Mississauga’s programme architecture separates plumbing and drainage prevention from water-resilient building improvements. Residents may also need to review Region of Peel’s separate sanitary backwater-valve programme.

Frequently asked questions
Programme and local-resource questions
Does RSM approve this rebate?
No. The municipality or region administers the programme and determines eligibility.
Should work begin before approval?
Not unless the current official programme clearly permits it. Many programmes require pre-approval, permits or pre-work inspection.
Does the maximum amount mean every applicant receives that amount?
No. Payment depends on eligible costs, measure limits, inspections, available funding and the authority’s decision.
Does rebate eligibility prove the proposed system is technically suitable?
No. Funding eligibility and property-specific technical suitability are separate questions.
Before planning work
Verify the current official programme.
Programme status, amounts, eligible properties, pre-approval, permits, inspections and funding can change. Obtain written confirmation before incurring costs.
