Gate.io taxes for a Canadian resident work like any other crypto: every sale, swap or purchase with crypto is a disposition, half of a capital gain is taxable, and you have to report it whether or not a slip arrives. Waiting for a form from the exchange is the wrong plan.
Why a missing slip proves nothing
Some exchanges issue Canadian slips and many don’t. A slip is a convenience. The reporting duty comes from the Income Tax Act, and the CRA’s crypto guidance says you must keep your own books and records. If the exchange hasn’t sent anything, your downloaded history is the record.
Check the exchange’s help pages for what it provides to Canadian users and if your account is still open to you. Availability of services by province can change, and the platform’s current notice is the place to confirm it. Download your history before anything about your access changes.
Downloading the history
Exchanges usually offer transaction history exports, often as CSV files, from an account or orders area. The names and locations change, so look at the Gate.io help pages for the current steps rather than trusting an old screenshot.
You will probably need several files. Trades are the obvious one, but deposits, withdrawals, transfers and any earn or reward history live in separate reports. Export a wide date range if the tool allows, and split by year if it doesn’t. Keep the original files untouched in a folder for each tax year.
Turning rows into gains
Convert each row into Canadian dollars at the time of the transaction, using one documented rate source. Then use the average cost method, which the CRA applies to identical crypto-assets. Say you hold 400 units with a total cost of $1,000, or $2.50 each, and you sell 100 for $400. The cost of that sale is $250, so the gain is $150 and $75 is taxable.
Swaps count too. Trading one coin for another is a sale of the first at its value that day and a purchase of the second at the same value. Fees reduce proceeds or add to cost. The capital gains tax calculator is a quick way to see the tax on a total.
A worked example with fees
Take a year with three events. In January you buy 300 units of a token for $600, plus a $3 fee, so the cost is $603. In April you buy 100 more for $250 and a $2 fee, for $252. The pool now holds 400 units at $855, or $2.1375 each.
In September you sell 250 units for $700 with a $4 fee. Proceeds are $696. Cost is 250 times $2.1375, which is $534.38. The gain is $161.62, and half of it, about $80.81, is added to income. What’s left is 150 units with a cost of $320.62.
Deposits from a bank account into the exchange aren’t taxable, and they help prove what you paid. Keep those statements next to the exports.
Where records tend to go missing
Old accounts are the usual gap. If you used another exchange or wallet before this one, the coins you deposited carry a cost from that earlier purchase, and you need it. Without it, the history starts mid-story.
Another gap is coins received from rewards, promotions or referrals. The CRA’s guidance on crypto covers income from some of these, valued in Canadian dollars when received. Look for them in a separate report, since they rarely appear in the trade file.
Finally, watch for coins that were renamed or moved to a new token after a change by the project. The export may show the old name in early rows and the new one later, so match them before you compute averages.
Foreign property reporting
If the total cost of your specified foreign property is above $100,000 CAD at any time in the year, you may need to file Form T1135. Cost is what counts here, not current value. Crypto held with a foreign exchange can fall under it depending on the facts, so read the CRA’s T1135 guide if your holdings are large.
Losses and the 30-day rule
If you sell at a loss and buy the same coin within 30 days before or after, and still hold it, the loss is superficial and denied for now. The amount is added to the cost base of the replacement. Otherwise, capital losses offset capital gains, with any excess carried back three years or forward without limit.
Check the income tax calculator once you have a net gain, since half of it joins your other income.
Keeping the paper trail
Keep the exports, your calculations and any notes for six years after the year they relate to. If a transaction is missing, look through bank records, emails and other wallets before estimating, and label any estimate clearly. Never enter a zero cost to close a gap, since that raises your taxable gain. Related tools: the Marginal Tax Rate & Tax Brackets calculator, plus all our tax calculators.
