Blockchain Payments for Canadian Merchants: Start Here

Your path through the portal

Key points

Start with your own numbers: volume, average sale and the share of customers outside Canada.
Lower processing cost is only one line; refunds, conversion, records and staff time count too.
There are no chargebacks on-chain, which cuts dispute costs and removes the customer's safety net.
Accepting payment solely for your own goods or services is listed by FINTRAC as an MSB exclusion, but the word solely matters.

The questions merchants usually need answered

What would it cost me, all in? Not just the percentage fee, but conversion, off-ramp, network fees, float and dispute costs.
Would my customers use it? Nobody can answer this from a spreadsheet; only a small pilot can.
What changes at the counter or checkout? Quotes, confirmations, refunds and what staff do when something goes wrong.
Do I have new regulatory obligations? FINTRAC, GST/HST and record-keeping.
How does my bookkeeper record it? Fair market value in Canadian dollars at the time of each sale.

Your workflow, in order

Then read the two compliance pages that matter most to a merchant: FINTRAC MSB registration and GST/HST on crypto payments.

Worked example: a small retailer

Suppose a retailer takes $40,000 a month, averages $60 a sale and sells 10% of its volume to customers outside Canada. Using the site's illustrative default rail assumptions (not market data), each rail carrying the full month would cost roughly:

Card: about $1,543 (3.86%), including about $203 of expected dispute cost.
EFT: about $689 (1.72%), with the $4,000 cross-border share falling back to card.
Stablecoin to a self-hosted wallet: about $633 (1.58%), mostly the 1% USD-to-CAD conversion and 0.5% off-ramp.
Crypto-asset through a processor: about $1,700 (4.25%), because a $1.50 network fee on a $60 sale adds up.

Disputes on their own

With about 667 card sales a month, a 0.5% dispute rate, a $25 fee, 60% of disputed sales lost and 30 minutes of staff time at $40 an hour, disputes cost roughly $270 a month, about $3,242 a year.

Reading the example honestly

A stablecoin option only saves money on the sales that actually move to it. If one sale in twenty moves, you save on that sale, not on the other nineteen. The scenario builder lets you set that share and see the difference.

The model also leaves out costs that are real but specific to you: staff training, time spent on exceptions, accounting work and any provider's monthly fees. Add them before you decide anything.

Check your current card costs too. Under agreements with Visa and Mastercard, credit card interchange for eligible small businesses dropped from October 19, 2024: the annual weighted average for in-store domestic consumer credit transactions fell to 0.95% and online rates fell by 10 basis points, for businesses under $300,000 in annual Visa volume or $175,000 in Mastercard volume. Interchange is only part of what you pay, so ask your processor whether you received the reduction. Stablecoins vs cards for merchants walks through the trade-offs.

Pitfalls merchants run into

Holding by accident: if you do not convert promptly, you carry price risk. A stablecoin tracks its reference currency, such as the US dollar, which is still not the Canadian dollar.
No refund policy: without a chargeback system you need written rules on refund amounts, addresses and network fees.
Exceptions at the till: underpayments, overpayments and payments on the wrong network need a script staff can follow.
Keys on one person's phone: a self-hosted wallet means your business is responsible for key security and recovery.
Assuming PCI DSS no longer applies: it still covers your card acceptance. There is simply no PCI equivalent on the crypto side.

Compliance in one paragraph

FINTRAC lists an exclusion from money services business status for a business that solely accepts payment for goods or services it supplied to its own customer. If you also take payments on behalf of others, such as other vendors at a market or a marketplace, check with FINTRAC. For tax, the CRA treats paying with crypto like a barter transaction: include the fair market value in Canadian dollars in income, and if you are a GST/HST registrant, calculate GST/HST on that value at the time of the sale. These rules are as of October 30, 2026.

Questions people ask

Will accepting stablecoins lower my overall fees?

Only on the sales that move to it, and only after conversion and off-ramp costs. Run your real numbers through the scenario builder before assuming a saving.

Do I need special equipment?

Not necessarily; payment requests can be shown as a QR code. You do need a plan for keys, confirmations and refunds, which matters more than hardware.

What happens if a customer wants a refund?

You send a new outbound payment; there is no chargeback mechanism. Decide in advance whether refunds are fixed in Canadian dollars or in units of the asset.

Do I need to register with FINTRAC to accept crypto at my store?

FINTRAC excludes a business that solely accepts payment for goods or services it supplied to its own customer. If you also handle payments for others, read FINTRAC's MSB guidance or ask FINTRAC directly.
