Waiting for More Equity Is a Quiet Bet That Ottawa Won't Raise Taxes
Ottawa closed its fiscal year on March 31, 2026 with an accumulated deficit of $1.322 trillion, according to the Department of Finance. That figure is the running total of every federal deficit and surplus since Confederation, and it keeps climbing. A government carrying that load has three ways to manage it: raise taxes, cut spending, or let inflation shrink the debt's real value. Two of those three land directly on a homeowner with a large mortgage.
This piece is about timing. If you have real equity, steady income and money you could invest, holding off on restructuring your mortgage is a decision with a cost. You keep paying interest the tax system gives you nothing back on, and you're quietly betting that the rules and rates you'd use later will look like the ones available today.
When waiting is the right call
The usual advice says to build more equity, let your income settle, and revisit advanced strategies in a few years. For plenty of households that's correct. If your income swings with contracts or commissions, if you'd sell investments in a panic during a bad year, or if you have no emergency fund, borrowing against your home to invest adds risk you don't need. Deductible debt is still debt. If line-of-credit rates jump, the after-tax cost can outrun what your investments earn.
The advice stops fitting the household that has already cleared those hurdles and is waiting anyway.
Deductions are worth more when taxes go up
Under CRA rules, interest on money borrowed to earn income from a business or property is generally deductible. The Smith Manoeuvre™ uses that rule. As you pay down principal on your mortgage, you reborrow the same amount through a line of credit and invest it. Your total debt stays about the same, but a growing share of it becomes deductible.
Here is illustrative arithmetic, not a forecast. Say you have $100,000 of converted debt at 5% interest, which is $5,000 a year. At a 40% marginal rate the deduction is worth $2,000. If your rate rises to 45%, the same interest is worth $2,250. Islanders already pay combined marginal rates among the highest in the country, close to half at the top bracket, so every point added matters more here than in most provinces.
Conversion happens gradually, one principal payment at a time. A household that starts in 2026 will have years of converted debt in place by the time any tax increase arrives. A household that starts later begins from zero.
The real scarce resource is qualifying
Equity matters less than people think. What matters is whether you can get the right mortgage. The strategy needs a readvanceable mortgage, which pairs a regular term mortgage with a line of credit, and you generally need at least 20% equity. OSFI caps the revolving line-of-credit portion at 65% of your home's value. You also have to qualify at the higher of your contract rate plus 2% or 5.25%, even though you'll pay your actual contract rate.
Every one of those conditions depends on your income and on rules set in Ottawa. A job change, a move to self-employment, or a tighter lending guideline can leave you holding plenty of equity you can't use. The households in the strongest position set up the structure while they qualify comfortably.
Three questions that settle it
Tax policy in Canada moves slowly, and nobody can promise that interest deductibility will be restricted, or that tax rates will rise. You don't need to know either way. Ask these instead:
Would you qualify for a readvanceable mortgage today at the stress-test rate, with the line staying under 65% of your home's value?
Could you carry the line of credit if its rate rose noticeably, without selling investments at a bad time?
Will you keep clean records showing every borrowed dollar went into income-producing investments? CRA expects that paper trail, and it isn't optional.
If any answer is no, waiting is the right choice, and you should spend the time fixing that answer. If all three are yes, then waiting is the bet described in the title, and it's worth putting the two paths side by side and running the numbers before you place it.
