Several municipalities across Canada offer financial assistance through partial subsidies for basement flood reduction measures. Subsidy programs have been developed by some municipalities, with the goal of increasing homeowner uptake of measures including downspout and foundation drain disconnection, backwater valve installation, and repairing sewer laterals.
Subsidy programs may be available to everyone in a city, only to individuals who have experienced basement flooding, or to homeowners who are in an area that may be vulnerable to basement flooding. Grant programs are often directed to properties that have experienced flooding from sewer backup associated with the city sewer system, rather than flooding associated with infiltration or overland flows.
