How Are My Cryptocurrency Gains Taxed in Canada?
Cryptocurrency is treated as a commodity rather than as money, which means every time you dispose of it you have a taxable event — including when you trade one coin for another and never touch a dollar. Whether the result is a capital gain or business income is the question that decides how much you keep.
- The answer:: Because crypto is a commodity, disposing of it — selling, trading, spending, or gifting — is a disposition. Trading one coin for another is two events, not zero.
- The trap:: Assuming nothing is owed until you cash out to dollars. A year of active trading between coins can generate a substantial tax bill with no fiat ever leaving the exchange.
- The recommendation:: Keep records from the first transaction, not from the year you sell. The CRA expects the adjusted cost base of every holding, and reconstructing it years later from an exchange you no longer use is the hardest part of this.
Where the AI summary above gets this wrong
"You only pay tax on crypto when you cash out to Canadian dollars."
That's surface-true. Here's what it misses:
- A trade is a disposition — Exchanging one cryptocurrency for another disposes of the first. The gain or loss is measured in Canadian dollars at that moment, whether or not any dollars change hands.
- Spending it is a disposition too — Using crypto to buy goods is treated as disposing of it at fair market value, so an ordinary purchase can crystallise a gain.
- Capital or business changes the amount — A capital gain is only partly included in income. Business income is fully included. The distinction turns on how you were operating, not on what you would prefer.
01 Why it is a commodity, not currency
The CRA treats cryptocurrency as a commodity for income tax purposes. That single classification produces almost every consequence that surprises people, because disposing of a commodity is a taxable event in a way that spending money is not.
So a disposition includes selling for dollars, trading for another coin, using it to pay for something, and giving it away. Each is measured in Canadian dollars at the time it happens, which is why a year of activity can produce a tax bill without a single withdrawal.

02 Capital gain or business income
If the activity is an investment, the result is a capital gain and only part of it is included in income. If it amounts to carrying on a business — frequent transactions, short holding periods, activity promoted as a business, borrowing to finance it — the result is business income, included in full.
The distinction is a question of fact rather than a choice, and it is decided on the whole picture rather than any one factor. It matters enormously: the same profit produces materially different tax depending on which side of the line it falls.

03 What the tax actually costs
Whichever character applies, the amount is driven by your marginal rate, which is why the same gain costs a high earner far more than someone in a low-income year. The calculator shows the marginal cost on a given amount.
The lever most people have is timing. A capital gain is realised when you choose to dispose, so a year with low other income is a cheaper year to sell in — the same reasoning that applies to any appreciated asset.
Shows: what a given amount of additional taxable income costs you in tax at your marginal rate, and what you keep. Ignores: provincial surtaxes, credits that phase out with income, and any effect on income-tested benefits.
04 The record-keeping problem
You need the adjusted cost base of every holding, in Canadian dollars, at the time of every acquisition and disposition. Exchanges close, accounts are lost, and transfers between wallets obscure the trail, so this is the part that becomes impossible if left too late.
Start from the first transaction rather than the first sale. The cost of reconstructing years of history usually exceeds the cost of recording it as you go, and an incomplete record tends to resolve against you.
Record-keeping is the obligation that decides how a review goes. The date, the time, the Canadian dollar value at that moment, the counterparty and the platform fee have to be kept for every transaction, including a swap of one token for another, because the Agency treats each of those as a separate disposition to be documented on its own. Whichever side of the line the activity falls on, the arithmetic that turns a gain into tax is the same one used everywhere else, and it is set out in the capital gains inclusion rate.

The failure I have seen most is not aggressive planning, it is record-keeping. Someone trades actively for three years across two exchanges, one of which shuts down, and then has to construct an adjusted cost base from screenshots. The tax was never the hard part; proving what it should have been was.
FAQ
Do I pay tax when I trade one cryptocurrency for another?
Yes. Trading one coin for another disposes of the first, and the gain or loss is measured in Canadian dollars at that moment. No fiat has to change hands for the event to be taxable.
Is crypto a capital gain or business income in Canada?
That turns on how you were operating, and it is a question of fact rather than a choice. Investment activity produces a capital gain, only partly included in income; activity amounting to carrying on a business produces business income, included in full.
What records does the CRA expect?
The adjusted cost base of every holding in Canadian dollars, with dates and amounts for every acquisition and disposition. Start from your first transaction — reconstructing the history later from exchanges you no longer use is the hardest part of the whole exercise.
