The client
A household in Hawkesbury held a $260,000 variable-rate mortgage at maturity, switching to a new lender.
Mortgage balance
$260,000
At maturity, unchanged amortization
Discharge statement's rate used
6.45%
Stale -- from before the mortgage's most recent adjustment
Mortgage's actual effective rate
5.95%
In effect since the last rate change
Combined income
$8,400/month
The problem
A variable-rate mortgage's interest accrual is supposed to track the rate actually in effect at any given time. The outgoing lender's own discharge statement, prepared for this switch, instead accrued interest at 6.45% -- the rate that applied before the mortgage's most recent variable-rate adjustment, not the 5.95% that had actually been in effect since.
What the mismatch actually meant
- ▸At 6.45%, the discharge statement's monthly interest accrual came to $1,398
- ▸At the mortgage's true 5.95% rate, the correct monthly accrual was $1,289
- ▸The $109/month gap meant the payout figure used to size the new mortgage was overstated, however slightly, by a rate the mortgage itself was no longer actually charging
Nobody disputed the mortgage's own rate-change history. The discharge statement simply hadn't caught up to it.
The numbers
Once the correct rate was confirmed, qualifying the switch on the unchanged balance was ordinary arithmetic.
| Stale rate vs. actual rate | Amount |
|---|---|
| Monthly interest at the stale 6.45% | $1,398 |
| Monthly interest at the actual 5.95% | $1,289 |
| Gap the discharge statement needed correcting | $109 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (6.65%), 21 years remaining | $1,903/mo |
| Property tax + heat | $465/mo |
| Total debt service, switch to the new lender | 31.2% |
31.2% is informational -- this is an uninsured switch, so CMHC's ratio maximums do not apply directly, and the file was fully requalified at the minimum qualifying rate rather than relying on any switch exemption. Rate discrepancies like this one are exactly the kind of gap stress-test qualifying rate history is meant to guard against -- a payout figure has to reflect the rate actually charged, not a rate left over from before an adjustment.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the discharge statement as a figure to verify against the mortgage's own history, not a number to accept at face value.
First, pulled the mortgage's own rate-change notice history from the outgoing lender, confirming exactly when the variable rate had last adjusted and to what.
Second, recalculated the per-diem and monthly interest accrual at the mortgage's true 5.95% rate, comparing it directly against the discharge statement's stale 6.45% figure.
Third, put the $109/month discrepancy to the outgoing lender in writing and had the discharge statement reissued at the correct rate before releasing funds for the switch.
The outcome
The outgoing lender reissued the discharge statement at the mortgage's actual 5.95% rate, and the switch closed at 4.65%, with total debt service settling at 31.2%.
Because this file is uninsured, CMHC's ratio maximums do not apply directly; the 31.2% figure is informational, and the switch was fully requalified at the minimum qualifying rate rather than treated as exempt from it.
What to take from this file
- 01A discharge statement's own interest accrual can lag a variable-rate mortgage's most recent adjustment. Check the rate the statement actually used against the mortgage's own rate-change history before accepting it.
- 02A stale-rate discrepancy is a process gap at one lender, not evidence of a universal practice. Each lender's own systems handle a mid-cycle rate adjustment differently.
- 03Put a discrepancy like this in writing and ask for a reissued statement, rather than closing on a figure that does not match the mortgage's own documented history.
- 04A full requalification at the minimum qualifying rate is the safer default for a switch unless a specific, currently available exemption clearly applies.

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.
- ▸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.
Illustrative in this file — lender-specific, not rules:
- ▸6.45% / 5.95% / 4.65% rates — rates move daily; none is a quote.
- ▸the stale-rate discrepancy itself — each lender's own systems handle a mid-cycle variable-rate adjustment differently; a discharge statement lagging behind an adjustment is a system/process gap at this one lender, not a universal practice.
