Ontario Casino Source of Funds / Source of Wealth Check Guide（2026）

Under AGCO and iGaming Ontario regulations, licensed casinos must verify not just your identity, but also the legitimacy of the money you wager. This is known as a Source of Funds (SoF) or Source of Wealth (SoW) check. These checks are triggered when your activity exceeds certain risk thresholds or appears inconsistent with your financial profile.

This guide explains why Ontario casinos request SoF/SoW evidence, what documents are accepted, how long reviews take, and how to avoid unnecessary delays.

What Is a Source of Funds (SoF) Check?

The SoF check confirms that the specific money used for deposits or withdrawals comes from a legitimate, traceable source. This focuses on the transactional level — where the money for a particular deposit originated.

• Bank account used for deposits
• Paystub covering the period of the deposits
• e-Transfer/iDebit/INSTADEBIT bank statements
• Proof of sale (car, crypto, stocks)

SoF is about the immediate source feeding the gambling activity.

What Is a Source of Wealth (SoW) Check?

SoW verification determines whether your overall financial situation reasonably supports your gambling behaviour. This focuses on your long-term, accumulated wealth — not individual transactions.

Examples of SoW include:

• Annual income from employment or business
• Investment portfolio or property ownership
• Inheritance, settlement, or trust income
• Tax returns or Notice of Assessment (NOA)

SoW is a higher-level review often used for high spenders, VIP players or accounts showing unusually high velocity.

Why Ontario Casinos Perform SoF/SoW Checks

Casinos are legally required to perform SoF/SoW checks under:

• AGCO Standards for Internet Gaming
• iGaming Ontario (iGO) Anti-Money Laundering Framework
• FINTRAC guidelines on large or suspicious transactions

Typical triggers include:

• High deposit velocity (rapid deposits over a short period)
• Large deposits inconsistent with profile
• Use of multiple payment methods
• High withdrawal requests shortly after deposit
• Unusual patterns (e.g., looping funds between casino & bank)
• Frequent failed deposits from multiple banks/cards

Most SoF checks are automated through the casino’s risk engine and escalate only when red flags persist.

Accepted Documents for Source of Funds (SoF)

Casinos may request any combination of the following:

• Full bank statement (showing name, address, transactions)
• Deposit screenshots showing the transfer to the casino
• Paystubs from the past 3 months
• E-transfer confirmation (Interac, iDebit, INSTADEBIT)
• Proof of loan or line of credit (not recommended for gambling)
• Proof of asset sale (vehicle, crypto, stocks)

Documents must be:

• Clear and unedited
• Matching your legal name & address
• Recent (within 90 days)

Accepted Documents for Source of Wealth (SoW)

• Tax returns / NOA (most trusted)
• Annual income statement
• Business ownership documents
• Investment portfolios or brokerage statements
• Property ownership records
• Inheritance documentation

SoW is required when your gambling volume exceeds what your income reasonably supports.

How Long Do SoF/SoW Checks Take?

Typical review windows at Ontario casinos:

• SoF Review: 24–72 hours
• SoW Review: 3–7 business days
• Complex AML escalations: 7–14+ days

Delays occur when documents are incomplete, mismatched, or unclear.

Common Reasons Your SoF/SoW Is Rejected

• Name on bank statement does not match the casino account
• Redacted or blurred documents
• Third-party payment activity (very high AML risk)
• Deposits made from multiple unrelated sources
• Income too low compared to gambling activity
• Large crypto or cash deposits without documentation

How to Pass SoF/SoW Quickly

• Use a single primary bank account
• Avoid switching payment methods frequently
• Keep all documents in high resolution
• Ensure your bank address matches your casino profile
• Provide complete statements, not cropped screenshots
• Upload PDF bank statements when possible (preferred by AML teams)

What Happens If You Fail the SoF/SoW Check?

If the casino cannot verify your funds, they may:

• Freeze the account
• Cancel pending withdrawals
• Return deposits to the original source
• Report the case to FINTRAC (if thresholds met)
• Permanently close the account

This is why responding fast and providing complete documents is critical.
