with little or no warning.

Flood forecasting and warning program

Flooding in Ontario is caused by extreme rain, rapid snowmelt, lake/storm surge or ice jams.

Safety tips

If you are instructed by emergency officials to evacuate, do so immediately.

  • disconnect electrical appliances — don’t touch electrical equipment if wet or standing in water
  • don’t eat food that’s come in contact with flood waters
  • ensure your cellphone is charged (safely) — it may be your only means of communication during an evacuation

If you are outdoors:

    • and your electricity is on, leave the area immediately
    • follow your emergency plan and move to a safe place on higher ground
    • avoid travelling on roads that are near water, bridges, ravines, embankments, low laying areas and any bodies of water
  • don’t drive through, stand or walk in any moving water — you may fall
  • if you must walk, look for where the water is not moving and use a stick to check the ground in front of you
  • account for all of your family members, keeping children and pets away from floodwaters

Before a flood

Be prepared for an emergency by creating a 72-hour emergency preparedness plan and kit for you and your family.

Inside your home:

  • store any personal belongings in sealed bins
  • move documents and keepsakes out of the basement
  • test sump pumps regularly and install a back-up system (for example, battery back-up or generator)
  • put weather protection sealant around basement windows and ground-level doors

Outside your home:

  • extend downspouts at least 2 metres from your home to move water away from the building
  • remove debris that could present danger during flood events
  • secure outdoor furniture and items around piers, docks or boathouses
  • regularly maintain water drainage systems, such as weeping tile, culverts and ditches
