ASSET LOCATION — CANADA
RRSP and TFSA: asset location mechanics
Same placement principle as before — but one cross-border quirk changes which wrapper actually keeps more.
Two registered wrappers, two different deals
An RRSP and a TFSA are both registered accounts, but they're built around opposite tax mechanics. Contributions to an RRSP are generally deducted from taxable income in the year they're made, growth inside the account isn't taxed while it stays there, and withdrawals are taxed as ordinary income when they eventually come out. A TFSA works the other way: contributions aren't deducted from income at all, but growth inside the account and withdrawals are not taxed.
​
Both are “tax-sheltered” in the broad sense used in the asset-location principle covered on the main asset-location page — holdings that generate more taxable income in a given year generally sit more efficiently inside either one than in a non-registered account. Where it gets more specific is a quirk that applies to only one of the two.
The withholding-tax quirk that changes things
Under the Canada-U.S. tax treaty, U.S.-listed dividend-paying holdings held directly inside an RRSP are generally exempt from the U.S. non-resident withholding tax that would otherwise apply. That exemption does not extend to a TFSA — the CRA does not recognize a TFSA as a retirement account for treaty purposes, so U.S. dividends paid into a TFSA generally have the withholding tax deducted at source, and because a TFSA is a registered account, there's no foreign tax credit mechanism available to reclaim it on a Canadian return.
​
The practical effect: for the same U.S. dividend-paying ETF or stock, a dollar of dividend income can come out ahead inside an RRSP compared to inside a TFSA, purely because of where the withholding tax bites. This is one of the few cases where the general “TFSA is the more tax-advantaged account” intuition doesn't automatically hold once foreign withholding enters the picture.
Why it's easy to miss
It's a common assumption that a TFSA is simply the “better” registered account because withdrawals are never taxed, so it should hold whatever is expected to grow fastest. But for U.S.-dividend-paying holdings specifically, the withholding-tax treaty exemption only applies inside an RRSP. Self-directed investors sometimes place their U.S. dividend ETFs in a TFSA by default and only later notice the withholding tax being deducted from each distribution.
Contribution room works differently also.
Beyond the withholding-tax quirk, the two accounts differ in a way that matters for how easily a location decision can be undone later. RRSP contribution room, once used, is not restored by a later withdrawal — taking money out (outside of specific programs meant for home purchases or education) is treated as taxable income and doesn't free up new room. TFSA contribution room is different: an amount withdrawn is added back to available room, generally starting the following calendar year.
​
This affects how reversible an asset-location choice is. Moving a holding out of a TFSA can generally be undone later without a permanent room cost. Moving a holding out of an RRSP is a taxable event and a permanent use of that contribution room, which is a reason self-directed investors often treat RRSP placement as a longer-term decision than TFSA placement.
Where the two accounts compare

NOTE: treaty withholding-tax treatment, contribution-room mechanics, and any program-specific exceptions (e.g. home-purchase or education withdrawal plans) could change, confirmed against current CRA guidelines.
How this tends to factor into placement
Putting the pieces together, self-directed investors weighing RRSP versus TFSA placement are generally weighing at least three things at once: the tax treatment of contributions and withdrawals, whether a holding pays U.S.-source dividends, and how reversible the placement needs to be. None of these changes the overall stock/bond/cash mix decided on the main asset-location page — it only affects which registered wrapper a given holding tends to sit more efficiently inside.
​
A non-registered margin or cash account remains part of this picture too: foreign dividend withholding still applies there, but because it's not a registered account, a foreign tax credit can generally be claimed on a Canadian tax return to offset it — a third possible outcome alongside the RRSP exemption and the TFSA's non-reclaimable withholding.
