The client
A couple in the Medicine Hat market had owned the same house since 2007 and paid the mortgage down steadily. At this maturity they had $58,400 owing and six years of amortization left. They had read that renewal is the moment to shop — correct advice, and the reason roughly a fifth of Canadian mortgage holders now change lenders at maturity rather than sign the first offer, as the renewal data shows. It simply did not apply to them.

The problem
Three lenders were approached and all three quoted a rate. Rates are quoted off a sheet; eligibility is checked at submission, and that is where the file stopped. Every transfer program carries a minimum mortgage amount, and this balance sat under all of them. The figures vary by lender and by program — floors in the $50,000 to $100,000 range are common — but the important point is that a minimum mortgage amount is a lender’s own commercial policy, not a regulatory threshold. Nobody publishes it beside the rate.
Why a floor exists at all
- ▸A switch costs the incoming lender roughly the same to underwrite, instruct and register whether the balance is $58,000 or $580,000
- ▸The lender’s return is earned on the spread over the term, and on a small balance the spread does not cover the fixed cost of acquiring the file
- ▸Programs where the lender absorbs the legal and appraisal cost of the transfer are the ones with the highest floors, for the same reason
- ▸None of this is a credit decision, so there is nothing about the borrower to fix
That left the second question, which is the one worth teaching: even if a lender had taken the file, what was the move actually worth? Rate differences are quoted as percentages, which makes them feel scale-free. They are not. Fixed costs do not shrink with the balance, and neither does the effort.
The numbers
The honest comparison is not two rates. It is the total cash paid across the term plus the balance still owing at the end of it — the number that tells you what each path really costs to arrive at the same place.
Balance $58,400, six years of remaining amortization, three-year term. Rates of 5.49%, 4.79% and 4.99% are illustrative and not quotes.
| Stay: the 5.49% renewal offer | Amount |
|---|---|
| Monthly payment | $952 |
| Paid over 36 months | $34,272 |
| Balance still owing at the end of the term | $31,567 |
| Total cost of the path | $65,839 |
| Switch: the 4.79% quote, had it been accepted | Amount |
|---|---|
| Monthly payment | $934 |
| Paid over 36 months | $33,624 |
| Balance still owing at the end of the term | $31,270 |
| Total cost of the path | $64,894 |
| The difference | Amount |
|---|---|
| Total three-year saving from 0.70 percentage points | $945 |
What the negotiated rate was worth
Against $945, the discharge fee and any registration and legal cost not absorbed by a transfer program are not a rounding error. Alberta’s registration costs are modest but they are real, and on a balance this size they consume a meaningful share of the prize before anyone has saved a dollar. The alternative was to stop shopping and start negotiating.
| Renew at the negotiated 4.99% | Amount |
|---|---|
| Monthly payment | $939 |
| Paid over 36 months | $33,804 |
| Balance still owing at the end of the term | $31,355 |
| Total cost of the path | $65,159 |
| Saving against the original offer | $680 |
That is 72.0% of what the unreachable 4.79% would have been worth, obtained with no discharge, no new registration and no legal file.
The solution
A mortgage associate licensed by the Real Estate Council of Alberta under the Real Estate Act, RSA 2000, c. R-5, resisted the instinct to keep submitting the file and priced the decision instead.
First, read the renewal statement properly before quoting anything: the exact maturity date, the balance at maturity rather than today’s balance, and the remaining amortization. On a six-year remaining term the payment is dominated by principal, which is precisely why the rate matters less than the client expected.
Second, asked each lender for its minimum mortgage amount in writing rather than submitting and waiting. Two answered in a day. Screening on eligibility before packaging a file is the cheapest step available, and it is the step most often skipped — the sequencing is set out in our switch and transfer underwriting guide.
Third, went back to the incumbent with the three written quotes and the total-cost table, not with a rate demand. A retention desk can price against evidence; it cannot price against an assertion.
The outcome
The mortgage renewed with the incumbent at 4.99% for three years: $680 better than the first offer, roughly seventy per cent of a saving that was never actually available, and achieved with no discharge, no new registration and no legal work at all. The client had also been shown, in writing, exactly why they were not switching — which is a different outcome from simply signing the offer that arrived.
What to take from this file
- 01A quoted rate is not an eligible rate. Every transfer program has a minimum mortgage amount set by the lender, not by regulation, and it is checked at submission rather than at quote.
- 02Ask for the floor before you package the file. One email per lender costs nothing and saves a small-balance client the fortnight this file lost.
- 03Compare total cost over the term, not rates. Cash paid plus the balance still owing at the end is the only comparison that survives different amortizations, and it shrinks a headline gap to its real size.
- 04On a small balance, the fixed costs are the whole argument. Legal, registration and discharge costs do not scale down with the mortgage, so the break-even moves against switching as the balance falls.

- ▸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:
- ▸5.49% renewal offer, 4.79% best competing quote and the 4.99% negotiated outcome — rates move daily; none of these is a quote.
- ▸minimum mortgage amounts in the $50,000 to $100,000 range — each lender sets its own floor per program; this is commercial policy, not a regulatory threshold.
- ▸a six-year remaining amortization on a three-year term — a scenario input, chosen to show how a short remaining amortization mutes a rate difference.
