Corporate Investment in Mortgages in Canada: Investing Through a Corporation or Holding Company

Many Canadian business owners accumulate cash inside a corporation — an operating company with retained earnings, or a holding company that receives dividends from one. The question that follows is whether that money can be invested in mortgages without first paying it out and paying personal tax on it. The short answer is that corporate investment in mortgages in Canada is generally possible; the longer answer is that the tax result, the eligibility rules and the paperwork all differ from investing personally, and the differences cut both ways.

Owners whose companies hold surplus cash not needed in the business for several years might consider the route, alongside the alternatives. This page explains the mechanics as at October 2026. It is general education, not investment, tax or legal advice; corporate tax is fact-specific, and a Canadian tax professional can apply it to your company. Mortgage investments are not guaranteed. Returns are targets, not promises, and principal can be lost.

Can I invest in mortgages through my corporation?

Generally, yes. A corporation can subscribe for shares of a mortgage investment corporation (MIC), or hold a mortgage directly, provided it has the authority to make the investment and qualifies under a prospectus exemption for the securities it buys.

In practice, the common route is MIC shares. The corporation is the subscriber: the shares are registered in its name, the distributions are paid to its bank account, and the tax slip is issued to it. Three things have to line up before the subscription is accepted:

• Corporate authority. The company’s articles and by-laws permit the investment, and a resolution of the directors authorises it and names who may sign.
• Exemption eligibility. MIC shares are usually sold under the accredited investor exemption or the offering memorandum exemption in National Instrument 45-106. A corporation is assessed under the tests for entities, which differ from the individual thresholds; see who counts as an accredited investor. Confirm current definitions with a registered dealer.
• Know-your-client on the company. The exempt market dealer reviews the corporation, the people who own or control it, and its signing officers, and assesses suitability before any subscription.

The rest of the process — application, review, funding and ongoing account management — is the same as for an individual and is set out in how to invest, step by step.

How MIC income is taxed inside a corporation

MIC dividends are deemed to be interest, so in a corporation’s hands they are generally investment income, not an inter-corporate dividend. Subsection 130.1(2) of the Income Tax Act deems a taxable dividend from a MIC, other than a capital gains dividend, to be interest on a bond issued by the MIC; that deeming applies whether the shareholder is a person or a company.

For a Canadian-controlled private corporation (CCPC), three mechanisms follow:

1. A higher corporate rate on investment income. Investment income is taxed at a higher corporate rate than active business income that qualifies for the small business deduction.
2. A refundable portion. Part of the tax on investment income is refundable to the corporation when it pays taxable dividends to its shareholders, who then pay personal tax on those dividends. The system is designed so that income earned through a corporation and paid out bears broadly similar total tax to income earned personally, though results vary by province and year.
3. The passive-income effect. Passive investment income above a threshold reduces the corporation’s access to the small business deduction, which raises the tax on its active business income.

The rates, the refund mechanics and the passive-income threshold are set in the Income Tax Act and provincial legislation and change over time, so this page does not quote them. Other types of corporation are taxed differently. The general treatment of MIC income for every type of investor is in how mortgage investment income is taxed in Canada.

Worked example (illustrative)

Every figure is assumed for illustration; actual rates and refund amounts depend on the province, the year and the company’s facts.

A holding company invests $500,000 in MIC shares.

1. Portfolio earnings. Assume the MIC’s mortgages earn a gross yield of 10% on that capital: $500,000 × 10% = $50,000.
2. MIC-level costs. Assume management fees, administration and loss provisions of 2%: $500,000 × 2% = $10,000.
3. Distribution to the holding company. $50,000 − $10,000 = $40,000, an 8% net yield, received as deemed interest. Distributions are targets, not promises.
4. Corporate tax. Assume an illustrative 50% rate on investment income: $40,000 × 50% = $20,000, leaving $20,000 in the company.
5. Refund on paying dividends. Assume, illustratively, that $12,000 of that tax is refunded once the company pays enough taxable dividends to its owner. Net corporate tax becomes $20,000 − $12,000 = $8,000, and up to $40,000 − $8,000 = $32,000 can reach the owner as dividends, on which the owner pays personal tax at their own rate.
6. Passive-income effect. The $40,000 counts toward the passive-income threshold. If the company’s total passive income exceeds it, the cost appears as higher tax on the business’s active income, outside the investment itself.

Whether this route leaves more after all taxes than investing personally depends on the province, the year’s rates, the owner’s bracket when dividends are paid, and step 6. A higher yield in a mortgage investment reflects higher risk — higher return, higher risk — and the tax system does not change that.

Holding company mortgage investment: documents and paperwork

A holding company mortgage investment needs a corporate paper trail in addition to the investor documents an individual provides. A dealer or issuer will typically ask for:

• Articles of incorporation and any amendments — from the corporate minute book.
• A directors’ resolution authorising the investment and naming the signing officers — prepared by the company or its lawyer.
• The register of directors and officers, and information on who owns or controls the company — from the minute book and securities register.
• Evidence for the exemption relied on, such as financial statements — from the company’s accountant.
• Banking details for the company’s account, to which distributions are paid.
• The company’s business number, for tax reporting.

Before signing, the company receives and reviews the offering memorandum, with its audited financial statements and risk factors, and any risk acknowledgement form the exemption requires. The dealer’s registration can be checked on the CSA National Registration Search.

The 25% limit and the 10% registered-plan trap for family groups

Two separate percentage tests treat a family and its companies as one. The first is the MIC’s own condition: paragraph 130.1(6)(d) of the Income Tax Act prevents any shareholder, together with related persons, from holding more than 25% of the issued shares of any class. A holding company and the person who controls it are related, so their holdings are combined, and a MIC may cap or decline subscriptions to protect its status. This is one of the nine conditions a MIC must meet.

The second test applies to the owner’s registered plans. Under the prohibited-investment rules in section 207.01 of the Income Tax Act, MIC shares in the owner’s RRSP or TFSA can become a prohibited investment if the owner, with non-arm’s-length persons — which generally includes a company the owner controls — holds 10% or more of any class. A large holding-company position can therefore cause a problem in the owner’s personal plans. See when a MIC becomes a prohibited investment.

Benefits and risks of corporate investment in mortgages

The trade-offs, side by side:

Liquidity and redemption explains notice periods and the board’s right to defer or suspend redemptions — the point that matters most when the company might need its cash back.

Common mistakes corporate investors make

These come from the questions business owners and their accountants raise most often.

• Treating MIC dividends as inter-corporate dividends. They are deemed interest.
• Ignoring the small business deduction. The cost of passive income can appear in the operating company’s tax, not in the investment’s numbers.
• Investing working capital. Cash the business may need within the redemption notice period, or during a deferral, is a poor match for an illiquid holding.
• Paperwork that does not match. A resolution that names different signing officers from those who sign the subscription can delay it or require it to be re-signed.
• Forgetting the family group. The company’s shares count with the owner’s for the MIC’s 25% test and the registered-plan 10% test.
• Using individual thresholds for a company. Entity tests differ; confirm with the dealer.

The glossary defines terms such as CCPC, refundable tax and small business deduction.

What this means for a corporate mortgage investor

A corporation can generally invest in mortgages, usually by subscribing for MIC shares, if it qualifies under a prospectus exemption and its paperwork is in order. The income is deemed interest, taxed in a CCPC as investment income with a refundable portion, and it can affect the small business deduction, so the after-tax comparison with investing personally needs a tax professional’s model. The corporate wrapper does not change the investment, which still varies along seven axes — borrower, property, loan-to-value, security position, term, jurisdiction and investment structure.
