Smart Refi(und): The RRSP Refund Loop
Use home equity to fund an RRSP contribution. The refund reduces your real cost. Investments grow tax-sheltered.
The Big Idea
Borrow against home equity → contribute to RRSP → receive tax refund → use the refund to reduce mortgage or reinvest. The refund conceptually lowers what the contribution truly cost you.
The Simple Math
Your refund is calculated using your marginal tax rate — the rate on your last dollar earned.

Understanding the Strategy:
- RRSP Contributions: Tax-deductible retirement savings that grow tax-deferred
- Tax Refunds: Immediate cash back based on your marginal tax rate
- CRA Requirements: Investments must produce income (dividends, interest, rent) for interest deductibility
- Risk Considerations: Leveraged investing amplifies both gains and losses
