How the Strategy Works
There's a lesser-known strategy that combines two pieces of the tax code — the deductibility of investment loan interest, and the taxability of RRSP withdrawals — to potentially pull money out of your RRSP with little or no tax owing, while building a second, leveraged investment portfolio at the same time. Financial planners often call it the RRSP Meltdown strategy.
It's more advanced than most tax-planning conversations, and it comes with real risk. Here's how it actually works.
The Two Building Blocks
Borrow to Invest
Interest is deductible when borrowed money is used to earn income from a business or property — dividends, interest, or other income from a taxable, non-registered investment account.
RRSP Withdrawals
Money you take out of your RRSP is added to your taxable income for the year (outside specific programs like the Home Buyers' Plan).
Neither piece is unusual on its own — the strategy comes from lining them up on purpose.
Putting Them Together
- You borrow against home equity and invest the proceeds in a non-registered account.
- You deduct the loan interest each year, as normal.
- You withdraw an amount from your RRSP roughly equal to that year's deductible interest.
- The RRSP withdrawal adds to your taxable income; the interest deduction reduces it by a similar amount — so the two largely offset, and you owe little or no additional tax on the withdrawal.
Done over several years, this gradually "melts down" the RRSP — moving funds out of a registered account (where they'd eventually be taxed anyway, often at a worse time, like a large lump sum or at death) while simultaneously building a leveraged, non-registered portfolio funded by the borrowed money.
💡 Why People Use It
Smooths out RRSP taxation by spreading withdrawals across years instead of one large hit later. Builds a second portfolio alongside whatever's left in the RRSP. Useful heading into retirement, where required RRIF minimum withdrawals would otherwise push someone into a higher bracket.
The Real Risks — and They're Significant
This strategy leans on leverage, and leverage cuts both ways:
- You're borrowing to invest. If the non-registered portfolio drops in value, you still owe the full loan — the deduction doesn't protect the principal.
- Your home secures the debt. A HELOC or readvanceable mortgage is registered against your house.
- The offset isn't automatic or guaranteed. Interest rates float, and matching deductible interest precisely to a withdrawal that fully offsets the tax owed takes careful planning — done poorly, you can end up with taxable income and a smaller deduction than expected.
- Two risks stacked together. Market risk on the leveraged portfolio, plus using up RRSP tax-deferred room that isn't easily replaced once withdrawn.
- CRA scrutiny on deductibility. The loan needs to be clearly and traceably used for income-producing, non-registered investments to hold up the interest deduction.
⚠️ This isn't a set-and-forget strategy
It depends on your income, risk tolerance, home equity, time horizon, and disciplined year-by-year tracking of the loan and withdrawals. Done poorly, it adds leverage risk without the tax benefit lining up.
Bottom Line
Done well, the RRSP Meltdown can meaningfully reduce lifetime tax on RRSP funds. If this is something you're considering, it's worth reviewing your specific numbers with a professional before restructuring your mortgage or making RRSP withdrawals against it.
