What to know
Funding eligibility and technical suitability are different.
A programme can define eligible work, percentages, maximums and documents, but that does not mean every listed device is suitable for every home.
Project context
Pre-approval and permit timing can control the sequence.
Markham requires a technical-review pathway before new work, while other programmes focus on permits, inspection and submission after completion. Read the current official instructions before signing a contract.
Owner handover
Flood Ready can support the project record.
A private contractor can provide assessment, quote, invoices, product information, photographs and installation documents within the agreed scope. The municipality or region controls eligibility, approval and payment.
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.

Important scope and homeowner questions.
Is BackwaterValves.ca part of a municipality?
No. It is a private service and information website.
Can you guarantee a rebate?
No. The programme administrator alone decides eligibility, approval and payment.
Should I choose an exterior valve because Markham lists one?
Only after property assessment. Programme categories do not establish technical suitability.
Why is an exterior valve not promoted for Halton subsidy?
Halton’s current contractor guide states that exterior backwater-valve installations are not eligible.
