Index Fund vs ETF in Canada: Which One Should You Buy?
An index fund and an ETF both track the market cheaply, but for most Canadians, one all-in-one ETF like XEQT is the simpler path.
The direct answer
You do not have to pick between indexing and ETFs. An ETF can be an index fund. The real question is how you want to buy it.
An index fund is any fund that tracks a market index instead of trying to beat it. An ETF is a way to package and trade a fund on a stock exchange. Most ETFs are index funds. Index mutual funds, like TD e-Series, hold the same kind of investments but you buy them directly from the fund company or your bank. For most Canadians, a single all-in-one ETF like XEQT is the simpler choice.
People treat these as rival strategies. They are not. Both give you a basket of hundreds or thousands of companies for a tiny fee. Both beat most professional stock pickers over long periods. The difference is the wrapper, not the idea.

Side-by-side comparison
Here is how index mutual funds and ETFs stack up on the things that actually affect your wallet and your habits.
| Feature | Index mutual fund (e.g. TD e-Series) | ETF (e.g. XEQT) |
|---|---|---|
| MER | Often 0.33% to 0.51% for equity funds | 0.20% for XEQT |
| Minimum to start | Often $100 initial, then small top-ups | The price of one share, or less with fractional shares |
| How you trade | Order once a day, priced at end of day | Trade anytime markets are open, like a stock |
| Trading costs | None at the fund company, but some platforms charge | Commission-free on some platforms, up to $9.99 on others |
| Auto-investing | Easy, works with exact dollar amounts | Works on some platforms, with fractional shares needed for exact dollars |
| Rebalancing | You do it yourself across several funds | Built into all-in-one ETFs |
| Tax treatment | Same rules in TFSA, RRSP and taxable accounts | Same rules in TFSA, RRSP and taxable accounts |
| Where you hold it | Bank or fund company accounts | Any brokerage account |
Notice the pattern. Index funds win on convenience for tiny, regular deposits. ETFs win on cost and simplicity of the portfolio. Taxes come out even, which surprises people.
Real example: TD e-Series vs XEQT
TD e-Series is the best-known index mutual fund option in Canada. Here is what building a global stock portfolio looks like with each.
To build global stock exposure with TD e-Series, you typically hold several funds: a Canadian index fund, a U.S. index fund, and an international index fund. Some investors add an emerging markets fund too. Each has its own MER, and you decide the mix.
With XEQT, you buy one ticker. It holds Canadian, U.S., international and emerging market stocks in a fixed mix, and BlackRock rebalances it for you. The MER is 0.20%.
| Step | TD e-Series approach | XEQT approach |
|---|---|---|
| Funds to buy | 3 to 4 | 1 |
| Blended cost | Depends on your mix, often higher than 0.20% | 0.20% MER |
| Rebalancing | You track and fix drift yourself | Automatic |
| Decisions to make | Mix percentages, when to rebalance | None |
| Where it lives | TD account (or a platform that offers the funds) | Any brokerage |
On a $50,000 portfolio, a gap of 0.15 percentage points costs about $75 a year. Not dramatic at first. But invest for 25 years and keep adding money, and the gap grows into thousands of dollars.
The bigger cost is behavioural. Multi-fund portfolios invite tinkering. You wonder whether to add more U.S., trim Canada, or chase last year’s winner. One fund removes the temptation.
Where index funds still win
I am pro-ETF, but fairness matters. Index mutual funds have real advantages in a few situations.
First, tiny automatic deposits. If you want to invest exactly $50 every payday, index mutual funds handle this cleanly because they sell in dollar amounts, not whole shares. Many ETF platforms now offer fractional shares, which closes the gap, but not every one does.
Second, no bid-ask spread. ETFs trade on an exchange, so there is a tiny gap between buy and sell prices. For a large, popular ETF like XEQT, that gap is usually very small, but it exists. Index funds skip it.
Third, bank-only investors. If you refuse to open a brokerage account and keep everything at your bank, index funds may be your path. That is a fine choice. A slightly higher fee beats not investing at all.
Do not let the perfect wrapper stop you from starting. A low-cost index fund bought today beats an ETF you keep researching for another year.
Taxes and account types
Good news: the wrapper rarely changes your tax bill.
Inside a TFSA or RRSP, you pay no tax on growth or distributions as you go, whether you hold an ETF or an index mutual fund. In a taxable account, both generate taxable distributions and capital gains when you sell.
One nuance: in taxable accounts, ETFs can be slightly more tax efficient because of how they handle redemptions, so they tend to distribute fewer capital gains than mutual funds. For a Canadian passive investor, the effect is usually small.
In taxable accounts, track your adjusted cost base carefully. It matters with either wrapper, especially if you reinvest distributions.
My verdict
For most Canadians, an all-in-one ETF is the simpler path. Buy it, add money regularly, and ignore the noise.
Here is the simple rule. If you want the lowest cost and the least work, buy an all-in-one ETF like XEQT. You get global diversification, automatic rebalancing and a low MER in a single purchase.
Choose index mutual funds only if you need exact-dollar automatic deposits and your platform does not support fractional ETF shares, or if you will only invest through your bank.
