Floods can happen with or without warning and may be caused by nature or man. Know what the risks are for your area and prepare accordingly.

Remember that even if you live in the city and do not live near a lake, river or other body of water that there is still the risk of flooding.

There are many, many miles of underground pipes, and there are a number of them that are aging and can burst, giving you the surprise of the day you weren't hoping for. Have a look here to see what happened in Montreal, Quebec in January 2009.


Even though personally I feel that buying an inflatable boat in particularly risky areas can be an option, beware of the shortcomings. At Walmart for under $30.00 U.S. you can get one. I wouldn't sail the Seven Seas with it, or cross a lake with it, but it may be enough to keep you from going for a swim down the street or other smaller and less dangerous areas. At that price it is a toy to all intents and purposes.

There are different prices of course for inflatable boats depending on the brand, size, features and quality. Purchase one that you feel would suit your needs and your budget, but if there is any real degree of danger such as deep water and debris that could puncture a cheap, single chambered one, get something that will tackle these challenges.

You must consider getting a quality inflatable if you live on an island such as Montreal or other area where you are mainly surrounded by water.

Bridges and tunnels may be inaccessible due to heavy traffic or may be out altogether because of severe damage in a disaster.

If you do not want to be stuck in a major metropolitan area where there is no electricity or water, and where the majority of people probably haven't taken thought about stocking up and where looting and violence may be prevalent, get a boat to leave the place. Save yourself and your family should it ever get that bad. But there are risks, and it is YOUR decision to make.

Of course you'll need to weigh the risk of crossing any waters, particularly if the time of year is when the water will be cold or even not so cold because hypothermia can happen in water as warm as 24˚ Celsius.

It is best to not take too many risks. Make a good judgment call and consider your family, the ages involved and if they can swim, do any have physical handicaps, how many family members there are, your equipment including life jackets and other security items etc. before seriously considering to cross an expanse of water.

The more you are, the more equipment and other provisions you normally should have with you. You may need a bigger boat or more than one. There may be strong currents and a shipping lane or other busy area, so beware. There may also be debris in the water that may burst the inflatable, even though some have more than one air chamber.

Depending on the amount of equipment you'll be carrying and how you'll carry it, you may attract unwelcomed attention to other people which could potentially endanger you if they are looters.

It would have to be a pretty serious disaster I think before you should really consider leaving in such manner. If you own a good, regular solid hull boat and that it is there and you can access it, all the better.

It is your responsibility to determine if it is feasible to leave by boat, not me.

Emergency preparations is not about being paranoid, but being provident while sanely assessing the potential hazards that may occur in your area, and to prepare accordingly. I am not suggesting to purchase an inflatable boat if you live in the desert as an example. Do what you feel is right, and think about and plan how you would do things if a flood (or other emergency) happens.

I do not advise hasty actions, but simply to consider your options. Make up your own mind about what to do.

The comments above are my own, and no-one else's.

Floods in Canada

Flood Disasters in Canada (NRCan Database)

Floods are the most frequent natural hazard in Canada. They can occur at any time of the year and are most often caused by heavy rainfall, rapid melting of a thick snow pack, ice jams, or more rarely, the failure of a natural or man-made dam.

Flood facts

  • A heavy rainfall can result in flooding, particularly when the ground is still frozen or already saturated from previous storms.
  • Flash flooding – in which warning time is extremely limited – can be caused by hurricanes, violent storms or dams breaking.
  • All Canadian rivers experience flooding at one time or another. The potential for flood damage is high where there is development on low-lying, flood-prone lands.

Preparing for a flood

To reduce the likelihood of flood damage

  • Put weather protection sealant around basement windows and the base of ground-level doors.
  • Install the drainage for downspouts a sufficient distance from your residence to ensure that water moves away from the building.
  • Consider installing a sump pump and zero reverse flow valves in basement floor drains.
  • Do not store your important documents in the basement. Keep them at a higher level, protected from flood damage.
  • If you have a livestock farm, remember that livestock have a natural “move away instinct” to flash flood waters. They generally seek higher ground if possible. When purchasing or designing your livestock operation, it is important to allow livestock a way to reach high ground in each pasture. Without access, livestock will fight fences and be at a greater risk of drowning. Livestock will initially panic during flash floods. This complicates livestock handling.

If a flood is forecast

  • Turn off basement furnaces and the outside gas valve.
  • Take special precautions to safeguard electrical, natural gas or propane heating equipment.
  • If there is enough time, consult your electricity or fuel supplier for instructions on how to proceed.
  • In floods, in a rural farm setting, sheltering livestock may be the wrong thing to do. Leaving animals unsheltered is preferable because flood waters that inundate a barn could trap animals inside, causing them to drown.
  • If evacuation of the animals is being considered, then evacuation procedures, places, and routes should be planned. Animal evacuation routes must not interfere with human evacuation routes. Alternate routes should be found in case the planned route is not accessible. Places where animals are to be taken should be decided in advance and arrangements made with the owners of these places to accept the animals.

