WealthInterest, Dividends and Capital Gains: Canadian Investment Tax Explained
The Three Types of Investment Income
In a non-registered (taxable) account, your investments can generate three main types of income:
- Interest: income from GICs, bonds, high-interest savings accounts (HISAs), and private loans.
- Dividends: distributions paid by corporations — either Canadian eligible dividends or foreign dividends.
- Capital gains: the profit you realize when you sell an investment (stocks, ETFs, real estate, etc.) for more than your adjusted cost base (ACB).
Each category is treated differently by the Canada Revenue Agency (CRA). Here is how they stack up.
Interest Income: The Least Tax-Efficient Option
Interest income is taxed at your full marginal tax rate — the same as employment income. If your combined federal-provincial marginal rate is 40%, every dollar of interest costs you 40 cents in tax.
This is why interest-bearing investments (GICs, bonds, HISAs) are generally the best candidates to shelter in a registered account like an RRSP or TFSA, where growth is sheltered from tax. See our article on how investment income is taxed in Canada for a broader breakdown.
Canadian Eligible Dividends: The Dividend Tax Credit Advantage
Dividends paid by Canadian public corporations are generally considered eligible dividends and benefit from the dividend tax credit — a mechanism designed to prevent double taxation (since the corporation already paid corporate tax before distributing profits). Here is how it works:
- You receive a dividend — say, $100.
- You must gross it up by a percentage set by the CRA to arrive at the grossed-up dividend amount.
- The grossed-up amount is added to your taxable income.
- You then apply the dividend tax credit (federal + provincial) directly against your tax owing.
The net result: at equivalent dollar amounts, an eligible Canadian dividend is generally taxed at a lower effective rate than interest income. The exact rate varies by province and your total income — always confirm current figures with the CRA or a tax professional. Our article on the Canadian dividend tax credit explains the mechanics in detail.
Lean Canadian eligible dividends
- Paid by Canadian public corporations
- Benefit from the dividend tax credit, which prevents double taxation
- Generally taxed at a lower effective rate than interest at equivalent income levels
- Best held in a non-registered account, where the tax advantage is fully realized
Lean foreign dividends
- Paid by foreign corporations (U.S., European firms, etc.)
- NOT eligible for the Canadian dividend tax credit
- Taxed like interest income, at your full marginal rate
- Often subject to foreign withholding tax at source (e.g., 15% for Canadians receiving U.S. dividends)
- Better suited for a registered account like an RRSP, where U.S. withholding is exempt
Not all dividends are equal at tax time — where they come from changes everything.
Foreign Dividends: A Different Story
Dividends paid by foreign corporations (U.S. companies, European firms, etc.) are not eligible for the Canadian dividend tax credit. They are taxed like interest income — at your full marginal rate. Additionally, withholding tax is often deducted at source by the foreign country (e.g., 15% for Canadians receiving U.S. dividends). While a foreign tax credit may apply, foreign dividends remain less tax-efficient than Canadian eligible dividends in a non-registered account.
Capital Gains: The Most Tax-Efficient Investment Income
Capital gains are the most tax-favoured type of investment income under Canadian law, for two key reasons:
- Partial inclusion: only a portion of your capital gain is included in taxable income. Under the current inclusion rate, roughly half is taxable — meaning a $10,000 gain may add only $5,000 to your income. Verify the current inclusion rate with the CRA, as it has been subject to proposed changes in recent federal budgets.
- You control the timing: a capital gain is only taxable when you sell. As long as you hold the investment, no tax is triggered — your growth compounds on a tax-deferred basis.
For more detail, see our article on capital gains tax in Canada explained.
Comparison Table: Tax Efficiency by Income Type
| Income Type | Tax Treatment | Tax Efficiency | Best Account |
|---|---|---|---|
| Interest (GICs, bonds, HISAs) | 100% taxable at marginal rate | Least efficient | RRSP / TFSA |
| Foreign dividends | 100% taxable + possible foreign withholding | Low efficiency | RRSP (U.S. withholding exempt) |
| Canadian eligible dividends | Grossed up + dividend tax credit applied | Moderately efficient | Non-registered account |
| Capital gains | ~50% taxable; timing controlled by investor | Most efficient | Non-registered account |
In your RRSP or TFSA
- Prioritize interest-bearing investments (bonds, GICs, HISAs)
- Prioritize foreign dividend-paying investments
- Their unfavourable tax treatment in non-registered accounts is avoided entirely
In your non-registered account
- Favour Canadian dividend-paying stocks
- Favour growth-oriented investments whose capital gains you can defer and control
- Asset location does not change your gross returns — it just reduces how much of those returns go to the CRA
Same portfolio, different tax bill — depending on which account holds what.
The Practical Takeaway: Asset Location
This tax difference leads directly to the concept of asset location: strategically placing each type of investment in the account where its tax treatment is most advantageous.
- In your RRSP or TFSA: prioritize interest-bearing investments (bonds, GICs, HISAs) and foreign dividend-paying investments. Their unfavourable tax treatment in non-registered accounts is avoided entirely.
- In your non-registered account: favour Canadian dividend-paying stocks and growth-oriented investments whose capital gains you can defer and control.
Asset location does not change your gross returns — it just reduces how much of those returns go to the CRA. Our article on asset location in Canada walks through practical examples.

Frequently asked questions
What is the most tax-efficient type of investment income in Canada?
Capital gains are generally the most tax-efficient: only a portion of the gain (roughly 50% under the current inclusion rate — confirm with the CRA) is taxable, and you control when you trigger the gain by choosing when to sell. Canadian eligible dividends come second, thanks to the dividend tax credit. Interest income is least efficient, taxed at 100% of your marginal rate.
Are dividends always taxed less than interest in Canada?
Not always. Canadian eligible dividends are generally taxed at a lower effective rate than interest at equivalent income levels, thanks to the dividend tax credit. However, the exact comparison depends on your province, total income, and marginal rate. A tax professional can calculate the exact impact for your situation.
Are U.S. dividends (e.g., from S&P 500 ETFs) eligible for the Canadian dividend tax credit?
No. Dividends from foreign corporations, including U.S. companies, are not eligible for the Canadian dividend tax credit. They are taxed as ordinary income at your full marginal rate. A 15% U.S. withholding tax also applies for most Canadians (though a foreign tax credit may offset some of this). This makes U.S. dividend-paying investments better suited for registered accounts like an RRSP.
What is asset location and why does it matter?
Asset location is the strategy of placing different types of investments in different account types based on their tax treatment. The goal is to shelter the least tax-efficient income (like interest and foreign dividends) inside registered accounts (RRSP, TFSA), while keeping the most tax-efficient income (Canadian dividends, capital gains) in non-registered accounts where their tax advantages are fully realized.
Is a capital gain taxed when the investment grows in value or when I sell?
Only when you sell (or otherwise dispose of) the investment. Until then, no capital gains tax applies — regardless of how much the value has increased. This deferral is one of the biggest advantages of growth-oriented investing: you decide when to trigger the tax event.
Do I need to report investment income from a non-registered account to the CRA?
Yes. All interest, dividends, and realized capital gains in a non-registered account must be reported on your annual tax return. Your broker or financial institution will issue tax slips (T5, T3, T5008) to help you report accurately. Keep records of your adjusted cost base (ACB) for any investments you hold.
