Is My Portfolio Too Canadian? Home Bias in Banks and Energy
Canada is under 3% of the world’s stock market, but many Canadian portfolios are half Canadian or more. Here is what that concentration looks like by sector, how it behaved in crashes, and reference points for the Canada/US split.
Key takeaways
- Financials, materials and energy were 69% of the S&P/TSX Composite on Sep 30, 2026 (TSX data). A portfolio that is mostly Canadian is mostly those three sectors.
- Canada was 2.89% of the MSCI ACWI global index on Oct 9, 2026 (iShares). Vanguard’s all-equity ETF portfolio held 29.6% in Canada on Jun 30, 2026: a deliberate home tilt, far below what many Canadians hold.
- Canadian stocks did not protect against US crashes. In Exent’s data, the iShares MSCI Canada ETF fell 62.1% in 2007–09 and 42.7% in 2020, more than the S&P 500.
- There is no correct split, but checking your sector weights across all accounts is the first step.
Is my portfolio too concentrated in Canadian banks and energy?
If most of your stocks are Canadian, probably yes, because the Canadian market itself is concentrated. On September 30, 2026, three sectors made up 69% of the S&P/TSX Composite index, according to the TSX Daily Trading Report:
| S&P/TSX Composite sector, Sep 30, 2026 | Weight |
|---|---|
| Financials (banks, insurers, asset managers) | 34.41% |
| Materials (miners, gold, fertilizer) | 18.38% |
| Energy (oil, gas, pipelines) | 16.26% |
| Industrials | 10.16% |
| Information technology | 8.60% |
| Utilities, consumer, telecom, real estate and health care combined | 12.19% |
Health care, a large part of the US market, was just 0.32% of the index. A Canadian-heavy portfolio is a bet on interest rates, commodity prices and the domestic economy, whether or not that was the plan.
What does home bias look like in dollars?
Illustrative: a C$1,000,000 portfolio with 60% in Canadian stocks spread like the index, and 40% in a US index fund.
| Exposure | Share of Canadian stocks | Dollars | Share of whole portfolio |
|---|---|---|---|
| Canadian financials | 34.4% | C$206,460 | 20.6% |
| Canadian materials | 18.4% | C$110,280 | 11.0% |
| Canadian energy | 16.3% | C$97,560 | 9.8% |
| Three sectors together | 69.1% | C$414,300 | 41.4% |
Many real portfolios are more concentrated than the index: the big banks, a pipeline, a couple of oil producers and a telecom. The big Canadian banks tend to move together, because they share the same housing market, rate cycle and regulator. Owning five of them is closer to one large position than to five independent ones. More on why in concentration vs diversification.
Did Canadian stocks hold up better in crashes?
Not in the big ones. Peak-to-trough declines from Exent’s data, as of Sep 30, 2026, for the iShares MSCI Canada ETF (EWC) and the S&P 500 (SPY), both in US dollars:
| Crisis | Canada (EWC) | S&P 500 (SPY) |
|---|---|---|
| Global financial crisis, 2007–09 | −62.1% | −56.5% |
| COVID crash, 2020 | −42.7% | −34.1% |
| Inflation bear market, 2022 | −25.4% | −25.4% |
| Tariff selloff, 2025 | −12.0% | −19.0% |
Over the 60 months to September 2026, EWC’s correlation with SPY was 0.82, so the two markets usually moved together. Over the 10 years to September 30, 2026, EWC compounded at 10.8% a year against 15.2% for SPY, in US dollars. Past results, not a forecast: Canada has led in other decades, and 2025 shows it can hold up better in some selloffs. See US vs international returns by decade.
How much of my portfolio should be in Canadian vs US stocks?
There is no single right answer, but there are useful reference points. The global market weight is the neutral starting point; widely used Canadian one-ticket portfolios hold more Canada on purpose, for currency, tax and familiarity reasons.
| Reference point | Canada | United States | Source, date |
|---|---|---|---|
| Global stock market (MSCI ACWI) | 2.89% | 64.62% | iShares ACWI, Oct 9, 2026 |
| Vanguard All-Equity ETF Portfolio (VEQT) | 29.6% | 45.3% | Vanguard, Jun 30, 2026 |
| A portfolio of only Canadian stocks | 100% | 0% |

Reasons Canadians tilt home: no currency risk on money spent in Canadian dollars, the dividend tax credit on eligible Canadian dividends in taxable accounts, and no US withholding or estate-tax questions. Reasons to tilt less: sector concentration, a small market, and the fact that your job, home and pension may already depend on the Canadian economy.
Common mistakes when cutting home bias
- Counting only one account. A global ETF in the RRSP next to a TFSA full of banks and pipelines still adds up to a Canadian-heavy portfolio.
- Swapping one concentration for another. Moving from Canadian banks into a handful of US tech stocks trades a sector bet for a different one. The S&P 500 index has its own concentration in its largest companies.
- Selling in a taxable account without counting the tax. Realizing large gains to diversify can cost more than the concentration risk it removes in the short run. Rebalancing with new money is one alternative.
- Ignoring currency. Adding US stocks adds US-dollar exposure; see hedged vs unhedged ETFs.
What should I check this weekend?
- Add up every account (TFSA, RRSP, non-registered, workplace plan) and calculate the Canadian share of your stocks.
- Calculate the share in financials, energy and materials across everything, including what your Canadian ETFs hold.
- List your five largest Canadian positions. If several are banks, treat them as one bet when you size it.
- Look at what your job, pension and home already depend on. A bank employee with bank stocks has doubled up.
- If you add US or international stocks, check the account first: withholding tax and currency costs differ by account.
Account placement for US holdings is covered in US dividend withholding tax for Canadians, and the wider checks in the guide for Canadian investors.
How to measure your home bias with Exent
- Upload a screenshot or file from each account at Wealthsimple, Questrade or your bank broker (CSV, Excel, PDF or Google Sheet); no brokerage login.
- Exent reads TSX listings with their .TO suffix and shows concentration and your largest positions across all accounts. It does not look inside ETFs, so a fund’s sector mix still comes from its fact sheet.
- Correlation clusters show which holdings, such as several bank stocks, move as one; the what‑if simulator shows how a different Canada/US split would change crash losses.
Frequently asked questions
Home bias is holding a much larger share of your own country’s stocks than its share of the global market. Canada was 2.89% of the MSCI ACWI index on Oct 9, 2026, while many Canadians hold half or more of their stocks at home.
Financials were 34.41% of the S&P/TSX Composite on Sep 30, 2026, according to the TSX Daily Trading Report. Materials were 18.38% and energy 16.26%.
Vanguard’s All-Equity ETF Portfolio held 29.6% in Canadian equity on Jun 30, 2026, with 45.3% in US, 17.9% in developed international and 7.1% in emerging-market equity.
Only partly. In Exent’s data the iShares MSCI Canada ETF had a 0.82 correlation with the S&P 500 over five years and fell more than the S&P 500 in 2008 and 2020, though less in the 2025 selloff.
It is a concentrated bet. The big banks share the same housing market, interest-rate cycle and regulator, so they tend to fall together. Whether that risk suits you depends on the rest of your finances.
