Interchange Fees in Canada: What They Are, Who Sets Them, and What You Can’t Change
Interchange is the largest single component of most Canadian card processing bills, and the only one no processor can discount. Understanding it tells you exactly which part of your rate is actually negotiable.
What an interchange fee actually is
Interchange is the fee your processor pays to the bank that issued your customer’s card, on every single transaction. It is not your processor’s revenue. It is a wholesale cost they incur on your behalf and pass on to you, and it is set by Visa and Mastercard rather than by anybody you can telephone.
Three things follow from that, and they explain most of what is confusing about card pricing:
- Every processor in Canada pays the same interchange. It is identical at Moneris, Elavon, Square, Stripe and everyone else. Any claim to have secured cheaper interchange is false.
- It is not one rate but a large table. Visa and Mastercard each publish dozens of Canadian categories, varying by card type, business type, and how the card was presented.
- Your effective rate can move without your pricing changing. A shift in which cards your customers happen to use will move your bill on its own.
This is why interchange is the floor beneath your rate. The only number genuinely up for negotiation is what your processor adds on top of it.
What moves Canadian interchange rates up and down
The category a transaction lands in is decided automatically, at the moment of authorisation, by data you either did or did not send. These are the factors that decide it:
| Factor | Cheaper end | More expensive end |
|---|---|---|
| Card type | Standard consumer credit; Interac debit | Premium, rewards, business and corporate cards |
| How the card is presented | Tapped or inserted, card physically present | Keyed in, online, or card-not-present |
| Data sent with the transaction | Full AVS, 3-D Secure, Level 2 / Level 3 data | Missing or incomplete data fields |
| Settlement timing | Batch settled same day | Batch settled late |
| Business category | Programs exist for grocery, fuel, charity, recurring bills | Standard retail with no qualifying program |
Note what is absent from that list: how good a negotiator you are. Nothing in the interchange table responds to negotiation, which is precisely why so much processor marketing avoids mentioning it.
Interchange downgrade fees — the charge nobody explains
A downgrade is what happens when a transaction fails to qualify for the interchange category it should have reached, and settles in a more expensive one instead. On a tiered pricing plan it may appear as a “non-qualified” surcharge; on interchange-plus it simply shows as a higher interchange line. Either way you paid more, and usually for an avoidable reason.
- A card-not-present transaction submitted without complete address verification data.
- A commercial or corporate card processed without Level 2 or Level 3 data — often the single most expensive habit in B2B.
- A batch left unsettled past the network’s window, typically overnight.
- A transaction keyed in manually when the card could have been tapped or inserted.
- An authorisation amount that differs materially from the amount finally captured.
Downgrades are worth hunting for precisely because they are a process problem rather than a pricing one. They can usually be fixed without renegotiating anything or changing provider at all.
Interchange optimization in Canada — what it means and what it does not
“Interchange optimization” sounds like a discount being obtained on your behalf. It is not, and any provider implying otherwise is misdescribing it. What it actually means is making sure each transaction qualifies for the cheapest category it is genuinely entitled to.
- Capturing and transmitting the data fields the cheaper categories require, rather than leaving them blank.
- Passing Level 2 data (tax amount, customer code) and Level 3 data (line items) on commercial cards.
- Settling batches inside the network window, every day.
- Routing debit correctly, so Interac volume is not processed as something more expensive.
- Reviewing which interchange programs your business category actually qualifies for — several exist that merchants are simply never told about.
Done honestly, this is real money on a large B2B or e-commerce statement. What it can never do is take a transaction below the rate the networks set for it.
Where to find the current Canadian interchange rates
We deliberately do not reproduce the rate tables on this page. Visa and Mastercard revise them periodically, and a stale table republished by a third party is worse than no table at all — it is quotable, and it is wrong. Both networks publish their current Canadian rates themselves:
- Visa Canada interchange rates — the current tables are under “Tools and Downloads”.
- Mastercard Canada interchange rates & fees — current rates, upcoming changes and network assessment fees.
- Visa and Mastercard have both given voluntary commitments to the federal government to lower interchange for smaller Canadian businesses; whether your business qualifies is worth checking directly.
What matters more than the table is which lines of it your own transactions actually hit. That is on your statement, and it is the number worth knowing.
Questions
What are interchange fees in Canada?
Interchange is the wholesale fee paid to the bank that issued your customer's card on every transaction. It is set by Visa and Mastercard, not by your payment processor, and it is identical for every processor in Canada. Your processor pays it on your behalf and passes it on to you, adding their own markup on top.
Can a processor give me a lower interchange rate?
No. Interchange is set by the card networks and is the same for every acquirer and processor in Canada. A provider can lower the markup they add on top of interchange, and can help you avoid downgrades so your transactions qualify for cheaper categories — but nobody can sell you interchange below the network's published rate.
What is an interchange downgrade fee?
A downgrade happens when a transaction fails to qualify for the interchange category it should have reached and settles into a more expensive one. Common causes are missing address verification data on online transactions, commercial cards processed without Level 2 or Level 3 data, and batches settled outside the network window. On tiered pricing it appears as a non-qualified surcharge; on interchange-plus it simply raises the interchange line.
What is interchange optimization?
Making sure each transaction qualifies for the cheapest interchange category it is genuinely entitled to — by sending complete data, passing Level 2 and Level 3 data on commercial cards, settling batches on time, and routing debit correctly. It is a process improvement rather than a discount, and it cannot take a transaction below the rate the networks set.
Are Canadian interchange rates regulated?
Not with statutory caps, as in the European Union. Visa and Mastercard have, however, made voluntary commitments to the federal government to reduce interchange for smaller Canadian businesses. Separately, the Code of Conduct for the Credit and Debit Card Industry in Canada governs how fees and fee changes must be disclosed to merchants.
Why did my interchange go up when my pricing did not change?
Because interchange depends on which cards your customers used, not on your agreement. A month with more premium rewards cards, more commercial cards, more online or keyed-in transactions, or a lower average ticket will raise your interchange total even though your processor's markup never moved.
