Millions of Canadians are renewing mortgages that were locked in during the COVID era at historically low rates. Now, they are facing rates that are often double what they previously had, meaning significantly higher monthly payments each month.
The increase in interest rates has been unsettling, even for financially secure households, and it’s forcing many high-income earners to consider prioritizing mortgage repayments to reduce interest costs and become debt-free sooner.
At first glance, this feels like a disciplined and financially sound move. A higher mortgage rate can make prepayments seem like a “guaranteed return,” especially compared to uncertainty of markets.
But is that the best use of cash flow? That depends on your broader financial picture.
The benefits of paying down your mortgage faster
There are clear benefits to accelerating your mortgage payments and many high-income earners are focusing on these benefits when making their decision
❖ Higher interest savings:
The higher your rate, the more impactful each dollar toward your principal becomes.
❖ Risk reduction:
Reducing debt provides peace of mind. Watching your mortgage balance decline and knowing your largest asset is becoming debt-free faster, can feel really reassuring.
❖ Improved cash flow over time:
Once the mortgage is paid off, you free up cashflow to be used for other investments.
For many families, especially those approaching retirement, this can be a powerful strategy.
What you lose out on by allocating extra money to your mortgage
For high-income households, there are trade-offs that are made when you allocate capital to your mortgage.
❖ Lack of diversification
When a large portion of your net worth is tied up in your home, your financial position is concentrated in a single-asset, real estate. While real estate can be a strong long-term asset, it doesn’t provide the same diversification as a well-constructed investment portfolio.
In many cases, mortgage rates may be lower than long-term market returns, which means this approach can slow overall net worth growth and limit your ability to allocate capital towards potentially higher-return opportunities.
❖ Missed Tax Advantages
High-income earners are in the strongest position to benefit from registered accounts. RRSPs provide immediate tax deductions which is valuable at higher marginal tax returns and TFSAs offer tax-free growth and withdrawals, creating flexibility for future needs.
Redirecting cashflow towards your mortgage may mean underutilizing your registered accounts and increasing your tax burden.
❖ Liquidity Constraints
Home equity is not as easily accessible without refinancing or borrowing. When compared to investments that can be sold, paying down a mortgage converts liquid capital into home equity, which is harder to access quickly. A strategy that favours a mortgage can leave you house-rich and cash-poor.
❖ Opportunity Cost
Long-term investors need to consider the potential growth of invested capital. While markets fluctuate, disciplined investments over time can support long-term wealth accumulation. If you divert all surplus cash to debt repayment, you may be reducing or delaying your compounding investment growth.
A balanced approach
Don’t think about mortgage repayment as an either/or situation. A well-defined financial plan can help clarify not only what you’re gaining, but also what you are giving up, so that your decisions are made with confidence and intention.
If you are considering accelerating your mortgage, it’s worth asking yourself
❖ Am I maximizing my RRSP and TFSA opportunities?
❖ Do I have sufficient liquidity for emergencies and opportunities?
❖ How much of my net worth is tied to real estate?
❖ How will this decision affect my long-term retirement plan?
For high-income earners, the real opportunity lies in balancing debt reduction with tax-efficient investing and diversification.