If flooding is imminent

  • Move furniture, electrical appliances and other belongings to floors above ground level.
  • Remove toxic substances such as pesticides and insecticides from the flood area to prevent pollution.
  • PRemove toilet bowls and plug basement sewer drains and toilet connections with a wooden stopper.
  • Disconnect eavestroughs if they are connected to the house sewer.
  • In some cases, homes may be protected with sandbags or polyethylene barriers. This approach requires specific instructions from your local emergency officials.
  • Do NOT attempt to shut off electricity if any water is present. Water and live electrical wires can be lethal. Leave your home immediately and do not return until authorities indicate it is safe to do so.

During a flood

  • Keep your radio on to find out what areas are affected, what roads are safe, where to go and what to do if the local emergency team asks you to leave your home.
  • Keep your emergency kit close at hand, in a portable container such as a duffel bag, back pack, or suitcase with wheels.

If you need to evacuate

  • Vacate your home when you are advised to do so by local emergency authorities. Ignoring such a warning could jeopardize the safety of your family or those who might eventually have to come to your rescue.
  • Take your emergency kit with you.
  • Follow the routes specified by officials. Don't take shortcuts. They could lead you to a blocked or dangerous area.
  • Make arrangements for pets.
  • Time permitting, leave a note informing others when you left and where you went. If you have a mailbox, leave the note there.

Never cross a flooded area

  • If you are on foot, fast water could sweep you away.
  • If you are in a car, do not drive through flood waters or underpasses. The water may be deeper than it looks and your car could get stuck or swept away by fast water.Avoid crossing bridges if the water is high and flowing quickly.
  • If you are caught in fast-rising waters and your car stalls, leave it and save yourself and your passengers.

After a flood

Restore your home to good order as soon as possible to protect your health and prevent further damage to the house and its contents. The Canada Mortgage and Housing Corporation has prepared a checklist to help organize your cleanup. It is also available by calling 1-800-668-2642 (outside Canada call 613-748-2003).

Re-entering your home

  • Do not return home until authorities have advised that it is safe to do so.
  • If the main power switch was not turned off prior to flooding, do not re-enter your home until a qualified electrician has determined it is safe to do so.
  • Use extreme caution when returning to your home after a flood.
  • Appliances that may have been flooded pose a risk of shock or fire when turned on. Do not use any appliances, heating, pressure, or sewage system until electrical components have been thoroughly cleaned, dried, and inspected by a qualified electrician.
  • The main electrical panel must be cleaned, dried, and tested by a qualified electrician to ensure that it is safe.
  • Depending on where you live, your municipal or the provincial inspection authority is responsible for the permitting process required before your electric utility can reconnect power to your home.

Ensure building safety

  • Make sure the building is structurally safe.
  • Look for buckled walls or floors.
  • Watch for holes in the floor, broken glass and other potentially dangerous debris.


  • Flood water can be heavily contaminated with sewage and other pollutants. It can cause sickness and infections.
  • If through colour, odour or taste you suspect that your drinking water has been contaminated, don't drink it.
  • Household items that have been flood-damaged will have to be discarded according to local regulations.


  • Store all valuable papers that have been damaged in a freezer until they are needed (After your cleanup, consult your lawyer to determine whether flood-damaged documents, or just the information in them, must be retained).
  • Record details of flood damage by photograph or video, if possible.
  • Register the amount of damage to your home with both your insurance agent and local municipality immediately.


Maintain good hygiene during flood cleanup. Minimize contact with floodwater or anything that may have been in contact with it. Keep children away from contaminated areas during cleanup operations.

Recommended flood cleanup equipment

  • Gloves
  • Masks and other protective gear
  • Pails, mops and squeegees
  • Plastic garbage bags
  • Unscented detergent
  • Large containers for soaking bedding, clothing and linens, and clotheslines to hang them to dry

Additional equipment

  • Depending on your situation, you may need to rent additional equipment such as extension cords, submersible pumps, wet/dry shop vacuums, a carbon monoxide sensor and dehumidifiers, fans or heaters.
  • When using the equipment, keep extension cords out of the water.


  • Remove water from your flooded home slowly. Drain it in stages – about one third of the volume daily – because if the ground is still saturated and water is removed too quickly, the walls or the floor could buckle.
  • Use pumps or pails to remove standing water, then a wet/dry shop vacuum to mop up the rest.
  • For instructions on how to disinfect and restore wells and cisterns, contact your local or provincial health authorities or emergency management organization.

