The client
A homeowner in Pembroke switched a $258,000 mortgage at maturity, with 21 years remaining amortization, to a new lender at 4.65%.
Balance at maturity
$258,000
21 years remaining amortization
Non-renewal notice
Issued for roof age
Months before maturity, mistaken for routine paperwork
Combined income
$7,200/month
Other debt
$230/mo car loan
The problem
An insurer that declines to renew a policy -- here, for roof age approaching the end of its expected service life -- mails a non-renewal notice well ahead of the term's actual end. That notice looks, at a glance, exactly like a routine annual renewal package.
What the homeowner missed
- ▸The non-renewal notice arrived months before the policy's own term end, alongside the mortgage's own separate maturity date
- ▸The homeowner assumed it was standard renewal paperwork and set it aside
- ▸The home sat with no active insurance policy at all for roughly 4 months before anyone caught it
Nothing was wrong with the switch itself. The home simply had not been insured for months, and nobody had noticed until the new lender's solicitor asked.
The numbers
Once continuous coverage was back in place, the switch itself was straightforward.
| The straight switch, once insured | Amount |
|---|---|
| Mortgage balance at maturity | $258,000 |
| Total debt service | Figure |
|---|---|
| Payment at 4.65%, 21 years remaining | $1,599/mo |
| Property tax | $295/mo |
| Heat (lender estimate) | $115/mo |
| Car loan | $230/mo |
| Total debt service | 31.1% |
31.1% is informational on this uninsured straight switch -- there is no CMHC ceiling to clear. Renewal timing generally is a starved topic for brokers to get right; Canadian mortgage renewal statistics show how much volume moves through this exact window every year. The ratio was never the risk on this file -- the four uninsured months were.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the proof-of-insurance request as a real closing condition, not a formality to confirm after the fact.
First, when the request for a current binder came back with nothing, traced the timeline back to the non-renewal notice the homeowner had kept but never actioned, confirming the roof-age reason and the exact date coverage had actually lapsed.
Second, arranged emergency coverage through an insurer willing to bind immediately, appropriate to the roof's actual age, at a modestly higher premium than the lapsed policy -- with no attempt to backdate anything.
Third, supplied the new binder to the new lender's solicitor before scheduling the switch's own closing as a switch, not a refinance, since the balance and amortization were unchanged.
The outcome
The switch closed at 4.65% once continuous, current proof of insurance was in the lender's hands, with total debt service at 31.1%.
Because this file is an uninsured straight switch, CMHC's ratio maximums do not apply directly; the 31.1% figure is informational, showing the switch itself was never the risk on this file.
What to take from this file
- 01A non-renewal notice does not look like an emergency, but it is one. Coach clients to open every piece of insurer mail near a policy's term end, not just near the mortgage's own maturity date.
- 02A mortgage's maturity date and a home policy's own term end are two separate clocks. One can lapse quietly while the other approaches on schedule.
- 03Ask for proof of insurance early in a switch, not at the closing table. A gap found with weeks of runway is a fixable problem; the same gap found the week of closing is a crisis.
- 04An emergency binder is usually available, at a price. An insurer willing to bind on short notice for a specific, known issue (like roof age) is the practical fix once a lapse is found.

- ▸OSFI — Minimum qualifying rate for uninsured mortgages — the minimum qualifying rate — greater of contract rate + 2% or 5.25%.
- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
- ▸OSFI — OSFI exempts uninsured mortgage straight switches from the prescribed MQR and implements portfolio LTI limits — MQR exemption for uninsured straight switches at renewal (from Nov 21, 2024).
Illustrative in this file — lender-specific, not rules:
- ▸4.65% switch rate — rates move daily; not a quote.
- ▸the roof-age non-renewal and the emergency binder's premium — each insurer sets its own roof-age underwriting threshold and its own price for binding on short notice; neither is a published rule.
- ▸the TDS figure — this file is an uninsured straight switch, so there is no CMHC ratio ceiling -- the number is informational.
