The client
A Windsor household's $290,000 mortgage is maturing after a 3-year term. Three years ago, the original loan was funded as a cash-back mortgage, paying the household $9,000 at closing in exchange for staying with that lender for a minimum period the fine print sets at five years from the original advance date -- not five years from any one term.

The problem
A straight rate comparison makes switching look easy: $137/mo cheaper at the competing lender's offer, on an identical $290,000 balance. What that comparison leaves out is the cash-back agreement's own minimum-period clause, which is tied to five years from the date the money was originally advanced -- not to the three-year term that happens to be ending now. Two years of that five-year clock are still running.
Why the maturing term didn't end the clawback
- ▸The original cash-back agreement's minimum period runs from the advance date, independent of how the mortgage's own term is structured
- ▸A 3-year term maturing does not automatically satisfy a 5-year minimum-period commitment made at the same closing
- ▸Switching lenders now, two years short of that minimum, triggers repayment of the full $9,000 cash back, not a prorated portion
Priced on the rate alone, the switch is a clear win. Priced against the $9,000 the household would owe back, the real question became how long they intended to stay in the home -- not just which lender quoted the better number.
The numbers
Whether the clawback made switching worthwhile came down entirely to how long the household planned to stay, a question that renewal-cohort data can frame but never answer for one specific household.
| Pricing the switch against the clawback | Amount |
|---|---|
| Mortgage payment, renewing at 5.60% | $1,902 |
| Mortgage payment, switching at 4.75% | $1,765 |
| Monthly saving from switching | $137/mo |
| Cash-back clawback owed if switching now | $9,000 |
| Months of saving needed to recover the clawback | 66 months |
| Total debt service on the switch | Figure |
|---|---|
| Minimum qualifying rate on 4.75% | 6.75% |
| Payment at the qualifying rate, 22 years | $2,095 |
| Property tax and heat | $435 |
| TDS (payment + tax + heat + car loan) ÷ $8,500 income | 33.2% |
At 33.2% total debt service, the switch was never going to be blocked on the ratios. The only real question was whether 66 months was an acceptable payback period for this specific household -- and that depends entirely on how long they plan to stay.
The solution
A mortgage agent licensed under Ontario’s Mortgage Brokerages, Lenders and Administrators Act read the original cash-back agreement's own minimum-period clause before quoting the switch as a clear win.
First, confirmed the clawback's exact terms directly with the original lender. The five-year minimum ran from the advance date, not the term, and the full $9,000 was owed if the mortgage left before that date -- not a prorated amount.
Second, compared the cash-back trade-off the way it should have been compared from the start: the $9,000 owed back against the $137/mo saving, not the rate alone. Sixty-six months to break even is a real number a household needs to weigh, not a footnote.
Third, had a direct conversation with the household about how long they actually planned to stay in the home. Only once that answer was clearly beyond the 66-month payback point did the switch make sense to recommend.
The outcome
The household switched anyway, paying the $9,000 clawback, because they confirmed they plan to stay well beyond the 66-month payback point. The $137/mo saving pays for itself and keeps paying for the remaining 22 years of amortization.
Because this is an uninsured renewal, CMHC's ratio maximums don't apply to it; the 33.2% TDS figure is informational, confirming the switch was never a ratio problem -- only a payback-period decision.
What to take from this file
- 01A cash-back clawback's minimum period can outlast the mortgage's own term. Check the clause against the advance date, not against when the current term happens to mature.
- 02Never quote a switch on rate alone when the original mortgage was a cash-back product. The clawback is a real, quantifiable cost that changes the decision.
- 03Turn the clawback into a payback period, not just a warning. A specific number of months to break even lets a household make their own informed call.
- 04How long a household plans to stay is the actual variable that decides this kind of file. The math is the same either way; the right answer depends entirely on their own plans.
- 05A clawback isn't automatically a reason to stay put. A long enough time horizon can make paying it back and switching anyway the better outcome.

Illustrative in this file — lender-specific, not rules:
- ▸5.60% / 4.75% rates — rates move daily; neither is a quote.
- ▸the 5-year minimum-period clawback clause — each lender's cash-back program sets its own minimum relationship period and clawback terms -- not every cash-back mortgage works this way, and the exact clause has to be read on every file, not assumed.
- ▸the TDS figure — this file is uninsured, so there is no CMHC ratio ceiling -- the number is informational, not a pass/fail line.
