Margin Trading Risks: Canadian Investors Face Calls as Debt Climbs

Canadian investors significantly increased their use of margin debt in the months leading up to the escalation of geopolitical tensions in the Middle East, raising concerns about potential vulnerabilities as markets navigate increased uncertainty. Data released this week by the Canadian Investment Regulatory Organization (CIRO) revealed that total client margin debt reached $47.3 billion in January, just $1 million shy of the all-time high recorded in November 2025, and a more than 23% increase year-over-year.

The Appeal – and Risk – of Leverage

Margin trading allows investors to borrow funds from brokerages to amplify potential returns, using their existing cash or securities as collateral. Although this strategy can boost profits in a rising market, it also magnifies losses when asset values decline. Investors can face a “margin call” – a demand to deposit additional funds or securities – if their collateral falls below a certain threshold, potentially leading to forced sales of holdings. The experience of Jeffrey Yao, a Vancouver-based IT professional, illustrates the risks. Following U.S. Trade tariff announcements last April, Yao received a margin call and had to quickly transfer funds to his Wealthsimple account to avoid liquidation, as reported by The Globe and Mail.

Debt Levels and Market Timing

The surge in margin debt occurred as Canadian stocks experienced a strong performance in 2023. However, the outbreak of conflict in the Middle East has triggered market volatility, with the S&P/TSX Composite Index erasing its year-to-date gains and nearing a correction – a 10% drop from recent peaks. This timing is particularly concerning, as investors who leveraged their positions may now be more exposed to losses. Oxford Economics’ recent survey indicates that one in six global companies now anticipate a worldwide recession this year, a significant increase since before the war began, according to a note from Jamie Thompson, Oxford’s head of macro scenarios.

Bank of Canada Signals Caution

Adding to the cautious outlook, the Bank of Canada, in its recent interest rate statement, highlighted concerns about weaker economic activity, elevated uncertainty, and rising inflation risks linked to higher energy prices. These factors collectively create a challenging environment for investors, especially those utilizing margin.

Brokerage Demand and Competitive Landscape

Despite the inherent risks, demand for margin accounts remains strong. Wealthsimple reported that margin accounts have been “one of the most requested products in [their] history,” with rapid adoption following their introduction in February 2025. Other major Canadian brokerages, including TD Direct Investing, Interactive Brokers, Scotia iTrade, Questrade, and CIBC Investor’s Edge, have long offered margin accounts. Newer players, like Moomoo Financial Canada, are attracting clients by offering lower margin borrowing rates, a strategy CEO Michael Arbus acknowledges is a key driver of recent registrations. Arbus stated in an interview that margin is frequently used on their platform by active traders pursuing option strategies.

Systemic Risk and Household Debt

While CIRO sets borrowing limits for margin accounts, and individual brokerages may impose stricter controls, experts generally believe that margin debt currently poses a negligible systemic risk to the Canadian financial system. However, the increasing indebtedness of Canadian households is a broader concern. Statistics Canada data shows that total household credit market debt surpassed $3.2 trillion in the fourth quarter of 2025, a 4.4% increase year-over-year. Which means Canadian households now carry $1.77 in credit market debt for every dollar of disposable income – a fifth consecutive quarterly rise in this ratio.

Amplified Vulnerability

Cyrus Kanga, a finance instructor at Camosun College’s School of Business and a former equities sales trader at CLSA, emphasizes the potential for amplified losses. “It is fine when things are going well, but the volatility is amplified and you can’t really predict when something’s going to happen,” he said. He also points out that investors forced to liquidate positions during a downturn miss out on any subsequent recovery.

The Asymmetry of Risk

The risks associated with margin trading are particularly acute in a volatile market. Even if markets rebound, investors who were forced to sell during a slump may not have the opportunity to participate in the recovery. This asymmetry of risk underscores the importance of careful consideration and risk management when utilizing leverage.

What to Consider Going Forward

The current environment demands a cautious approach from investors. The combination of high household debt levels, geopolitical uncertainty, and potential economic slowdowns creates a challenging backdrop. Investors should carefully assess their risk tolerance and consider the potential consequences of margin calls before leveraging their investments. Brokerages have a responsibility to ensure clients understand the risks involved, and regulators will likely continue to monitor margin debt levels closely. The potential for further market volatility suggests that a period of heightened caution is warranted.
