Why do Ontario online casinos usually require me to withdraw using the same method I deposited with?

Routing your withdrawal back through your deposit method isn't arbitrary — it's a direct consequence of anti-money laundering law, and understanding why makes the whole thing less frustrating.

The AML logic behind "return to source"

Ontario's regulated online casinos are reporting entities under federal anti-money laundering legislation, which means they carry real legal obligations to FINTRAC — Canada's financial intelligence unit. Their compliance programs must identify and assess money laundering risks, apply controls to mitigate them, and detect and report suspicious transactions. One of the most effective controls for doing that is keeping the money trail clean: if funds arrive via a specific payment method tied to a verified account holder, returning winnings to that same source confirms the money is going back to the person it came from — not being redirected to a third party.

FINTRAC's own guidance flags the opposite scenario as a red flag. A client requesting the transfer of winnings to the bank account of another party is treated as a money laundering indicator. Allowing arbitrary withdrawal destinations would create exactly that vulnerability, so operators close it off by default.

Minimal gambling activity before withdrawal is also a recognized money laundering method used by criminals at both online and brick-and-mortar casinos — essentially using a gambling account as a pass-through to "clean" funds. Tying withdrawals to the original deposit method makes this harder to execute cleanly.

What Ontario's regulator actually requires

The AGCO's standards for the iGaming market reinforce this at the operator level. Before a withdrawal is permitted, operators must verify that the withdrawal is being transferred to an account of which the player is a legal holder. That requirement — verifying legal ownership of the receiving account — is much easier to satisfy when the destination is the same verified payment method used to fund the account in the first place.

All player account transactions must be uniquely identifiable and traceable to a unique individual player account, and the method and source of funds used for transactions is part of what operators are required to record. Consistency between deposit and withdrawal method supports that traceability directly.

Players must be provided with unambiguous information about all player account fees prior to making a withdrawal or deposit, and must be informed clearly and specifically of all rules and restrictions regarding deposits and withdrawals. So if a particular site's policy is more restrictive — or more flexible — than another's, the operator is required to spell that out. Check the cashier section or the terms before you deposit if the withdrawal method matters to you.

The practical side for Toronto players

In practice, this policy is most noticeable when you deposit via a method that doesn't support withdrawals — some prepaid cards and certain e-wallets fall into this category. In those cases, operators typically route your funds back to your bank account instead, which is a legitimate fallback. What they won't do is send money to an account or card that isn't yours, or to a payment method you haven't already verified through the deposit process.

If you're ever unsure whether a site you're using is legitimately registered in Ontario's regulated market, look for the iGaming Ontario and BetGuard logos displayed on the site — those are markers of a properly registered operator. The full live list of registered operators is maintained at the iGaming Ontario registry. The AGCO's Registrar's Standards for Internet Gaming are designed to ensure that player protections, game integrity, responsible gambling safeguards, and anti-money laundering protections are all in place. The same-method withdrawal rule is one of those protections working as intended — it keeps your money yours, and keeps the audit trail clear for everyone.
