What Is Portfolio Rebalancing and When Should You Do It in Canada?

You open your investment account one afternoon and notice your numbers look a bit different than when you started. The stocks you own have climbed while your bonds barely moved, and suddenly your portfolio is a lot heavier on one side than you planned. That shift happens to everyone — markets move, and over time they pull your mix of investments away from what you originally intended. Portfolio rebalancing is how you fix that. It sounds technical, but the concept is simple and it’s one of the most practical habits you can build as an investor in your 20s or 30s.

Quick answer: Portfolio rebalancing means selling some of your investments that have grown too large and buying more of the ones that have fallen behind, so your portfolio returns to your target mix. Most Canadian investors in their 20s should rebalance once or twice a year, or whenever their allocation drifts more than 5–10% from their target.

What does portfolio rebalancing actually mean?

Rebalancing means bringing your portfolio back to its original target allocation after market movements have pushed it off course. Say you started with 80% stocks and 20% bonds. After a strong year for equities, stocks might now make up 90% of your portfolio. Rebalancing means selling some of those stocks and putting the proceeds into bonds until you’re back at 80/20.

The goal is risk management, not chasing returns. A portfolio that was designed for moderate risk can quietly become an aggressive one just by sitting still during a bull market. Younger investors often hear “you don’t need bonds yet,” and that’s sometimes true — but even an all-equity portfolio can drift between Canadian stocks, US stocks, and international holdings in ways that affect your actual risk level. Rebalancing keeps your portfolio doing what you designed it to do, rather than what the market happened to do to it.

How often should you rebalance your portfolio in Canada?

Most financial guidance settles on rebalancing once or twice a year, or when your allocation drifts beyond a set threshold — commonly 5% to 10% from your target. Both approaches work; the right one depends on how hands-on you want to be.

The calendar approach is the simplest: pick a date (many people use their birthday, or January and July) and rebalance regardless of how much drift has occurred. The threshold approach means checking periodically and only rebalancing when something is noticeably off. A common rule is to rebalance if any asset class is more than 5% away from its target weight.

For most Canadian investors using low-cost ETFs inside a TFSA or RRSP, rebalancing once a year is enough. If you’re using a robo-advisor like Wealthsimple Invest, it rebalances automatically — so you don’t have to think about it at all. If you’re a self-directed investor on Questrade or Wealthsimple Trade, set a recurring calendar reminder and review your holdings once a year.

Quick tip: If you make regular contributions to your portfolio, direct new money into the underweight asset class first. This is called “rebalancing with contributions” and can reduce how often you need to sell anything — which saves on taxes in a non-registered account.

Does rebalancing cost you money in Canada?

Inside a registered account like a TFSA or RRSP, rebalancing is essentially free from a tax perspective. You can sell and buy without triggering any capital gains, which makes these accounts the ideal place to do your rebalancing activity. This is one reason many Canadians keep their most volatile holdings inside their TFSA.

In a non-registered (taxable) account, selling an investment that has grown means realizing a capital gain, and the CRA will want a portion of it. The capital gains inclusion rate for 2026 is a relevant factor here — here’s a breakdown of how it affects you. In a taxable account, you can soften the tax hit by directing new contributions to underweight assets rather than selling overweight ones.

Transaction fees are mostly a non-issue today. Most Canadian brokerages offer commission-free ETF trades, and if you hold funds like XEQT or VGRO that rebalance internally, you may rarely need to rebalance manually at all.

Should you even bother rebalancing in your 20s?

Yes — but it matters more as your portfolio grows. When you have $5,000 invested, a 10% drift in allocation isn’t a big deal in dollar terms. When you have $50,000, that same drift represents $5,000 of unplanned risk exposure. Starting the habit early means it’ll feel automatic by the time it actually matters.

The other reason to start now is psychological. Rebalancing forces you to sell what’s been doing well and buy what’s been doing poorly — essentially buying low and selling high in a disciplined way. That’s the opposite of what most investors naturally do, which is chase recent performance. The discipline of rebalancing can meaningfully improve long-term returns, not because of market timing, but because it prevents you from accidentally loading up on the thing that just went up right before it comes down.

Frequently Asked Questions

What is portfolio rebalancing in simple terms?

Portfolio rebalancing means adjusting your investments so they return to the percentages you originally intended. If you planned to have 80% in stocks and 20% in bonds but your stocks grew to 90%, rebalancing means selling some stocks and buying more bonds to get back to 80/20.

How often should I rebalance my portfolio as a Canadian investor?

Once or twice a year is enough for most people. You can also use a threshold rule: rebalance whenever an asset class drifts more than 5–10% from its target. If you use a robo-advisor, rebalancing happens automatically without you doing anything.

Is there a tax cost to rebalancing in Canada?

Inside a TFSA or RRSP, there is no tax when you sell to rebalance — gains in these accounts are sheltered. In a non-registered account, selling investments that have appreciated triggers a capital gain, which is taxable in the year you sell. For this reason, most Canadians prefer to rebalance inside their registered accounts first.

Can I rebalance without selling anything?

Yes. If you’re regularly adding money to your portfolio, you can direct new contributions toward whichever asset class is underweight. This brings your allocation back into balance without triggering any sales or capital gains. It’s called rebalancing with contributions and works well when your portfolio is still growing.

Do ETF funds like XEQT or VGRO rebalance themselves?

Yes. All-in-one ETFs like iShares XEQT, XBAL, or Vanguard’s VGRO automatically maintain their internal allocation across hundreds of underlying holdings. If you hold one of these funds, you don’t need to rebalance manually — the fund manager handles it for you, which is one reason they’re so popular with beginner investors.
