VOO vs ITOT, why yield and returns differ
Sector mix explains much of the gapThe S&P 500 fund holds about 500 large companies; the total market fund adds thousands of small and mid-sized stocks. Because large companies make up most of the total market by weight, the two move together, and the differences in return come from the small-company slice and from the fee. Over the periods to Sep 30, 2026 the S&P 500 funds led slightly over 5 and 10 years. That is one window, not a rule: small companies lead in some years.

VOO vs ITOT for Canadian investors
Currency, withholding tax and account typeVOO and ITOT are U.S.-listed and trade in U.S. dollars, so buying them from a Canadian account usually involves converting Canadian dollars, which adds a cost on both entry and exit. Currency moves also change your return in Canadian dollars even if the funds are flat in U.S. dollars.
U.S. dividends paid to Canadian residents can be subject to U.S. withholding tax, generally 15% under the Canada-U.S. tax treaty. An RRSP is generally exempt from that withholding on U.S. dividends, while a TFSA is not; in a taxable account the withheld amount may be claimable through the foreign tax credit. Both funds have low yields, so the withholding in dollar terms is small on a given balance.

Risks of VOO and ITOT
What can go wrongShared risks
- Both hold U.S. stocks and can fall with the market; the S&P 500 lost about 18% in 2022 and the total market about 19.5%.
- Both are heavily weighted to a handful of technology and internet companies, so a decline in those names moves both funds.

Fund-specific risks

General education, not tax adviceBoth funds invest in U.S. stocks and pay quarterly dividends. Broad index funds usually distribute few capital gains.
