If you are a newer investor using one of Canada’s commission-free brokerages—like Wealthsimple—you may have been confused the first time you searched for a major U.S. stock. For example, a search for Microsoft (MSFT) can show the NASDAQ-listed share (trading around US$416 per share as of May 8, 2026) and multiple Canadian alternatives such as the CIBC Microsoft CDR CAD Hedged and the BMO Microsoft CDR (ticker ZMSF).
Those Canadian-listed alternatives are Canadian depositary receipts (CDRs). In short, CDRs give Canadian investors exposure to U.S. (and international) equities priced and settled in Canadian dollars, typically with an embedded currency hedge. They pass through the underlying stock’s price movements and dividend payments, although dividends remain subject to the standard 15% U.S. withholding tax when applicable.
CDRs can be attractive for several practical reasons. A single share of Microsoft trades for hundreds of U.S. dollars, while a CDR share can trade for a much lower Canadian-dollar amount—making it easier for investors without fractional-share access or those who prefer transacting entirely in CAD to buy individual names. If your broker charges higher fees for trading U.S.-listed stocks, a CDR can also reduce transaction costs.
However, that convenience is not free. The embedded currency hedge has a cost—typically in the neighborhood of 0.6% to 0.8% annually depending on the issuer—and those costs compound over time. That raises a practical question for Canadian investors: historically, how closely have CDRs tracked their underlying U.S. stocks after accounting for hedging costs and withholding taxes? Understanding the size and sources of that tracking error helps determine when a CDR is a sensible choice and when direct ownership of the U.S. share might be preferable.
Quantifying CDR tracking error versus U.S. stocks
To explore this, I back-tested two established blue-chip CDRs against their underlying U.S. shares, focusing on two contrasting cases:
- a dividend-paying company, where the CDR investor faces both the currency-hedge cost and the 15% U.S. dividend withholding tax, and
- a company that pays little or no dividend, to isolate the effect of the currency hedge and structural frictions.
All data came from PortfolioVisualizer using the longest common return periods available for each pair. Returns shown are net of management costs but before taxes, brokerage commissions, or implicit trading frictions like bid-ask spreads.
The first comparison looked at The Coca-Cola Company (KO) versus the CIBC Coca-Cola CDR (COLA). From January 2023 through April 2026, Coca-Cola shares compounded at an annualized 9.76% with dividends reinvested, while the COLA CDR returned 8.14% annualized—a gap of 1.62% per year.

Breaking down the likely sources of that 1.62% gap: using the higher end of typical issuer estimates (about 0.6% for the currency-hedging cost) and adding back that amount to the CDR’s return raises it to roughly 8.74%. Then apply the 15% withholding tax to Coca-Cola’s trailing five-year average dividend yield of 2.89% (as of May 8, 2026), which produces a further drag of about 0.43%. Together those two factors explain about 1.03% of the shortfall. The remaining 0.59% suggests additional implementation frictions or other costs within the CDR structure.
For a non-dividend example, I compared Amazon (which historically pays little to no dividend) and its CAD-hedged CDR over a shorter period (January 2026 through April 2026). The CDR still underperformed, though the gap narrowed to about 0.99%—largely isolating the currency-hedge cost and other structural differences.

These examples reinforce two key points. First, dividend withholding is a meaningful source of underperformance for CDRs of higher-yielding U.S. stocks. Second, the stated currency-hedging spread does not always fully explain the observed tracking error—there often appears to be an additional structural drag on the order of a few tenths of a percent annually.
That does not make CDRs inherently poor products. They provide a legitimate convenience: CAD pricing, single-currency settlement, and simplified record-keeping for accounts held in Canada. But convenience typically comes at a cost, and over long holding periods those costs can make owning the U.S. share directly more efficient for many investors.
When CDRs might still be worth it
My general preference for broad U.S. equity exposure is low-cost index ETFs, including hedged ETF options for those who want currency protection. For investors focused on individual stocks, however, CDRs can be practical depending on the broker and account type.
Consider Wealthsimple as a concrete example. Wealthsimple advertises commission-free trading, but its foreign exchange conversions are relatively expensive: a 1.5% currency conversion fee is added on top of the platform’s corporate exchange rate when converting CAD to USD or vice versa. That fee applies when you buy U.S. stocks and again when you sell, and dividends paid in USD are converted back to CAD unless you maintain a U.S.-dollar account. Those multiple conversion events can create meaningful cumulative drag.
Wealthsimple offers U.S.-dollar accounts, but access is limited: Premium clients with at least $100,000 in assets or those who pay a separate $10 monthly subscription can enable one. When enabled, Wealthsimple’s conversion fees fall on a tiered schedule (conversions under $10,000 at 1.5%, $10,000–$34,999.99 at 1.0%, $35,000–$99,999.99 at 0.5%, and 0% above $100,000). For many retail investors who trade smaller amounts and do not have a U.S.-dollar account, repeated FX conversions make direct ownership of U.S. shares relatively costly.
By contrast, Interactive Brokers presents a very different cost profile. IBKR’s commission and FX schedule is far cheaper for frequent or larger trades: U.S. stock commissions can be as low as US$0.0035 per share and currency conversion costs are often a small flat amount (for example, a minimum of US$2 per conversion or a tiny basis-point spread). Using a CAD$10,000 example, converting at Wealthsimple could cost roughly $150 in fees, whereas the equivalent cost at a low-cost brokerage like Interactive Brokers would typically be a few dollars—far less over long holding periods.
So when does a CDR make sense? If you hold assets in a Tax-Free Savings Account (TFSA), where U.S. dividend withholding still applies whether you own the U.S. share or a CDR, and you’re on a brokerage platform with high FX fees, the simplicity of buying a CAD-hedged CDR can be attractive—especially for shorter holding horizons. Conversely, if you hold U.S. shares inside an RRSP (where the Canada–U.S. tax treaty generally exempts U.S. withholding on dividends) and you have access to a low-cost broker or a U.S.-dollar account, direct ownership of the U.S. stock usually makes more sense.
In short: CDRs are a useful tool for Canadian investors who value convenience or face high FX costs, but they are not a perfect substitute for direct ownership. Understand the hedging fees and tax implications and compare them with your broker’s FX and trading costs before deciding which route fits your goals.
