Does the RRSP have protection the TFSA does not?

Yes. The RRSP regime contains a business income exemption under paragraph 146(4)(b) that exempts an RRSP trust from tax on business income from qualified investments. The TFSA regime has no equivalent — subsection 146.2(6) taxes a TFSA carrying on a business.

Can you trade spreads in an RRSP?

No. An RRSP is structurally a cash account and cannot use margin. A spread contains a short leg requiring collateral, so it cannot be placed in an RRSP regardless of your options approval level.

Are US dividends taxed differently in an RRSP?

Under the Canada-US tax treaty, US dividends paid into an RRSP are generally exempt from the 15% withholding tax that applies to a TFSA. The treatment of option premium is a separate question and worth confirming with an accountant.

Can you sell covered calls in an RRSP?

Q: Can you sell covered calls in an RRSP in Canada?

Yes. Covered calls are permitted in an RRSP because the shares you already own back the obligation, so no margin is required. Confirm your specific approval level with your broker.

Q: Was the RRSP-TFSA difference ever tested in court?

Yes. In Ahamed v The King, 2023 TCC 17, the taxpayer argued the two regimes are mirror images so the RRSP exemption should be read into the TFSA rules. The Tax Court disagreed and the Federal Court of Appeal affirmed in Canadian Western Trust Company v The King, 2024 FCA 108.

Yes. Covered calls are permitted in an RRSP — the shares you already own back the obligation, so no margin is involved.

And there is something the RRSP has that the TFSA does not: a business income exemption written into the RRSP regime. That difference has been tested in court, and it stands.

The asymmetry between the two accounts

RRSPs and TFSAs feel similar. Both are registered, both shelter growth, both are structurally cash accounts, both rule out the same strategies. It is natural to assume they are treated the same way for tax.

They are not.

Account	Business income exemption
RRSP	Yes — paragraph 146(4)(b) exempts an RRSP trust from tax on business income from qualified investments
TFSA	No — subsection 146.2(6) taxes a TFSA carrying on a business, with no equivalent carve-out

This was argued and lost

In Ahamed v The King, 2023 TCC 17, the taxpayer's central argument was exactly this asymmetry. He contended that the RRSP and TFSA regimes are "mirror images" of each other, so the RRSP exemption should be read into the TFSA rules.

The Tax Court disagreed, and the Federal Court of Appeal affirmed in Canadian Western Trust Company v The King, 2024 FCA 108. The courts conducted a textual, contextual and purposive analysis and found the phrase "carries on one or more businesses" in subsection 146.2(6) clear and broad enough to capture all businesses.

Reading the exemption across would have meant rewriting legislation Parliament actually passed. The court declined.

So the asymmetry is not an oversight to be argued around. It has been tested at two levels and it holds.

What that means practically

For systematic, repeated option writing, the RRSP does not carry the same statutory exposure to the carrying-on-a-business question that a TFSA does.

That is a real difference and it is worth knowing. It is also only one input among several.

This is not a recommendation to move your options activity into an RRSP. The two accounts differ in contribution room, withdrawal treatment, whether the shelter is a deferral or an exemption, and what the money is ultimately for. Statutory exposure to one question is not the whole decision — and it is a conversation for your accountant, not an article.

What still limits you in an RRSP

The exemption addresses tax treatment. It does nothing about account structure, which is identical to a TFSA:

Strategy	Permitted in an RRSP?
Covered calls	Yes
Protective puts	Yes
Buying calls and puts	Yes
Cash-secured puts	Broker dependent
Any spread	No — requires margin
Naked writing	No

An RRSP is a cash account. It cannot use margin or short. A spread contains a short leg needing collateral, so it cannot exist there regardless of your options approval level.

Two things specific to RRSPs

US withholding tax

Under the Canada–US tax treaty, US dividends paid into an RRSP are generally exempt from the 15% withholding that applies to a TFSA. That is an RRSP advantage on dividend-paying US shares — and relevant if you are writing covered calls against them.

The treatment of option premium specifically is a separate question from dividends. Ask your accountant rather than assuming it follows.

No RESP or LIRA options at some brokers

Not every registered account type supports options at every broker. RRSPs and TFSAs generally do; RESPs, LIRAs and RRIFs frequently do not, or do so with tighter restrictions.

The one question to ask your broker

"Can I sell covered calls and cash-secured puts in my RRSP, and what option level do I need?"

Four minutes on the phone settles it definitively. Policies differ between brokers and change over time, so no article — including this one — should be your final source on what your specific account permits.

What to do

Confirm with your broker what your RRSP actually permits and at what approval level.
Look up assignment and exercise fees. Run any income strategy and you will be assigned regularly — that is the strategy working, not failing, but the fees add up.
Speak to your accountant about which account should hold what. The statutory difference above is real, and it is one factor in a decision that depends on facts specific to you.
