Investment line of credit in Canada: how it works and alternatives for investors

Many investors eventually encounter the concept of borrowing money to invest. In Canada, this can take several forms, including a traditional investment line of credit, an investment loan, a home equity line of credit, or margin borrowing through a brokerage account.

An investment line of credit generally refers to a borrowing arrangement that allows an investor to access funds for investing purposes. The borrowed funds may be used to purchase securities, contribute to an investment portfolio, or gain additional market exposure.

While the concept may appear straightforward, borrowing to invest introduces additional risks. Using borrowed money can magnify gains if investments increase in value, but it can also magnify losses if investments decline. Investors may also need to manage ongoing interest payments, repayment obligations, and changing market conditions.

Some brokerages offer margin-based buying power through a margin account. These arrangements differ from a traditional bank-issued line of credit because the available borrowing capacity may depend on eligible assets held within the account.

Questrade Margin Power is one example of margin buying power. It should not be viewed as a traditional bank line of credit. Instead, it is connected to a margin account and may provide additional buying power based on eligible assets.

What is an investment line of credit?

An investment line of credit generally refers to a borrowing arrangement used to access funds for investing purposes.

Like other forms of credit, a line of credit allows borrowers to access funds up to an approved credit limit. Interest may apply only to the amount borrowed rather than the entire available limit.

Some investment-related borrowing arrangements may be secured, while others may be unsecured. The structure often depends on the lender, the type of account, and the assets available as collateral.

In certain cases, investments, property, or other assets may be used to support borrowing capacity. An investment secured line of credit may rely on eligible assets as security for the loan.

Borrowing to invest differs from investing with existing savings. When borrowed funds are used, investors take on leverage. Leverage increases market exposure and may affect both gains and losses.

Investment line of credit: quick definition

An investment line of credit is a form of borrowing used to invest. It can increase the amount available to invest, but it also adds interest costs and can magnify losses if investments decline.

The exact structure of a line of credit for investments may vary by lender, account type, and borrowing arrangement.

How borrowing to invest works

The mechanics of borrowing to invest can often be explained through a simple sequence.

1. The investor accesses borrowed funds

The investor obtains access to a credit line, loan proceeds, or margin buying power.

2. The investor purchases investments

The borrowed funds are used to purchase investments such as stocks, exchange-traded funds (ETFs), mutual funds, or other securities.

3. Interest applies

The investor generally begins to pay interest on the borrowed amount. The applicable interest rate may be fixed or variable, depending on the borrowing arrangement.

4. Investment values change

The value of the investments may increase or decrease based on market performance and market conditions.

5. Gains or losses are magnified

Because the investor has more money invested than they otherwise would have had, gains and losses may both become larger.

6. Repayment obligations continue

Regardless of investment performance, the borrowed funds typically remain subject to repayment requirements and ongoing interest charges.

For illustrative purposes, consider an investor who uses borrowed funds to purchase additional securities. If the investments rise by 10%, the gain applies to a larger invested amount. If the investments decline by 10%, the loss also applies to the larger invested amount, while the borrowed funds still need to be repaid.

Is an investment line of credit the same as margin buying power?

Although these concepts are often discussed together, they generally refer to different types of borrowing.

A traditional line of credit is typically provided by a bank or lender. The borrower receives access to a revolving source of credit up to an approved limit.

A secured line of credit may use assets such as home equity, investments, or other collateral to support borrowing.

Margin buying power operates differently. Margin buying power is connected to a brokerage margin account and depends on the value and eligibility of assets held within that account. The amount available may fluctuate over time.

If asset values rise, available buying power may increase. If asset values decline, available buying power may decrease.

Margin borrowing may also be subject to:

• Margin requirements

• Maintenance requirements

• Margin calls

• Security eligibility rules

Types of borrowing investors may compare

Investors researching borrowing options may encounter several different products.

Traditional line of credit

A traditional line of credit is typically offered by a bank or lender. It may be secured or unsecured and allows borrowers to access funds up to a specified credit limit.

Investment secured line of credit

An investment secured line of credit in Canada that investors may encounter often uses eligible investments or other assets as collateral.

The amount available may depend on the value of the pledged assets and lender requirements.

Home equity line of credit

A home equity line of credit uses home equity as collateral.

This borrowing arrangement differs from margin borrowing because it is tied to real estate rather than brokerage account assets.

Investment loan

An investment loan generally provides a lump sum amount at the start of the borrowing arrangement.

Unlike a revolving line of credit, additional borrowing may require a new application or approval process.

