Should I Hold Mutual Funds or ETFs?
Usually ETFs, because the difference that matters is cost rather than structure. Both pool money and both hold a portfolio, but Canadian mutual fund fees remain among the highest in the world and the gap compounds against you for as long as you hold.
- The answer:: Both pool investor money into a portfolio; ETFs trade on an exchange and generally carry materially lower management fees.
- The trap:: Comparing a fund's stated return against an index without noticing the fee is already deducted from one and not the other.
- The recommendation:: Check what advice you are receiving for the fee, because an embedded commission pays for service you may not be getting.
Where the AI summary above gets this wrong
"ETFs are always cheaper than mutual funds."
That's surface-true. Here's what it misses:
- Not always, but usually by a wide margin — Some index mutual funds are competitive; the typical actively managed Canadian fund is not.
- Part of the fee pays for advice — Embedded commissions historically compensated the adviser, so the fee bought service as well as management.
- Trading costs differ — ETFs are bought through an exchange with a spread and possibly a commission; mutual funds transact at end-of-day value with no spread.
01 What actually differs
Both are pooled vehicles holding a portfolio on behalf of many investors. A mutual fund transacts once daily at its net asset value; an ETF trades on an exchange throughout the day at a market price that can differ slightly from that value.
The structural differences are minor for a long-term holder. The cost difference is not: Canadian management fees on actively managed funds remain among the highest internationally, and the drag compounds every year — the arithmetic is in the true impact of MERs.

02 What the fee has historically bought
A substantial part of a Canadian mutual fund's fee has historically been an embedded commission paid to the adviser who sold it. That means the fee purchased advice as well as portfolio management, which is a legitimate service where it is actually delivered.
Regulatory changes have altered how those commissions work, but the underlying question is unchanged: what advice are you receiving, and would you pay for it separately at that price? Where the answer is none, the fee is buying only management.
Shows: what an amount becomes after your chosen number of years at a fixed return. Ignores: tax, fees, inflation, and any variation in returns from year to year.

03 Where a mutual fund still wins
For small, regular contributions, a mutual fund transacts at end-of-day value with no bid-ask spread and often no commission, which suits an automatic monthly plan better than an exchange purchase.
Some low-cost index mutual funds are genuinely competitive with ETFs and remove the trading friction entirely. The location decisions for either are in asset location across accounts.
Switching between them in a non-registered account is a disposition, so a decision to move from a high-fee fund to an ETF realises whatever gain has accrued. Inside a registered account there is no such cost, which is why the change is usually made there first and staged over years in the taxable account.
The fee conversation in Canada is still worth having because the numbers are still bad by international standards. A percentage point a year over thirty years is not a rounding difference; it is a meaningful share of the final balance, handed over for a service many holders never receive.
FAQ
Should I hold mutual funds or ETFs?
Usually ETFs, because the difference that matters over time is cost and Canadian mutual fund fees remain among the highest in the world.
Are ETFs always cheaper?
Usually by a wide margin, but not always. Some low-cost index mutual funds are competitive, particularly for small regular contributions where trading costs matter.
What does a mutual fund fee pay for?
Portfolio management and, historically, an embedded commission compensating the adviser who sold it. Whether that advice is being delivered is the question worth asking.
