Flood risk and home insurance when downsizing in Waterloo

Insurance is easy to leave until the week before closing, and that order can cost you options. A home that is hard to insure, or that needs an inspection before a policy is issued, is better discovered while your offer still has conditions. Introductions from Waterloo Downsizing go to agents on the operating team at eXp Realty, so this is not a search of the whole market, and nothing here replaces a broker, a lawyer or the agencies named below.

This guide is general information, not insurance, legal or engineering advice. Policies differ by insurer and address. Confirm every point with a licensed insurance broker and your lawyer for the home you are buying.

The Grand River watershed and the GRCA

Most of Waterloo Region and Wellington County drains toward the Grand River and its tributaries, and the Grand River Conservation Authority (GRCA) is the body that maps and regulates the hazard areas along them. GRCA describes the floodplain as the area covered by the greater of two events: the Hurricane Hazel (Regional) storm or the 100-year flood. Its flooding page also notes that dikes protect parts of Kitchener (Bridgeport), Cambridge (Galt) and Brantford.

A dike reduces risk in the area it protects. It does not remove the need to ask about the address, and it does not change what your policy covers.

What a regulated area is and how to check an address

GRCA regulates river or stream valleys including their floodplains and slopes, wetlands and the Lake Erie shoreline. It states that the regulation still applies whether these areas are mapped or not. That wording matters for a buyer: the map is a starting point, not a guarantee.

To check a property, open GRCA's Map Your Property tool and search by address. We do not say here whether any street or neighbourhood is or is not in a flood plain, because that answer belongs to the map and to GRCA staff. If the result is close to a boundary, ask GRCA to confirm in writing and pass the answer to your lawyer. The same lookup is useful for a house you are selling, since a buyer's agent will check it.

The neighbourhood guides link to the same tool for each area, including Kitchener and Cambridge.

The three flood message levels

GRCA issues flood messages in three levels, described on its flood warning system page. You can subscribe by email, and GRCA also posts to X at @grca_flood_msg.

Whoever lives in the home, whether you or a parent, should be on the list before the first spring thaw. Municipal alerts are a separate system, covered below.

Permits for work in regulated areas

If you are buying a house in a regulated area and plan work, or selling one and a buyer wants to add something, a GRCA permit may be needed. GRCA's permits page says a permit under Ontario Regulation 41/24 is needed for building and structures, additions, garages, sheds, grading, fill, pools, septic systems and driveways in regulated areas. Applications go through GRCA's online permit portal, and the page lists a permits email and phone line.

For a downsizer this shows up in small ways: a ramp, a deck repair, a new garage door opener bay or a shed. Ask before hiring a contractor, and ask the seller whether any past work had a permit.

The Laurel and Clair Special Policy Area in Waterloo

The City of Waterloo Official Plan states that there is one Special Policy Area in the city, the Laurel/Clair Special Policy Area. According to the plan, changes to it need approval from the Province, the City and GRCA, and development is generally not permitted in flood hazard lands. The boundaries, history and what the designation means for a given lot are matters for the City's planning staff and the Official Plan itself. See the Waterloo guide for the area overview.

Overland flood and sewer backup: optional cover

The Insurance Bureau of Canada (IBC) explains on its flood and water page that damage caused by the backing up of sewers and drains is typically not covered by a standard policy, and that most insurers offer optional sewer backup cover. It says overland flooding is also typically not covered by a standard policy and that many insurers now offer optional overland flood cover.

These are two different perils. Sewer backup comes up through drains. Overland flood is water coming across the ground from a river, creek or heavy rain. Ask a broker for each one separately, and ask what the limit, deductible and exclusions are for the address, especially for a finished basement.

A national flood insurance program

IBC's flood protection page describes constructive work with insurers and other partners on a potential national flood insurance program, with technical analysis under way. It does not describe a launched program. Price your purchase on what is available from insurers now.

Sump pumps and backwater valves

IBC recommends a sump pump with a battery backup and a backwater valve, and says some municipalities may offer subsidies. The City of Waterloo's backflow page lists permit and test report fees and covers devices in commercial and multi-residential buildings. Whether the City of Waterloo, Kitchener, Cambridge, a township or the Region offers one is a question for that municipality.

• Ask the seller whether there is a sump pump and a backwater valve, who installed them and when.
• Ask whether the pump has a battery backup and whether it has been tested.
• Ask whether any water has entered the basement, and what was done about it. A past problem can be a latent defect, so see the seller disclosure guide.
• Ask your inspector to look at lot grading, downspouts and eavestroughs. IBC lists grading and annual downspout maintenance among its flood-readiness tips.

Knob-and-tube, aluminum wiring and other older-home items

If you are selling an older home, buyers will ask insurers about it. The Electrical Safety Authority (ESA) says on its knob-and-tube page that many insurers will not provide or renew coverage on homes with this wiring because they consider it a higher risk. ESA also says the current code does not permit new installations but is not retroactive, and it recommends an assessment by a licensed electrical contractor.

On aluminum wiring, ESA says that some insurers will not provide or renew coverage without an ESA inspection. It suggests getting an ESA Certificate of Acceptance and asking your insurer what it requires. IBC adds in its guide to a home's history that insurers may require that inspection certificate, and that for galvanized or lead plumbing you should contact the municipality about testing.

Oil tanks, wood stoves and fuse panels also affect some policies. Ask a broker how each would be treated. Our guide to preparing an older home to sell covers the seller's side.

Radon testing

Radon is a gas that can build up in a basement. Health Canada's take action on radon page gives a guideline of 200 becquerels per cubic metre and recommends a long-term test of about three months. Region of Waterloo Public Health's in the home page says to act within two years at 200 or more and within one year above 600, and points to the C-NRPP list of professionals at c-nrpp.ca. Public Health can be reached at 519-575-4400.

A three-month test rarely fits a normal conditional period, so ask the seller for past results and ask your agent how to handle testing after closing.

Alert Waterloo Region

Alert Waterloo Region is a partnership of the Region, Cambridge, Kitchener, Waterloo, North Dumfries, Wellesley, Wilmot, Woolwich and Waterloo Regional Police. You can subscribe for emergency alerts. GRCA flood messages and municipal alerts are separate, so subscribe to both. If you are helping a parent, sign them up too and add yourself as a contact where the service allows.

Condo corporation insurance and your own policy

If you are moving into a condominium, two policies are in play: the corporation's and yours. The Condominium Authority of Ontario says a status certificate includes the corporation's insurance information along with the budget, reserve fund statement, special assessments and litigation. We do not describe here what a corporation policy covers or what a unit owner policy should add, because that depends on the declaration and the policies. Ask the corporation for the insurance summary and ask your broker to read it against your unit policy. Our condo buying guide explains the certificate.

What to ask an insurance broker before an offer

• Can this address be insured, and on what terms, given its age, wiring, plumbing and heating?
• Is optional sewer backup available, and is overland flood available, for this address?
• What are the limits and deductibles for each, and are there exclusions for finished basements?
• Does the insurer need an ESA certificate, an electrical assessment or other documents, and how long will that take?
• Has the insurer declined, rated up or required changes on this address before? Ask whether the seller can share a claims history.
• For a condo, what does the corporation policy cover and what should my unit policy add?

Ask for answers in writing, and share them with your lawyer before you waive any condition. Ask your agent what a reasonable condition period looks like for your situation. The Costs and Taxes page and the step-by-step plan show where insurance fits among other closing items, and the resources page lists regulators and help lines.

If you would like a conversation with an agent about a specific move, you can ask to be introduced.
