Toronto’s expanded program is now in effect.

Toronto’s Basement Flooding Protection Subsidy Program now provides up to $6,650 per eligible property, includes higher valve and pump limits, may support a second backwater valve for homes with multiple sewer connections, and extends the application period to two years after eligible work is completed. The City determines eligibility, approval and payment.

Toronto now directs backwater-valve permit applications through its online application service. Requirements can change, so confirm the current City instructions before work begins.

Project context

Separate the contractor scope from programme approval.

The private service scope can include assessment, permit support, installation, photographs, invoices and other agreed records. The municipality or region alone decides programme eligibility and payment.

Separate the contractor scope from programme approval.

Owner handover

Preserve the complete record.

Keep pre-approval or technical review, permit, inspection, itemized invoice, proof of payment, product information, photos, application and final programme correspondence.

Project checklist

Keep the decision specific to the property.

Use the assessment, authority requirements and written scope rather than choosing from a generic product package.

No. Maximums are not guaranteed payments, and eligible cost, property history, funding and programme decisions apply.
