Rebalancing Your Portfolio in Canada

Portfolio rebalancing is the process of bringing your investments back to your target asset allocation after market movements cause it to drift. If you started with a 70/30 stock-bond split and equities performed well, you might find yourself at 80/20 — taking on more risk than intended. Rebalancing corrects this drift and enforces the discipline of buying low and selling high.

Why Rebalancing Matters

Without rebalancing, a portfolio naturally becomes more aggressive over time as equities tend to outperform bonds. An investor who started with a moderate 60/40 allocation in 2010 without rebalancing would have arrived at approximately 80/20 by 2021 — much more equity exposure than originally intended. When the 2022 correction hit, they experienced larger losses than their risk tolerance was designed for.

When to Rebalance

There are two common approaches:

Calendar Rebalancing

Review and rebalance once per year, typically in January or on your investment anniversary. Simple, predictable, and avoids over-tinkering. Annual rebalancing is sufficient for most long-term investors.

Threshold Rebalancing

Rebalance whenever any asset class deviates more than 5–10% from its target. If your target is 70% equities and you've drifted to 77%, rebalance. More precise but requires monitoring. Often combined with calendar rebalancing — check once a year and only rebalance if drift exceeds 5%.

How to Rebalance Tax-Efficiently in Canada

Method 1: Contribute New Money

The most tax-efficient rebalancing method for investors who are still in the accumulation phase. Instead of selling overweighted assets, direct new contributions to underweighted asset classes. This brings the portfolio back toward target allocation without triggering any capital gains. Ideal for any account type.

Method 2: Sell and Reinvest (Registered Accounts First)

When rebalancing requires actual selling, do it in registered accounts (TFSA, RRSP) first. Selling within these accounts has no tax consequences. Only sell in taxable accounts if necessary, and be mindful of capital gains implications.

Method 3: DRIP Redirection

If you receive dividends or distributions, direct them toward underweighted asset classes rather than reinvesting in the same security. This passive rebalancing technique reduces drift without generating transactions.

Rebalancing with All-in-One ETFs

If you hold a single all-in-one ETF (like XGRO or VGRO), congratulations — you don't need to rebalance. The ETF does it automatically. This is one of the strongest arguments for using all-in-one funds, especially for investors who find rebalancing confusing or time-consuming. See our top all-in-one ETF picks.

Rebalancing Bands: Sample Schedule

A common approach used by passive investors:

• Check allocation once per year (January 1)
• Only rebalance if any asset class is more than 5% from target
• Rebalance using new contributions where possible
• Sell only in registered accounts if contributions aren't sufficient
• Never sell in a taxable account unless absolutely necessary

Psychological Benefits of Rebalancing

Beyond risk management, rebalancing has a valuable psychological function: it forces you to systematically buy what's cheap (underweighted assets that underperformed) and trim what's expensive (overweighted assets that outperformed). This mechanical discipline prevents the "buy high, sell low" behavior that destroys returns for most individual investors.
