Why Canadian Covered Call ETFs Are Built on Banks, Energy and Gold

Line up every covered call ETF sold in Canada and a pattern appears immediately. Banks. Oil and gas. Gold miners. Telecoms. Utilities. Then, abruptly, funds full of Microsoft, Eli Lilly and Palantir, priced in Canadian dollars and sold on the Toronto Stock Exchange.

That shape is not an accident of marketing. It is what happens when a product that requires liquid listed options meets an equity market concentrated in four industries. Understanding it tells you more about which Canadian fund to hold than any yield table will.

Start with the index, because everything follows from it

The S&P/TSX Capped Composite, as reported by BMO's ZCN at 31 August 2026, breaks down like this. The S&P 500 column comes from the SPDR SPY fact sheet at 30 June 2026.

Three sectors make up 69.9% of the Canadian index. The same three make up 16.6% of the American one. Five banks alone account for 22.0% of Canada: Royal Bank at 7.64%, TD at 5.40%, BMO at 3.20%, Scotiabank at 3.01% and CIBC at 2.79%. The top ten names are 37.7% of the whole market.

Health care is the number worth pausing on. At 0.29%, there is roughly thirty times more gold than health care in the Canadian market. Hold that thought.

The gold weighting is new, and most commentary has not caught up

Materials at 19% is not a permanent feature of Canada. In BMO's quarterly disclosure for the same fund at 30 September 2019, the sector was 10.8%. It has almost doubled, and the reason is precious metals rather than commodities broadly.

In the iShares S&P/TSX Capped Materials ETF, the four largest positions are Agnico Eagle at 12.99%, Barrick at 10.95%, Wheaton Precious Metals at 8.80% and Franco-Nevada at 7.23%. Adding the gold and silver names through the top twenty gives roughly 58% of the sector, and that is a floor, since the fund holds 63 positions.

Multiply through and gold alone is close to 11% of the entire Canadian equity market. Agnico Eagle now sits ninth in the index, ahead of Brookfield. An investor who bought the Canadian market in 2019 and holds it today owns a materially larger gold position than the one they chose.

Now look at what the product shelf actually contains

Across the four largest Canadian issuers of covered call ETFs, BMO, Hamilton, Harvest and Global X Canada, the funds built on Canadian underlyings cover a short list of sectors: banks, diversified dividend payers, utilities, telecoms, oil and gas, and the broad TSX 60.

Global X Canada is the cleanest illustration. It runs more than five billion Canadian dollars across covered call and premium yield funds. Its Canadian sector products are banks, telecoms, and oil and gas. Three sectors. Everything else in its equity range points at the S&P 500, the Nasdaq-100, the Russell 2000, developed international, emerging markets, or metals.

That is the index reproduced as a catalogue.

The test that settles it

A pattern is only interesting if you have tried to break it. So here is the falsification test: does a Canadian covered call ETF on domestic technology or domestic health care exist anywhere?

Across those four issuers and well over a hundred covered call products, there is not one.

The funds that do cover those sectors are built entirely on American companies. Hamilton's healthcare covered call fund holds Amgen, AbbVie, Thermo Fisher, Vertex, Merck, Bristol-Myers, Eli Lilly, Johnson & Johnson, Danaher and Abbott. Not a single Canadian name. Its technology fund holds Palantir, Micron, Microsoft, AMD and Apple, carries close to a billion dollars, and gives unhedged Canadian dollar exposure to American tech. Harvest runs the same pair with the same answer.

CI names its two funds Health Care Giants Covered Call and Tech Giants Covered Call. The word giants is the admission: there are no Canadian giants in those sectors, so the product is assembled abroad and sold at home.

The single-stock funds prove it twice

Harvest runs roughly thirty-five single-stock covered call ETFs, each writing calls on one company. Twenty-five are built on American companies. Ten are built on Canadian ones.

The ten Canadian names: Royal Bank, TD, TELUS, BCE, Canadian Natural, Enbridge, Suncor, Cameco, Agnico Eagle and Shopify. Nine of those ten are banks, telecoms, energy or mining. Shopify is the only Canadian company outside those four industries large and liquid enough to support an options-based product.

The twenty-five American names are overwhelmingly technology, health care and financial technology. Two lists, two different economies.

Why managers cannot simply build Canadian versions

Two constraints bind, and they compound.

The first is that there is nothing to build on. A sector covered call fund needs enough names to spread across without becoming a bet on one company. Canadian health care is 0.29% of the index. Canadian technology is 8%, and a large share of that is Shopify, Constellation Software and CGI. You cannot construct a diversified twenty-stock health care portfolio from a market that barely has a health care sector.

The second is that the options themselves have to trade. This is the constraint most commentary misses. A covered call ETF does not merely own stocks. It writes options on them every month, at scale, and has to roll those positions without moving the market against itself. That requires open interest, tight spreads and depth at multiple strikes.

The Montreal Exchange lists options on roughly 380 Canadian stocks. In the first ten months of 2025 it traded about 194 million contracts across its entire derivatives complex, a figure that includes interest rate futures rather than equity options alone. The American options market traded about 13.8 billion contracts in 2025, averaging 59 million a day.

Even taking the Canadian figure at face value and annualising it, the American market is close to sixty times larger, and the gap on single-stock equity options specifically is wider still. Within those 380 optionable Canadian names, the subset with enough consistent open interest to support a systematic monthly overwrite programme is far smaller. You can read that subset directly off Harvest's shelf: it is ten companies.

What this means when you actually pick a fund

Three consequences follow, and none of them show up in a yield ranking.

A Canadian covered call portfolio is a concentrated bet unless you deliberately make it otherwise. Holding a Canadian bank fund, a Canadian dividend fund and a Canadian oil and gas fund is not diversification. All three sit inside the same 70% of the index, and they fell together in every drawdown that index has had.

The American funds listed in Canada are not a different asset class from the American funds listed in New York. A Canadian dollar Nasdaq-100 covered call ETF and an American one write the same options on the same companies. What differs is the currency wrapper and the fee, not the exposure. If you already hold American covered call funds, adding the Canadian listed version adds nothing but a line on your statement.

Currency hedging is a separate decision, and it is usually made by accident. These products come in hedged and unhedged versions, BMO's ZWH against ZWS, Hamilton's SMAX against SMAX.U. The choice between them has nothing to do with the covered call strategy and everything to do with whether you want a second, uncompensated bet on the Canadian dollar sitting on top of your income. Most fund lists never mention it.

What this article does not establish

Everything above concerns supply. It shows that the Canadian covered call shelf mirrors the index, and that issuers reach into the United States for the sectors Canada lacks and for the options depth Canada cannot provide.

It does not show where the money goes. Whether Canadian investors actually allocate more to the American-exposed products than to the domestic ones is a question about flows, and we have not measured it. Some of the largest and fastest-growing funds in the category are domestic, which suggests the answer is less obvious than the catalogue makes it look.

The short version

Canada has a deep options market in exactly four industries, because those are the four industries Canada has. Every covered call product built on Canadian underlyings lives inside that boundary. Everything beyond it, technology, health care, broad American exposure, has to be imported, and the industry imports it in Canadian dollars so that it looks domestic on a brokerage statement.

The fund is Canadian. The risk usually is not.
