DeFi transactions and Canadian tax: the open questions

Where CRA stands

CRA’s crypto-asset guidance set (landing page modified 2025-10-29) covers definitions, dispositions, business versus capital treatment, mining and centralized-platform staking, records and GST/HST. When we checked every page on 2026-10-30, none addressed DeFi: no lending, borrowing, liquidity pools, wrapped tokens or bridges.

That does not mean DeFi is untaxed. CRA’s general rules still apply to whatever you actually do. It lists trading one crypto-asset for another as a disposition, and it lists rewards as a way of acquiring crypto-assets. The hard part is deciding how those general rules fit actions that did not exist when the rules were written.

This page does not give you answers, because CRA has not given them. It gives you the questions a tax professional is likely to ask, and the records you will need to answer them.

Action by action: what happens and what to ask

Lending, borrowing and liquidation

Lending protocols usually hand you a receipt token when you deposit. If you see that as trading one crypto-asset for another, CRA’s general rule points toward a disposition. If you see it as a claim on the same tokens you deposited, it may look more like keeping your property. The design of the specific contract matters, and so does whether you can withdraw exactly what you put in.

Borrowing raises different questions. Taking a loan is not usually income, but DeFi loans are collateralized by tokens locked in a contract. If the value of your collateral falls far enough, the protocol can liquidate it, selling part of it automatically. That looks a lot like a sale, but CRA has not addressed DeFi liquidations specifically. See liquidation risk for how liquidations work.

Borrowing to buy more crypto-assets also touches one of CRA’s listed business-income indicators, financing purchases with debt. Raise it with your adviser when discussing capital vs business income.

Liquidity pools, fees and reward tokens

Adding liquidity means depositing two tokens and receiving an LP token. When you withdraw, you rarely get back the same amounts you put in, because the pool rebalances as people trade. That is the mechanism behind impermanent loss, and it makes the tax picture harder: the tokens coming out are a different mix from the tokens that went in.

Trading fees usually accumulate inside your pool share rather than arriving as separate payments. Reward tokens, by contrast, often arrive separately and can be claimed at a time you choose. Each design raises its own timing question. When is income earned, if at all, and what cost does each unit carry?

Wrapping, bridging and airdrops

Wrapping and bridging both give you a token that is meant to track another one. The key question is whether you still own the same property or now own a different one, such as a claim on a contract or on a bridge’s reserves. That distinction matters for whether a disposition happened, and later for the superficial loss rule, which depends on whether property is “identical.”

Airdrops vary widely. Some arrive unasked, some reward past use of a protocol, and some require you to complete tasks. Those facts can affect the answer, which is why a tax professional will ask how you came to receive the tokens. Whatever the treatment, record the date, units and Canadian-dollar value when they arrived.

Questions a tax professional will ask you

Expect these questions, and have the answers ready before your appointment:

• Which wallets and addresses are yours, and which platforms did you use?
• For each action, what did you give up and what did you receive?
• Could you withdraw exactly the same units you deposited, or a different amount or token?
• What was the Canadian-dollar value of each side at the time, and what price source did you use?
• How often did you transact, and did you borrow to buy crypto-assets?
• Which rewards, fees or airdrops did you receive, and when did you claim them?
• What gas or network fees did you pay, and on which transactions?
• Have you treated similar transactions a particular way in earlier years?

Records to keep for DeFi

CRA’s records page (modified 2025-11-10) asks for the units, type, date and time, Canadian-dollar value, nature of the transaction and the other party, which may be only a crypto-asset address. For DeFi, add the details that let someone reconstruct each step later:

• The transaction ID for every deposit, withdrawal, claim, swap, wrap and bridge.
• The smart contract address you interacted with, and a plain description of what it does.
• Receipt, LP and wrapped token amounts received and returned.
• Network fees paid in each transaction.
• A dated note explaining the treatment you and your adviser chose, and why.

Use the record keeper to capture these as you go, and the tax event classifier to flag which actions need discussion.

Your checklist

• List every wallet address and protocol category you used this year.
• Save transaction IDs for each deposit, withdrawal, claim, wrap and bridge.
• Record Canadian-dollar values for both sides of every step.
• Track receipt, LP and wrapped token units in and out.
• Write down the treatment you chose with your adviser, and apply it consistently.
• Check CRA’s crypto-asset pages for new guidance before you file.
