ETFs: What They Are and How They Work

What it is

An ETF (exchange-traded fund) is a basket of investments — often hundreds or thousands of stocks, bonds, or both — that you buy and sell on a stock exchange just like a single stock. One purchase gives you instant diversification instead of betting everything on one company.

How it works

1. The fund holds a collection of securities. For example, a Canadian stock ETF might hold shares in hundreds of Canadian companies at once.
2. You buy ETF units on an exchange (like the TSX) through any brokerage account, at whatever the market price is that moment — the same way you’d buy a stock.
3. The price tracks the basket’s value. Special market participants keep the ETF’s trading price very close to the actual value of what it holds (called the net asset value, or NAV).
4. Most ETFs are passive. Instead of a manager picking winners, the ETF simply follows a set of rules — like “hold the 200 largest Canadian companies.” This keeps costs low.
5. You earn returns the same ways as stocks: price growth plus distributions (the ETF passes along dividends and interest it collects to you).

What it’s used for

ETFs are the core building block of most long-term investment portfolios — retirement savings, a future down payment years away, or any goal with a long runway. They’re for investors who want broad market exposure without researching individual companies.

ETFs are NOT for money you need soon, and niche ETFs (leveraged, inverse, single-theme) are not beginner products — stick to broad, plain-vanilla ETFs while learning.

Who provides it in Canada

The big three ETF providers in Canada are Vanguard Canada, BlackRock (iShares), and BMO ETFs. You buy their ETFs through any Canadian brokerage — Wealthsimple, Questrade, National Bank Direct Brokerage, Interactive Brokers, or the bank-owned brokerages.

What it costs

• MER (management expense ratio): the annual fee, taken quietly from returns. Broad Canadian and US index ETFs often charge around 0.05%–0.25% per year; all-in-one diversified portfolios around 0.20%–0.25%. Always check the fund facts document for the current MER.
• In dollars: a 0.20% MER on a $10,000 investment costs about $20 per year. Compare that to a typical Canadian mutual fund at ~2% ($200/year on the same $10,000).
• Trading commissions: many brokerages charge $0 to buy ETFs; check current schedules.
• Currency conversion: buying US-listed ETFs involves USD conversion fees — check current rates. Canadian-listed ETFs that hold US stocks avoid this hassle.

Newcomer notes

• Same account requirements as stocks: age of majority, Canadian address, SIN for tax reporting. No citizenship required.
• ETFs can be held inside a TFSA, RRSP, or FHSA — where their growth is sheltered from tax. This is where most Canadians should hold them.
• Prefer Canadian-listed ETFs while starting out: no USD conversion, simpler taxes, and no cross-border complications.
• “All-in-one” asset allocation ETFs (a single fund holding a complete diversified portfolio) are arguably the simplest credible way for a beginner to invest.

Risks / watch-outs

• Diversified does not mean safe. A broad stock ETF still falls when markets fall — drops of 20–30% happen.
• Tracking error: an ETF can lag the index it follows slightly, because of fees and trading mechanics.
• Not all ETFs are simple. Leveraged, inverse, and narrow thematic ETFs can behave in surprising ways and decay over time. If you can’t explain what an ETF does in one sentence, don’t buy it yet.
• Distributions can be taxable in non-registered accounts — another reason to favour registered accounts.

FAQ

What’s the difference between an ETF and a mutual fund? ETFs trade on an exchange all day like stocks, usually have much lower fees, and have no minimum investment beyond the share price. Mutual funds are priced once daily, often carry higher fees, and are usually bought through an advisor.

What’s the difference between an ETF and an individual stock? One stock = one company (concentrated risk). One broad ETF = hundreds of companies (diversified). Beginners overwhelmingly do better starting diversified.

Do ETFs pay dividends? Yes — ETFs pass along the dividends and interest collected from their holdings as distributions, usually monthly, quarterly, or annually.

Should I buy Canadian-listed or US-listed ETFs? For most Canadians starting out: Canadian-listed. You avoid USD conversion fees and keep taxes simpler, and Canadian-listed ETFs already give you full access to US and global markets.

What does MER actually cost me in dollars? Multiply the MER by your investment. A 0.20% MER on $10,000 is about $20 per year; on $100,000 it’s about $200 per year. Small percentages compound into big differences over decades — which is exactly why low fees matter.
