Learn how to strategically realign your portfolio to maintain target allocations, minimize risk, and stay aligned with Canadian regulations and tax considerations.
Rebalancing is the essential final step in the portfolio management process, ensuring that a portfolio remains aligned with an investor’s objectives, risk tolerance, and time horizon. Over time, market fluctuations can cause asset classes to drift away from their target weights. Without periodic rebalancing, a portfolio may deviate from its intended risk/return profile, potentially compromising the investor’s long-term financial goals.
This section provides an in-depth look at why, when, and how to rebalance a Canadian investment portfolio, exploring practical strategies, tax implications, and real-world case studies from major Canadian financial institutions and robo-advisor platforms.
At its core, rebalancing is about risk management:
• Asset allocations drift when strong performers outweigh weaker ones, potentially increasing or decreasing a portfolio’s overall risk beyond an investor’s comfort level.
• Systematically realigning asset weights back to target allocations helps maintain consistency with the original investment policy statement (IPS).
• Without regular rebalancing, high-performing assets might dominate the portfolio, skewing both the risk and return potential.
Consider a balanced portfolio structured at 60% equities and 40% fixed income. If equities perform exceptionally well, the allocation might shift to 70% equities and 30% fixed income. While this may improve returns in the short term, it also exposes the investor to greater market risk if equities suddenly drop.
Rebalancing strategies vary depending on the investor’s goals, regulatory considerations, and taxation. The most frequently used triggers in the Canadian market are:
• A set interval (e.g., quarterly, semi-annually, or annually) is used to check allocations and rebalance if necessary.
• Advantage: Simple, predictable approach that ensures periodic evaluation.
• Disadvantage: May rebalance at inopportune times, incurring unnecessary costs.
• A “rebalancing threshold” is defined (e.g., ±5% deviation from the target allocation).
• Example: If a 60/40 portfolio’s equity component exceeds 65% or falls below 55%, a rebalance is triggered.
• Advantage: Targets significant deviations, limiting trade frequency.
• Disadvantage: Large market swings can trigger frequent trades, potentially increasing costs.
• A combination of time-based and threshold-based triggers.
• Example: Check the portfolio quarterly, but only rebalance if allocations deviate by 5% or more.
• Advantage: Offers a balanced approach, reducing the likelihood of missing significant market moves while avoiding excessive trading.
Rebalancing always comes with potential costs—both in trading fees and tax consequences. In Canada, these aspects include:
• Brokerage fees: Vary across Canadian brokerages such as RBC Direct Investing, TD Direct Investing, Questrade, etc.
• Bid-ask spreads: Especially relevant for thinly traded securities.
• Short-term redemption fees: Common for some mutual funds if sold before a specified holding period.
• Capital gains (or losses) may be realized in non-registered accounts once securities are sold.
• For registered accounts (RRSPs, TFSAs), capital gains are either tax-deferred (RRSP) or tax-free (TFSA).
• Refer to the Income Tax Act (Canada) for the rules on capital gains and losses, as well as the CRA website for the latest regulations.
• Strategies such as tax-loss harvesting and strategic use of dividend income can soften tax liabilities.
• Although there are no explicit regulatory mandates on how frequently to rebalance, the Canadian Investment Regulatory Organization (CIRO) and Canadian Securities Administrators (CSA) emphasize suitability and the “Know Your Client” (KYC) rule.
• Ensuring that a client’s portfolio remains consistent with their risk profile is a regulatory requirement. Rebalancing is one mechanism that helps maintain this consistency.
Below is an overview of the practical approaches Canadian investors and advisors might employ.
Robo-advisor platforms in Canada, such as Wealthsimple, Questrade Portfolios, and others, often provide automated rebalancing:
• Continuous monitoring of allocations, automatically triggering trades once allocations deviate from set thresholds.
• Incorporate tax-loss harvesting strategies.
• Accessible for investors with smaller portfolios or limited time.
Advanced asset management firms, including large Canadian pension funds, may use dynamic models to anticipate market changes:
• Shorter intervals for volatile markets; longer intervals for stable conditions.
• Quantitative algorithms to forecast potential risk/return trade-offs and optimize rebalancing decisions.
To illustrate the importance of rebalancing in a Canadian setting, consider a simplified scenario:
An investor opens a non-registered RBC Direct Investing account with a $100,000 balanced portfolio:
• 60% equities (Canadian, U.S., international)
• 40% fixed income (GICs, Government of Canada bonds)
After 12 months of strong equity performance, the breakdown is now:
• 68% equities
• 32% fixed income
The investor’s Investment Policy Statement states a rebalancing threshold of ±5%. By surpassing 65% in equities, the portfolio triggers a rebalance.
Upon selling the excess equities and buying fixed-income assets:
• Short-term gains are realized on certain equities, triggering capital gains tax.
• The investor uses some capital losses from previous years, carried forward under the Income Tax Act (Canada), to offset a portion of these gains.
After rebalancing, the new portfolio returns to the 60/40 target, aligning with the designated risk tolerance.
• Time-based rebalancing can fit neatly with an end-of-year tax planning session, optimizing capital loss harvests.
• Threshold-based rebalancing in Canada can be beneficial when large market swings occur, as it can capture abrupt shifts and rebalance at potentially advantageous points.
• Rebalancing is often done at the total portfolio level across all accounts (TFSA, RRSP, non-registered) to optimize tax efficiency.
• For example, you might sell an asset in an RRSP (no capital gains taxes triggered) rather than in a non-registered account (where it would generate a taxable event).
• In non-registered accounts, consider offsetting gains with realized losses or focusing on partial rebalancing (i.e., redirecting new contributions to underweight assets) to minimize taxable transactions.
• Consult resources such as “Tax-Efficient Investing in Canada” (various articles, books, and CRA bulletins) for more robust strategies.
Below is a simple flowchart illustrating the rebalancing decision:

Investors often face the following challenges when rebalancing:
Rebalancing is more than a mechanical exercise; it is a fundamental component of disciplined portfolio management. In the Canadian context, careful consideration of tax regulations, account structures (registered vs. non-registered), and market conditions ensures that rebalancing strategies remain cost-effective and aligned with an investor’s objectives. By systematically applying either time-based, threshold-based, or hybrid tactics, investors can preserve the integrity of their portfolio’s risk/return profile.
By following this seven-step portfolio management process—culminating in the final step of diligent rebalancing—advisors and investors can maintain continuous alignment with both client expectations and Canadian regulatory standards. The result is a portfolio that marries risk management with the opportunity for long-term investment success.
