Mike de Jong served as the minister responsible for gaming between 2013 to 2017, a time when suspicious transactions in B.C. peaked.
Cullen found that between 2013 and 2015, de Jong "took no meaningful action in response."
"It does not appear that Mr. de Jong received information that would have led him to identify a need for action," Cullen wrote.
In September 2015, de Jong received alarming information about the state of the industry, including that in 2014, BCLC reported 1,631 suspicious transactions with a total value of more than $195.3 million — an average of nearly 4.5 transactions and more than $500,000 per day.
De Jong responded by creating the Joint Illegal Gaming Investigation Team and issuing a letter with directions to BCLC.
Cullen wrote that de Jong accomplished these measures with "remarkable speed" but that the letter to BCLC did not go far enough, because it did not require that BCLC immediately cease accepting highly suspicious cash.
Cullen also found that prior to 2015, de Jong could have independently sought more information about the state of the industry he was responsible for.
"That it was under Mr. de Jong's watch that the tide of suspicious transactions finally turned and the suspicious cash entering the province's casinos began to decline is a testament to the significance of his efforts," wrote Cullen.
"The scale of the crisis gripping the province's casinos at this time required much more decisive action. While positive, the steps taken by Mr. de Jong were simply not commensurate with the urgency of the problem facing the industry at that time."
