The client
A homeowner in Moncton reached renewal with a $275,000 balance, 18 years of amortization remaining, and a late payment still fresh on the bureau from a rough stretch mid-mortgage — one data point inside a broader pattern of payment increases at renewal across Canada. The maturing lender’s renewal offer needed no new underwriting at all; a competing lender’s rate was materially better, but came with a full credit and income re-qualification.

The problem
Straight renewal with the maturing lender at 6.14% requires nothing new — no fresh credit pull, no re-underwriting, because the lender is simply extending the existing relationship.
A competing lender’s straight-switch offer at 5.19% is materially better on paper, but a switch is a new mortgage in the receiving lender’s eyes. It would be tested using the lender’s normal underwriting — including a fresh credit pull that would surface the recent late payment.
What each path costs, in the numbers
- ▸Staying: payment $2,095/mo, TDS 31.8% against $8,300/mo income — comfortably serviceable, no new underwriting.
- ▸Switching (if approved): payment $1,953/mo — $142/mo less — but only if the new lender’s credit adjudication clears the recent late payment.
The numbers
Because a switch with no increase in loan amount or amortization between two federally regulated lenders is exempt from OSFI’s minimum qualifying rate, the rate test itself was never the obstacle here — against the backdrop of renewal volume running high across the market.
| What the switch would and wouldn’t have to clear | Amount |
|---|---|
| Balance | $275,000 |
| Remaining amortization | 18 years |
| Stay rate (renewal, no new underwriting) | 6.14% |
| Switch rate (new lender, full re-qualification) | 5.19% |
| Path | Monthly payment | TDS |
|---|---|---|
| Stay with the current lender | $2,095 | 31.8% |
| Switch (if approved) | $1,953 | not tested at 44% — uninsured, informational only |
If this switch had to clear a fresh minimum qualifying rate, that rate would be 7.19% — but the exemption means the switch, if it proceeds, is tested at the 5.19% contract rate instead. That is not the risk in this file. The risk is that the new lender’s own credit-adjudication policy, applied to a fresh bureau pull, treats the recent late payment as a live reason to decline or attach conditions — a decision the exemption has no bearing on at all.
The solution
A mortgage associate licensed with New Brunswick’s FCNB laid out both paths for the client in plain terms: staying protects against a live decline this renewal cycle; switching saves $142 a month, but only if the new lender’s credit review clears — and there was no way to know that for certain without applying and risking a hard pull and a possible decline on record, the kind of mid-application credit wrinkle our piece on disputed credit items mid-application covers, even though this one isn’t in dispute, just recent.
The recommendation was to renew with the current lender for this term, then revisit the switch in six months once the late payment ages further from the reporting window and more clean payment history sits on top of it.
The outcome
Renewed with the existing lender at 6.14%, no new underwriting, no risk to the file. The $142-a-month savings a switch might have delivered stayed on the table — a deliberate trade against the risk of a declined application landing on the bureau at the worst possible time.
This is a timing decision, not a permanent one. The plan on file is to re-test the switch at the next opportunity, once the credit picture has had longer to recover.
What to take from this file
- 01A straight renewal needs no new underwriting. Staying with the maturing lender is the lowest-risk path when credit has recently taken a hit.
- 02The MQR exemption removes the rate test, not the credit review. Even an exempt straight switch is still a new application at the new lender, subject to its own credit adjudication.
- 03Weigh the savings against the risk of a hard decline. $142 a month is real money, but a fresh decline on the bureau has its own cost.
- 04Time the next attempt. Recommending a specific window to revisit the switch turns a one-time decision into an ongoing plan for the client.
