Buy Borrow Die Strategy Canada: How It Works and What the CRA Can Actually Do

You hold appreciating assets, typically publicly traded securities, private company shares, or real property, inside a holding company or personally, and borrow against them using a portfolio margin loan or a Lombard-style facility from a Canadian chartered bank. The loan proceeds are cash and therefore not income, so no tax is triggered on access to liquidity. The asset continues to compound unrealized. On death, the deemed disposition rules under the Income Tax Act do trigger a capital gains inclusion, but strategic use of the principal residence exemption, spousal rollovers, and life insurance can offset or defer that final bill almost entirely.

RBC Dominion Securities, TD Wealth, and BMO Nesbitt Burns all offer securities-backed lending, typically at 50 to 70 percent loan-to-value on a diversified equity portfolio, with rates currently floating around prime plus 0.5 to 1.5 percent depending on portfolio size and relationship. Private banking thresholds generally start at CAD 1 million in investable assets for a dedicated credit facility, though some private bank desks engage meaningfully at CAD 3 million and above. For larger structures, National Bank and CIBC Private Wealth also compete aggressively. The interest on these loans is not deductible if the proceeds are used for personal consumption, which is a critical structural point that separates a clean Canadian implementation from a sloppy one. Lombard loan vs SBLOC breaks down the facility structures in detail if you are deciding between pledge-based and margin-based setups.

Most serious Canadian implementations run the asset accumulation phase through a Canadian Controlled Private Corporation, not personally. The CCPC pays a lower corporate tax rate on investment income (roughly 50 percent in most provinces on passive income, but active business income gets the small business deduction down to around 12.2 percent in Ontario), and retained earnings inside the corporation compound without being immediately taxed in the hands of the shareholder. The shareholder then borrows against the shares of the holdco rather than the underlying portfolio directly, adding a layer between the lender and the assets. On death, the lifetime capital gains exemption of CAD 1,016,602 (2024 figure, indexed annually) can shelter gains on qualifying small business corporation shares, which is a feature unavailable on passive portfolios held personally.

The CRA's primary weapon against borrow-to-consume structures is the interest deductibility denial under section 20(1)(c) of the Income Tax Act. If loan proceeds fund personal consumption rather than income-earning investments, the interest is not deductible and the structure loses one of its main advantages. The General Anti-Avoidance Rule (GAAR) is the bigger threat: the 2024 amendments strengthened GAAR significantly, lowering the threshold for what constitutes an avoidance transaction and introducing a 25 percent penalty on GAAR-assessed benefits. However, GAAR requires that the transaction frustrate the object and spirit of the Act, and straightforward borrowing against a portfolio to fund reinvestment has decades of clean precedent. The CRA cannot force you to sell assets to pay a tax bill on unrealized gains, which is the foundational legal reality the entire strategy rests on.

Unlike the US, Canada has no step-up in cost basis at death. The deemed disposition rule treats the deceased as having sold every asset at fair market value the moment before death, triggering capital gains on the full unrealized appreciation. The three main neutralization tools are: a spousal rollover that defers the entire deemed disposition until the surviving spouse's death, a permanent life insurance policy sized to cover the projected tax liability (held inside the estate or a holding company to keep proceeds creditor-protected and tax-free), and charitable bequests that generate donation credits offsetting the terminal return. A well-structured estate using all three can reduce the effective capital gains tax on death to near zero even without any offshore component.

For Canadians with assets above roughly CAD 5 to 10 million, layering in a Barbados holding company or a Luxembourg structure can shelter foreign-source income from Canadian corporate tax via treaty, since Canada's tax treaty network is extensive and the foreign affiliate rules in the Income Tax Act specifically contemplate offshore holding structures. Barbados-Canada treaty benefits have survived multiple CRA challenges because the foreign affiliate regime under sections 90 to 95 of the Act explicitly permits them when properly structured. The compliance cost is real: foreign affiliate reporting (T1134), foreign income verification (T1135), and legal fees for proper setup run CAD 15,000 to 40,000 in year one and CAD 8,000 to 20,000 annually to maintain. Below the CAD 5 million threshold, this overhead typically eats the tax savings and the structure does not pencil out.
