Professional Ethics: A 12.5 Million Lotto Fraud

This course examines a seven-year lottery fraud scheme in which a Canadian convenience store owner stole a $12.5 million winning ticket from a customer, exposing critical weaknesses in organizational internal controls and fraud prevention systems.

Through analysis of the Chung family's theft and the Ontario Lottery and Gaming Corporation's delayed response, participants will learn to identify the three elements of the fraud triangle—incentive, opportunity, and rationalization—and understand how inadequate segregation of duties, lack of customer-facing verification systems, and insufficient insider monitoring create vulnerabilities for occupational fraud.

The case demonstrates how system failures enabled the fraud to continue undetected for seven years despite early warning signs, and highlights the internal control improvements ultimately implemented, including mandatory ticket signing, customer-facing screens, and stricter insider win policies that CPAs can apply to protect organizational assets and detect fraud indicators in their own professional environments.
