Flood Insurance

No. Overland water (flood) insurance is not included in standard BC home insurance policies and must be added as a separate endorsement. Homeowners should contact their insurer directly to confirm whether this coverage is available for their specific property and what the endorsement terms require.

The Province of BC and local governments publish floodplain maps that identify designated flood-hazard areas, and private insurers reference these maps when making underwriting decisions. Properties situated within mapped floodplains — such as portions of Sumas Prairie, Chilliwack, Pemberton, and Squamish — may be deemed uninsurable for overland water coverage or may face significantly higher premiums. Buyers of properties in these areas should obtain a flood-hazard assessment and confirm insurability with an insurer before completing a purchase.

Overland flood insurance covers damage caused when water enters a property at ground level from sources such as rivers overflowing their banks, snowmelt runoff, or heavy rainfall pooling on the surface. It does not typically cover sewer backup (which requires its own separate endorsement) or damage from groundwater seepage, though exact exclusions vary by policy. Homeowners should review their policy wording carefully to understand the precise scope of coverage.

Under the Real Estate Services Act (RESA) and the rules administered by the BC Financial Services Authority (BCFSA), licensees owe clients a duty of full and timely disclosure of all known material latent defects and relevant information that could affect a buyer's decision. Known flood-hazard designations or a history of flood damage to a property would generally be considered material information that a licensee must disclose. Licensees should also advise buyers to independently verify flood-hazard status using provincial and municipal floodplain maps.

Under the Strata Property Act (SBC 1998, c. 43), a strata corporation is required to obtain and maintain property insurance on common property, common assets, and the structure of strata lots against major perils. Whether overland flood coverage is included depends on the strata corporation's insurance policy, the insurability of the building's location, and any specific decisions made by the strata council. Buyers of strata lots in flood-prone areas should review the strata corporation's current insurance certificate, which can be requested through the Form B Information Certificate, to confirm what perils are covered.

The federal government has been developing a National Flood Insurance Program specifically intended to provide coverage to high-risk properties that are currently uninsurable in the private market due to their flood-hazard designation. Until such a program is fully implemented, homeowners in areas like Sumas Prairie or other mapped BC floodplains that private insurers will not cover may have limited or no options for overland water insurance. Homeowners in these areas should consult with insurance brokers and monitor announcements from the federal government regarding the program's availability and eligibility requirements.

Flood risk can materially affect a property's market value and a lender's willingness to provide mortgage financing, since most institutional lenders require that adequate property insurance be in place as a condition of the mortgage. If overland flood insurance is unavailable or prohibitively expensive for a property in a designated flood-hazard area, lenders may decline financing or impose special conditions. Buyers should confirm insurability and lender requirements before removing subjects on a purchase contract.

The Province of BC publishes flood-hazard information through the BC Flood Plain Mapping program, accessible via the BC Government website, and many local governments also maintain flood-hazard maps through their official community plans and development permit area schedules. Buyers can search the BC Ministry of Water, Land and Resource Stewardship's publicly available mapping tools or contact the relevant local government directly for site-specific flood-hazard information. Consulting a professional geoscientist or engineer with expertise in floodplain assessment may be appropriate for high-risk properties.

Properties within the Agricultural Land Reserve (ALR) are regulated under the Agricultural Land Commission Act (SBC 2002, c. 36), and any non-farm use, subdivision, or development must comply with ALR rules administered by the Agricultural Land Commission (ALC). Flood-hazard designations can interact with ALR restrictions because local governments may impose additional development permit requirements or building setbacks in mapped floodplain areas, limiting how a buyer can use or develop ALR land. Buyers of ALR properties in flood-hazard areas should independently verify applicable ALC restrictions and local government floodplain bylaws before completing a purchase.

BC real estate transactions commonly use a Property Disclosure Statement (PDS), on which sellers are asked to disclose known material defects including past water damage. A history of flood damage would typically be a material fact that must be disclosed, and concealing it could expose a seller to legal liability and could implicate the licensee's duties under RESA and BCFSA rules. Buyers who become aware of past flood damage should investigate the extent of any remediation, confirm current insurability, and consider including appropriate conditions in their offer.
