The client
A Belleville applicant contributed $12,000 to an RRSP specifically to withdraw it back out days later under the Home Buyers' Plan, intending to use part of the enlarged withdrawal to pay down a $9,500 unsecured balance before closing.

The problem
An HBP withdrawal of contributed RRSP funds is genuinely tax-free — that much worked exactly as planned. What the applicant missed is the Income Tax Act's 89-day rule: any RRSP contribution made in the 89 days immediately before an HBP withdrawal from that same RRSP is not deductible for any tax year at all, even though the withdrawal itself proceeds normally.
What still worked, and what didn't
- ▸The withdrawal itself: fully valid and tax-free under the Home Buyers' Plan, exactly as expected
- ▸The $9,500 debt payout: funded successfully from the withdrawal, as planned
- ▸The deduction the applicant assumed came with the $12,000 contribution: denied outright by the 89-day rule, for any tax year
Nothing about the withdrawal or the debt payout went wrong. The tax-planning benefit the applicant had been counting alongside them simply never existed.
The numbers
The purchase itself qualified comfortably; the 89-day rule affected only the applicant's expected tax outcome, not the mortgage math.
| Qualifying the purchase | Amount |
|---|---|
| Total insured mortgage (incl. 3.10% CMHC premium) | $320,126 |
| Payment at the qualifying rate (6.95%), 25 years | $2,232/mo |
| Ontario land transfer tax on $345,000 | $3,650 |
| Total debt service | Figure |
|---|---|
| Property tax | $285/mo |
| Heat (lender estimate) | $110/mo |
| Car loan | $205/mo |
| Total debt service | 37.8% |
35.0% GDS and 37.8% TDS both sit inside CMHC's maximums, consistent with the range household debt-service ratios typically run across Canada, once the $9,500 balance was cleared using the withdrawal. The ratios were never at risk — the 89-day rule affected next year's tax return, not this file's approval.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act flagged the tax-planning mismatch before it became a surprise at filing time.
First, confirmed the exact contribution and withdrawal dates, and checked them directly against the Income Tax Act's 89-day window rather than assuming the deduction would simply follow the withdrawal.
Second, confirmed with the applicant's accountant that the $12,000 contribution would generate no deduction on any return, so expectations were corrected before, not after, filing.
Third, proceeded with the withdrawal and the $9,500 debt payout exactly as planned, since neither of those was ever affected by the 89-day rule — only the deduction was.
The outcome
The purchase funded insured at 35.0% GDS and 37.8% TDS, with the debt cleared as planned.
The applicant's expectations for next year's tax return were corrected before filing, not after — the only real cost of the 89-day rule on this file was a lost deduction, not a lost withdrawal.
What to take from this file
- 01A contribution made within 89 days of an HBP withdrawal from the same RRSP is not deductible, ever. The withdrawal itself remains valid and tax-free — only the deduction is lost.
- 02Don't assume a fresh RRSP contribution automatically buys a tax deduction just because it's followed by a valid withdrawal. Check the dates against the 89-day rule first.
- 03Route the deduction question to the client's own accountant before the client counts on it. A mortgage file can proceed correctly even while a tax-planning assumption underneath it is wrong.
- 04This is a different HBP trap from a repayment shortfall being mistaken for a debt. Here the withdrawal and repayment mechanics are both fine — it's the contribution's own deductibility that fails.