Margin account buying power

Margin buying power is connected directly to a brokerage account.

Eligible securities may increase borrowing capacity, but available buying power can change based on account value and margin requirements.

Benefits of using borrowed money to invest

Some investors consider borrowing to invest because it can provide additional investing capacity.

Potential benefits may include:

Increased market exposure

Borrowing may allow investors to gain exposure to a larger amount of investments than they could purchase using cash alone. However, larger exposure also increases downside risk.

Access to investment opportunities

Borrowed funds may allow investors to participate in investment opportunities without immediately selling existing assets.

At the same time, interest costs and market risk continue to apply.

Portfolio flexibility

Experienced investors may view borrowing arrangements as one component of broader investment strategies. However, leverage can increase complexity and may require ongoing monitoring.

Potential tax considerations

In some situations, interest paid on borrowed funds used for investing may have tax implications.

Tax treatment depends on individual circumstances and applicable tax rules. Investors may wish to seek professional tax advice regarding their specific situation.

Any potential benefit should be evaluated alongside borrowing costs, risk tolerance, and overall financial circumstances.

Risks of an investment line of credit or margin borrowing

Borrowing to invest can introduce substantial risks.

Losses can be magnified

Leverage increases exposure to market movements. If investments decline, losses may be larger than they would have been without borrowing. The borrowed amount still needs to be repaid regardless of investment performance. Losses can exceed your initial cash deposit, resulting in a negative balance (deficit) that you are required to repay out-of-pocket. 

Interest costs can reduce returns

Interest costs continue to apply while money remains borrowed. Even if investments increase in value, borrowing costs may reduce overall gains. In some situations, interest expenses may exceed investment gains.

Margin requirements can change

Margin accounts operate under specific requirements. Changes in account value, security eligibility, or brokerage policies may affect available borrowing capacity.

Margin calls may require action

If account equity falls below required levels, a margin call may occur.

The investor may need to:

• Deposit additional funds

• Add eligible securities

• Reduce borrowing

• Sell investments

These actions may occur during unfavorable market conditions.

Investment values can decline quickly

Financial markets can experience periods of volatility. Rapid price declines may affect leveraged portfolios more significantly than non-leveraged portfolios.

Borrowing to invest may not be suitable for everyone

Investors with limited investing experience or low risk tolerance may find leverage difficult to manage.

Example: how leverage can affect gains and losses

The following scenario is hypothetical and intended for educational illustration only.

If investments rise

An investor contributes $10,000 and accesses $5,000 in borrowed funds.

The total amount invested becomes $15,000.

If the investment increases by 10%, the portfolio value increases by $1,500 before interest costs, fees, and taxes.

Without borrowing, a 10% increase on $10,000 would equal $1,000.

If investments fall

Using the same example, a 10% decline would reduce the $15,000 investment by $1,500.

Without borrowing, the decline would have been $1,000 on a $10,000 investment.

The investor would still owe the borrowed amount, and interest may continue to apply.

Why this matters

Leverage changes the risk profile of an investment portfolio. Potential gains may become larger, but potential losses may also become larger. Understanding both outcomes is an important part of evaluating leveraged investing.

How Margin Power works with a margin account

Margin Power is connected to a brokerage margin account rather than a traditional bank-issued line of credit. Eligible assets held within the account may contribute to additional buying power. As account values change, available buying power may also change.

Because Margin Power operates within a margin account structure, investors remain subject to margin requirements and other account rules.

With Margin Power, eligible assets may help increase the buying power available in a margin account. This means investors may be able to access additional capacity to invest without treating the product like a traditional bank-issued line of credit.

Because the buying power is tied to margin account rules and eligible assets, it can change as market conditions and account values change.

Investors considering margin investing may wish to understand how margin requirements, borrowing costs, and account eligibility affect available buying power.

Final thoughts: understand the risks before borrowing to invest

An investment line of credit, investment loan, or margin borrowing arrangement can increase the amount available for investing. At the same time, borrowing introduces additional costs, obligations, and risks.

Leverage may increase exposure to market gains, but it can also magnify losses. Interest costs, margin requirements, and changing market conditions can affect investment outcomes.

Margin Power should be understood as margin buying power connected to a margin account rather than a traditional bank-issued line of credit. The amount available may depend on eligible assets, account value, and margin requirements.

Before using borrowed money to invest, investors may benefit from understanding how the borrowing arrangement works, what costs apply, and what could happen during different market scenarios. Learning about leverage, margin requirements, and alternative approaches can help support informed investment decisions.
