Financing & Closing
Mortgage Requirements for Poly B: What Lenders Actually Look At
Poly B can come up during financing, not just insurance. Here's what lenders specifically tend to flag, and how a firm quote helps move a closing forward.
If a lender flags Poly B during your financing window, the clock is often tighter than the rest of the purchase — get a quote early.

Lenders vs Insurers
Lenders Aren't the Same as Insurers, but They're Related
Poly B can show up in two separate places during a home purchase: your insurer's underwriting, and your lender's financing conditions. They're related — most mortgages require proof of insurance to close — but a lender's specific concerns aren't identical to an insurer's.
A lender is generally focused on the property as collateral and on whether financing conditions (including proof of insurability) will be satisfied by closing day, not on pricing ongoing risk the way an insurer does.
What Gets Flagged
What Typically Gets Flagged During Financing
If a home inspection surfaces Poly B, a lender may ask for evidence that insurance is in place or obtainable before releasing financing — which loops back to whether your insurer will write a policy on a home with known Poly B in the first place.
Some lenders will accept a firm quote or a plan for replacement as sufficient, rather than requiring the work be completed before closing — but this varies by lender and by deal, so it's worth confirming directly with your mortgage broker rather than assuming.
How a Quote Helps
Why a Firm Quote Helps Move Things Forward
A rough inspection-report estimate doesn't carry the same weight as an actual on-site assessment and written quote — it's the difference between a guess and a real number your broker or lender can work with as part of satisfying a financing condition.

Provincial Variation
Requirements Vary by Lender and Province
Mortgage and insurance requirements aren't uniform across Canada — practices can differ by province and even by individual lender's internal risk policies, which is part of why we can't give a single universal answer here. Your mortgage broker, working directly with your specific lender, is the authority on what applies to your deal.
What stays consistent regardless of location is that a firm, on-site quote is more useful to a lender than a rough estimate, wherever you're buying.
If you're early in a home search and know Poly B is common in the era or neighbourhood you're looking at, it can be worth having this conversation with your mortgage broker proactively, before you're under a tight financing condition deadline on a specific property you've already made an offer on.
Common Questions
Frequently Asked Questions
Will my mortgage lender require Poly B replacement before closing?
It varies — some lenders accept a firm quote or plan rather than requiring the work done first. Confirm directly with your mortgage broker for your specific deal. Because these requirements aren't standardized across the industry, the same property could be treated somewhat differently by two different lenders, which is exactly why confirming directly with your own broker matters more than relying on general guidance alone.
Is a lender's concern the same as an insurer's?
Related but not identical — lenders generally care about financing conditions being satisfied by closing, including proof of insurance, which loops back to your insurer's own requirements.
Can you give me a quote before I close on a house?
Yes — we can do a referral to a licensed contractor before closing if you need a real number for a financing condition. We're glad to provide whatever documentation format your broker or lender specifically needs to satisfy their process.
Does a written quote carry more weight than an inspection estimate?
Yes — it's a firm number from an actual on-site visit, which lenders and brokers generally treat as more concrete than a rough inspection-report figure. We're glad to help however we practically can.
What should I ask my mortgage broker about Poly B?
Whether your specific lender requires replacement before closing, or will accept a quote or plan — this varies by lender and deal. We can also often turn around a written quote quickly enough to fit inside a typical financing condition window if your timeline is tight. We'll turn the quote around as quickly as your timeline needs.
Can you get a mortgage with Poly B?
Can you get a mortgage with Poly B - usually yes, though Poly B and mortgage approval can travel together in ways buyers do not expect. Mortgage requirements Poly B homes face arrive indirectly: the lender needs the property insured, so a lender Poly B condition often just mirrors what the insurer already said. A Poly B holdback closing arrangement, where funds are held back until the work is done, is one common way it gets resolved.
In Short
Mortgage Requirements for Poly B — The Short Version
Mortgage requirements for Poly B vary by lender, but the common thread is financing conditions tied to proof of insurance and, sometimes, evidence of a replacement plan. A firm, written quote from an on-site assessment carries more weight than an inspection estimate and can help satisfy a financing condition faster — confirm your specific lender's requirement with your mortgage broker. Because lender practices genuinely vary, treat any general guidance — including this page — as a starting point for the conversation with your specific broker, not a substitute for confirming your own deal's actual requirements directly with the people underwriting it. We're here whenever that timeline requires us. We keep that number honest regardless of your lender.
