Welcome to the first blog in my three-part series on powerful Canadian mortgage and tax strategies your bank would rather you didn’t know about. We’re starting with Rental Cash Damming—a strategy that helps landlords stop leaving money with the CRA and start turning everyday rental income into a smarter, tax-deductible plan. Think of this as your first step toward making your mortgage and rental properties work harder than you do.
If you own a rental property in Canada, let’s talk about one of the most underrated tax strategies out there: Rental Cash Damming. Sounds complicated, right? Like something your accountant mutters while they adjust their glasses. But here’s the truth—it’s actually one of the simplest, most powerful ways to stop leaving money on the table. And yes, that table is owned by the CRA.
What Is Rental Cash Damming?
Think of rental cash damming as rearranging your cash flow so that your mortgage interest becomes tax-deductible. Normally, you pay expenses on your rental property with rental income and then chip away at your personal mortgage with whatever’s left. But when structured correctly, your rental income goes toward paying down your non-deductible mortgage debt. Meanwhile, you use your HELOC (readvanceable mortgage) to cover the rental expenses. Suddenly, what used to be “just a mortgage payment” becomes part of a Canadian tax strategy that lets you deduct the interest against your rental income.
Why It Matters
Here’s the kicker: without cash damming, you’re handing the CRA more money every year than necessary. With it, you can:
- Convert non-deductible debt to deductible debt (magic words in the tax world).
- Claim deductible mortgage interest on your rental property.
- Improve cash flow and redirect more money toward building wealth.
In other words, your rental isn’t just paying for itself—it’s working overtime to help you build long-term wealth.
An Example (Keep It Simple)
Say you earn $2,000/month in rental income. Instead of using that money to cover property expenses, you use it to pay down your personal mortgage. Then, you draw $2,000 from your HELOC to pay the rental expenses. The result? Your debt shifts from non-deductible to deductible, and you now qualify to deduct that mortgage interest on your taxes. That’s real estate investing in Canada done smarter, not harder.
Why Haven’t You Heard of This?
Because banks love when you stick to the old way. It keeps you paying more interest for longer while they profit. Meanwhile, strategies like rental cash damming exist in plain sight—completely legal, completely CRA-approved.

If you own a rental property in Canada and you’re not using this strategy, you’re giving the CRA a tip every year. A big one. Stop leaving money on the table. Reach out and let’s talk about how to implement rental cash damming and make your mortgage interest tax-deductible.
