The client
A homeowner in the Rimouski market had a mortgage maturing with Bank A, and a competing offer from Bank B was on the table at a meaningfully better rate — one of the many renewal decisions counted in the Canadian mortgage renewal statistics. The file was a textbook candidate for a straight switch — provided nothing about the loan's amortization or balance changed on the way.

The exact request that would break the exemption
The two conditions a straight switch has to meet, both satisfied here as the file was originally structured:
| Exemption condition | This file |
|---|---|
| No increase in the remaining loan amount | Yes — $268,000 unchanged |
| No increase in the remaining amortization | Yes — 20 years unchanged |
| Federally regulated lender to federally regulated lender | Yes |
The problem
Before the paperwork was finalized, the client mentioned wanting to add $5,000 to the new mortgage to cover a kitchen renovation — a small, ordinary request, and one that would have quietly forfeited the entire benefit of the switch.
Why even a small top-up matters
- ▸OSFI's exemption for uninsured straight switches applies only when the loan amount and amortization do not increase at all
- ▸A $5,000 top-up raises the balance to $273,000 — any increase, not just a large one, forfeits the exemption
- ▸Without the exemption, Bank B would have had to qualify the file at the 7.09% minimum qualifying rate instead of the actual 5.09% rate
The client's request was reasonable on its own terms — a small renovation top-up is exactly the kind of thing a mortgage is supposed to help fund — but bundling it into this particular switch would have cost far more in qualification difficulty than the $5,000 itself was worth.
The numbers
Structured cleanly, the switch qualifies at the actual rate; topped up even slightly, it qualifies at the minimum rate instead.
| The clean switch, as actually structured | Amount |
|---|---|
| Payment renewing with Bank A at 5.64% | $1,855 |
| Payment switching to Bank B at 5.09% | $1,774 |
| Monthly savings | $81 |
| Savings over the 5-year term | $4,860 |
Because neither the loan amount nor the amortization increases, and both lenders are federally regulated, Bank B qualifies the file at the actual 5.09% rate rather than the 7.09% minimum qualifying rate that would otherwise apply.
What the $5,000 top-up would have changed
| With the $5,000 top-up (balance $273,000) | Figure |
|---|---|
| Qualifying payment at Bank B's actual 5.09% rate, had the exemption still applied | $1,807 |
| Actual qualifying payment required, exemption forfeited, at the 7.09% minimum rate | $2,115 |
The $5,000 the client wanted is a rounding error against the $268,000 balance, but it is not the size of the top-up that matters to the exemption — it is the fact of an increase at all. Once forfeited, the file would have needed to qualify at $2,115/month instead of the $1,774/month the clean switch actually required.
The solution
A courtier hypothécaire (mortgage broker) licensed by the AMF walked the client through exactly why the renovation request had to be handled separately from the switch itself, rather than folded into the new mortgage.
The switch was kept deliberately clean, with the renovation addressed through a separate product instead:
Once the client saw the actual numbers — a switch that qualifies easily at 5.09% versus one that would need to qualify at 7.09% over a $5,000 request — the renovation was financed separately, and the switch went through exactly as structured.
The outcome
Approved and funded: $268,000 straight switch to Bank B at 5.09%, 20-year remaining amortization unchanged, qualifying at the actual rate under the OSFI exemption.
As a switch rather than a purchase, no property transfer tax applies; the renovation was financed separately and did not touch the mortgage balance or its qualification path.
What to take from this file
- 01The exemption's conditions are binary, not a matter of degree. A $5,000 increase forfeits it exactly as completely as a $50,000 increase would.
- 02Ask about top-ups and amortization changes before structuring a switch, not after. A client's small, reasonable request nearly cost the entire benefit of the exemption.
- 03Keep unrelated financing needs out of a straight switch. A separate product for the renovation preserved both the switch's savings and the client's ability to fund the kitchen.
- 04Show the client the cost of the alternative in dollars. A $2,115 qualifying payment against a $1,774 one made the trade-off concrete rather than abstract.
