How to Rebalance an ETF Portfolio in Canada: Step-by-Step Guide

A Canadian guide to rebalancing an ETF portfolio: set targets, measure drift, use 5% or 5/25 triggers, buy with new cash first, and avoid tax traps.

An 80/20 portfolio can become 86/14 after a strong run in stocks. The fix is simple in theory, but the practical questions are less so: how far off target is too far, should you sell, and which account should you use?

This guide covers the process from setting targets to placing trades, with a focus on using new contributions first and avoiding unnecessary tax in a non-registered account.

Want the exact trades for your portfolio? The FolioNorth rebalancing calculator takes your holdings, targets, and any new cash, and produces a buy-and-sell (or buy-only) trade list in whole shares.

TL;DR

Rebalancing is risk control, not a return booster. Vanguard's research finds that frequency and threshold choices make little difference to long-run risk-adjusted results. The job is keeping your portfolio near its intended risk level.
Pick one trigger rule and follow it: annual on a fixed date, a 5 percentage point band, or Larry Swedroe's 5/25 rule. Consistency matters more than the exact choice.
Use new money first. Directing contributions to whatever is underweight rebalances without selling and without a tax bill. For accumulators, that may be all you need.
Commissions are mostly gone. Wealthsimple, Questrade (since early 2025), and Qtrade (since October 2025) charge $0 commissions, but Questrade can still apply ECN or market fees to some order types and routing. Check the broker's current schedule before assuming a trade costs only the spread.
Tax matters in the taxable account. Selling winners realizes capital gains (one-half inclusion rate as of 2026), and the superficial loss rule can deny a loss repurchased within 30 days. When practical, do the selling inside the RRSP or TFSA.
Or opt out entirely: an all-in-one ETF like XEQT or VGRO rebalances itself for roughly 0.20% to 0.24% per year.

Who this is for

This is for Canadian DIY investors holding two or more funds across one or more accounts: the classic multi-ETF portfolio. If you hold a single asset-allocation ETF everywhere, skip to the all-in-one section. Rebalancing is not market timing; it is a way to return to the plan you already chose.

Why rebalance at all

A portfolio's asset mix is its risk setting. An 80/20 that drifts to 90/10 after a long bull market is riskier than the portfolio you chose, and will fall harder in the next drawdown. Rebalancing brings it back toward the original risk level.

It is not a reliable return booster. Vanguard's research finds little difference in risk-adjusted results across monthly, quarterly, and annual schedules or across reasonable threshold bands. Roughly annual rebalancing is a sensible default. Stocks usually outperform bonds, so a strict rebalancer may sell some future return; in exchange, the portfolio stays closer to its intended risk.

There is also a behavioural benefit. A written rule tells you to sell what has run up and buy what has fallen when your instincts may say otherwise. That is easier to follow than making the decision in the middle of a market scare.

The step-by-step

Step 1: Set your target weights

Start by writing down your asset mix at two levels: the stock/bond split, which is the main risk decision, and the equity split between Canadian, US, international, and emerging markets. If you need a starting template, the ETF split tool shows how major all-in-one funds divide their equity sleeves, while the Just Buy page covers the one-fund options. Targets must add up to 100% and should not change every time a market moves.

Step 2: Measure your drift

Drift is the current weight minus the target weight, measured across the household portfolio rather than one account at a time. If US equity is 43.8% of the total against a 40% target, the drift is +3.8 percentage points. Check it once or twice a year, or whenever you invest new money. A spreadsheet works; the rebalancing calculator does the arithmetic and ranks the holdings by drift.

Step 3: Pick a trigger rule and stick to it

The trigger tells you when drift becomes a trade. The exact threshold matters less than choosing a reasonable rule and applying it consistently.

Rule	How it works	Typical trading	Best for
Calendar	Rebalance on a fixed date, annually or semi-annually, regardless of drift	Once or twice a year	People who want zero monitoring
Threshold (5% band)	Rebalance any holding that drifts 5 percentage points from target	Rarely; mostly after big market moves	People who check occasionally and want to act only when it matters
5/25 rule (Swedroe)	Rebalance when a holding drifts 5 percentage points absolutely OR 25% relative to its target, whichever trips first	Like the 5% band, but catches small allocations	Portfolios with small sleeves (5% to 15% positions)
Contribution-only	Never sell; direct every contribution to whatever is most underweight	Every contribution	Accumulators adding regularly

The 5/25 refinement matters for small positions. A 40% US-equity target trips the 5% band at 45% or 35%, but a 10% emerging-markets sleeve would have to nearly halve before moving 5 points. Under the relative test, 25% of a 10% target is 2.5 points, so the sleeve trips at 12.5% or 7.5%. Our preference is to check annually and trade only when a band is breached.

Step 4: Use new money first

If you are still contributing, this is usually the cheapest way to rebalance. Direct the contribution to the most underweight holding instead of splitting it to match the targets. Dividends can work the same way: send the cash to the laggard rather than reinvesting in the overweight fund. Nothing is sold, so no gain is realized. With regular contributions, you may go years without needing a sale.

Step 5: Place the trades

When new money is not enough, calculate the trades. The rebalancing calculator uses this same approach. Suppose you hold a $100,000 four-fund portfolio and have $5,000 of new cash, making the rebalanced total $105,000:

Holding	Target	Current value	Target value (on $105,000)	Gap
VUN (US equity)	40%	$46,000	$42,000	$4,000 overweight
XIC (Canadian equity)	30%	$27,000	$31,500	$4,500 underweight
XEF (international)	20%	$18,000	$21,000	$3,000 underweight
ZAG (bonds)	10%	$9,000	$10,500	$1,500 underweight

In buy-and-sell mode, sell about $4,000 of VUN. The proceeds plus the $5,000 of cash fund the three buys exactly: $4,500 of XIC, $3,000 of XEF, and $1,500 of ZAG.