Heating and appliances

  • Do not heat your home to more than 4°C (about 40°F) until all of the water is removed.
  • If you use pumps or heaters powered by gasoline, kerosene or propane, buy and install a carbon monoxide sensor. Combustion devices can produce large amounts of lethal carbon monoxide if they're not tuned-up or are improperly ventilated.
  • Do not use flooded appliances, electrical outlets, switch boxes or fuse-breaker panels until they have been checked by your local utility.
  • Whether you use a wood, gas or electrical heating system, have it thoroughly inspected by a qualified technician before using it again. Replace the furnace blower motor, switches and controls if they have been soaked.
  • Flooded forced-air heating ducts and return-duct pans should be either cleaned or replaced.
  • Replace filters and insulation inside furnaces, water heaters, refrigerators and freezers if they have been wet. However, it is often cheaper to replace this equipment.

Dirt and debris

  • Remove all soaked and dirty materials as well as debris.
  • Break out walls and remove drywall, wood panelling and insulation at least 50 centimetres (20 inches) above the high-water line.
  • Hose down any dirt sticking to walls and solid-wood furniture then rinse several times.
  • Wash and wipe down all surfaces and structures with unscented detergent and water. Rinse.

Floor drains

  • Flush and disinfect floor drains and sump pumps with detergent and water. Scrub them to remove greasy dirt and grime.
  • Clean or replace footing drains outside the foundation when they are clogged. Consult a professional for advice or service.


  • Ventilate or dehumidify the house until it is completely dry.
  • Rinse and then clean all floors as quickly as possible.
  • Replace flooring that has been deeply penetrated by flood water or sewage.
  • Clean all interior wall and floor cavities with a solution of water and unscented detergent.

Carpets and furniture

  • Carpets must be dried within the first two days. For large areas, hire a qualified professional to do the job. Carpets soaked with sewage must be discarded immediately.
  • Remove residual mud and soil from furniture, appliances, etc.
  • If items are just damp, let the mud dry and then brush it off.
  • To test if material is dry, tape clear food wrap to the surface of the item. If the covered section turns darker than the surrounding material, it is still damp. Dry until this no longer occurs.
  • For upholstered furniture you should consult a professional to see what can be salvaged. In the meantime, remove cushions and dry separately. Do not remove upholstery. Raise furniture on blocks and place fans underneath.
  • Wooden furniture: Remove drawers and open doors. Do not dry quickly or splitting may occur.


  • Mould can lead to serious health problems.
  • You may need to have your home professionally cleaned for it to be covered by insurance. Check with your insurance company.
  • If you are cleaning up in a room where mould is present, wear a face mask and disposable gloves.
  • To minimize mould growth, move items to a cool, dry area within 48 hours and set up fans.
  • Alternatively, textiles, furs, paper and books can be frozen until they are treated.
  • Wet mould will smear if wiped. Let it dry and then brush it off outdoors.
  • You can also kill mould spores by lightly misting the item with isopropanol (rubbing alcohol).

Food and medicine

  • All undamaged canned goods must be thoroughly washed and disinfected.
  • Dispose of all medicines, cosmetics and other toiletries that have been exposed to flood water.
  • Dispose of any of the following food items if they have been exposed to flood water:

- Contents of freezer or refrigerator, including all meats and all fresh fruit and vegetables

- All boxed foods

- All bottled drinks and products in jars, including home preserves (since the area under the seal of jars and bottles cannot be properly disinfected)

- Cans with large dents or that reveal seepage

What to discard

  • All insulation materials, particleboard furniture, mattresses, box springs, stuffed toys, pillows, padding, cushions and furniture coverings that have been exposed to flood water.


What is salvageable

  • Frames of high-quality furniture can often be saved. However, they must first be cleaned, disinfected and rinsed, then dried by ventilation away from direct sunlight or heat. Drying too quickly can cause warping and cracking.
  • Clothes can be cleaned. Scrape heavy dirt from washable clothes. Rinse and wash them several times with detergent and dry quickly.

Before moving back in

  • Once the flood waters have receded, you must not live in your house until:
  • The regular water supply has been inspected and officially declared safe for use.
  • Every flood-contaminated room has been thoroughly cleaned, disinfected and surface-dried.
  • All contaminated dishes and utensils have been thoroughly washed and disinfected – either by using boiling water or by using a sterilizing solution of one part chlorine bleach to four parts water. Rinse dishes and utensils thoroughly.
  • Adequate toilet facilities are available. (For more information, consult your local health authority.)
