Disappearing-Source Continuation (ITA §20.1)
Section titled “Disappearing-Source Continuation (ITA §20.1)”Objective — keep deducting interest on investment debt that outlived the investment it funded, after the investment was sold at a loss.
Risk level — -1 — Negative risk.
Risk justification — the loss has already happened and the debt already exists; §20.1 preserves a deduction that general principles would otherwise remove. Nothing new is taken on.
Benefit justification — unverified — needs Talbot.
Jurisdiction — Canada. This provision has no U.S. analogue in this form; do not translate.
Prerequisites
Section titled “Prerequisites”Three statutory conditions (ITA §20.1):
- Borrowed money was used to acquire capital property other than real or depreciable property.
- The property is disposed of.
- The proceeds are used to repay part of the debt, and a balance remains.
Mechanism
Section titled “Mechanism”Where those conditions are met, the remaining debt — to the extent of the deficiency — is deemed to continue to be used for income-earning purposes, and interest on that deemed amount stays deductible.
Worked example from the source:
- Borrow $100,000 to buy shares.
- Shares decline; sold for $40,000.
- $40,000 applied to the loan; $60,000 remains.
- Under §20.1 the $60,000 is deemed used for income-earning purposes; interest on it continues to be deductible even though the investment is gone.
Benefits
Section titled “Benefits”Softens the after-tax cost of the exact scenario leveraged investors fear most — a loss sale leaving debt behind.
None added. The relief is conditional, and the condition is where it fails.
Failure modes
Section titled “Failure modes”- Spending the proceeds instead of applying them to the debt. §20.1 then does not apply to the full amount. This is the single condition that decides the outcome.
- Losing the tracing from original borrowing → investment → proceeds → repayment.
- Assuming it covers real or depreciable property. It does not.
None beyond record-keeping.
Tax considerations
Section titled “Tax considerations”ITA §20.1. Note the interaction with §7.2: interest that exceeds investment income becomes a non-capital loss, deductible against any income source, carried back 3 years or forward 20.
Who it may suit
Section titled “Who it may suit”Any leveraged investor who has sold at a loss with debt outstanding — the point at which this is most often not known.
Who should avoid it
Section titled “Who should avoid it”Nobody. It is relief, not a decision.
Implementation outline
Section titled “Implementation outline”- Before selling, confirm the property is capital property other than real or depreciable property.
- Apply the entire proceeds of disposition to the debt.
- Document the trace from borrowing to purchase to sale to repayment.
- Continue claiming interest on the remaining balance.
Evidence status
Section titled “Evidence status”external-sourced — ITA §20.1 with its statutory conditions and worked example, via Core/_WorkingOn/Research/canada-investment-taxation.md §6.4.
Counterarguments
Section titled “Counterarguments”- Framing a consolation provision as a “strategy” risks making leverage look safer than it is. Fair. The record’s tier is level -1 because claiming the relief is riskless; it says nothing about the leverage that produced the loss, which is level 2/level 3 and carries its own records.
Variants
Section titled “Variants”None.