In buy-only mode, sell nothing. The underweights need $9,000 total but you have $5,000, so each buy is scaled to five ninths of its full size: roughly $2,500 of XIC, $1,667 of XEF, and $833 of ZAG. VUN remains overweight, but future contributions can close the gap. In a non-registered account, buy-only avoids realizing a gain.

Either way, real trades happen in whole shares, so round each amount down to whole shares and expect a few dollars of leftover cash. That is normal.

On cost: Wealthsimple, Questrade, and Qtrade all advertise $0 commissions (see our brokerage comparison). Questrade notes that ECN or market fees can still apply to some order types and routing, particularly in certain US and overnight trades. For ordinary liquid ETF orders, the main remaining friction is usually the bid-ask spread; currency conversion on US-listed holdings can matter much more than the trade itself.

Step 6: Write it down

Record the targets, the trigger, and the next review date. One paragraph is enough. The calculator's saved link handles the numbers; the written rule keeps the process consistent when markets are falling.

The tax side: gains, losses, and the 30-day trap

Buying and selling inside an RRSP, TFSA, FHSA, or RESP does not trigger immediate capital-gain or capital-loss reporting. Registered accounts are therefore useful places to do most of the selling.

In a taxable account, selling an overweight winner realizes a capital gain. As of 2026, one half of the gain is added to taxable income. (The proposed two-thirds rate was cancelled in March 2025 and never became law; confirm current CRA rules before a large sale.) If you rebalance by selling winners, the tax bill is part of the calculation.

Selling a loser has a separate trap: the superficial loss rule. If you or an affiliated person buys the same or identical property within the period beginning 30 days before the sale and ending 30 days after, and still holds it at the end of that period, the loss is denied. That includes a spouse or common-law partner and trusts such as your RRSP or TFSA. A denied loss is added to the adjusted cost base of a taxable repurchase, but is lost when the repurchase happens inside an RRSP or TFSA. If you are tax-loss harvesting while rebalancing, use a similar but not identical fund and respect the 30-day window on both sides.

Rebalance the household, not the account

Treat all of your accounts as one portfolio with one set of targets. Each account does not need to hold 40% US equity; the household total is what matters. When a rebalance requires selling, that lets you sell inside the RRSP or TFSA and leave the taxable account alone.

The same household view helps with asset location: US-listed funds in an RRSP avoid the 15% dividend withholding tax that a TFSA cannot recover. The asset location guide and optimizer cover that decision in detail.

The never-rebalance alternative: all-in-one ETFs

If you know you will not follow a rebalancing rule during a large drawdown, consider an asset-allocation ETF. XEQT and VEQT are 100% equity; XGRO and VGRO are 80/20. They hold diversified portfolios and rebalance internally for an MER of roughly 0.20% to 0.24%, often a little more than building the same portfolio yourself. The Just Buy page compares the options.

Bottom line

Our default is simple: write down the targets, check them once a year, and trade only when a holding is 5 percentage points (or 25% relatively) off target. Use new contributions for smaller gaps. When selling is necessary, sell inside registered accounts first and check the superficial-loss rules in taxable. If you do not want to manage any of this, an all-in-one ETF is a reasonable solution. Run the numbers through the rebalancing calculator before trading.

A note on scope: FolioNorth's tools are educational and this is not personalized investment or tax advice. Inclusion rates, account rules, and broker pricing change, so confirm current CRA rules before acting, and bring a professional into any large taxable rebalance. See our disclosure.

Frequently asked questions

How often should I rebalance my portfolio?+

Once a year is a reasonable default, with an extra check when a holding moves roughly 5 percentage points from its target. Vanguard's research finds no meaningful difference in risk-adjusted outcomes between monthly, quarterly, and annual rebalancing. More frequent checks add work and, in taxable accounts, can add trades and tax.

Does rebalancing trigger taxes in Canada?+

Not for an ordinary rebalance inside a registered account: a sale in an RRSP, TFSA, FHSA, or RESP does not trigger immediate capital-gain or capital-loss reporting. In a non-registered account, selling an overweight holding realizes a capital gain, and as of 2026 one half of the gain is taxable at your marginal rate (the proposed two-thirds inclusion rate was cancelled in March 2025). You can often reduce realized gains by directing new contributions to underweight holdings and doing necessary sales inside registered accounts.

What is the 5/25 rule for rebalancing?+

A trigger rule popularized by Larry Swedroe: rebalance a holding when it drifts either 5 percentage points from its target in absolute terms or 25% of the target in relative terms, whichever comes first. The relative leg exists for small positions; a 10% sleeve trips at 7.5% or 12.5% (25% of 10% is 2.5 points), long before it could move a full 5 points. For large allocations the absolute band governs.

Can I rebalance my portfolio without selling anything?+

Usually. Direct new contributions, dividends, and distributions to the most underweight holding. Over time, that reduces drift without selling or triggering tax. The FolioNorth rebalancing calculator has a buy-only mode that suppresses sells and scales the buys to fit your new cash.

Should I just buy an all-in-one ETF instead of rebalancing myself?+

If you are unlikely to follow a rebalancing rule through a real crash, an all-in-one fund is a good alternative. XEQT, VEQT, XGRO, and VGRO rebalance internally for an MER of roughly 0.20% to 0.24%, often about 0.10% more than a DIY multi-ETF portfolio. That premium buys automatic maintenance. DIY gives you more control over asset location; the one-fund option removes the work.
