"In December, the province imposed new rules on casinos requiring them to complete source-of-funds declarations for deposits of C$10,000 or more in cash. They were also prohibited from accepting cash from customers involved in two consecutive cash transactions until it was determined the source wasn’t suspicious or illegal.Those appear to be having a dramatic effect.
On average, roughly $5 million a month in suspicious cash was being flagged at B.C. casinos. “The money was walking in the front door,” Eby said. “People with shopping bags full of $20 bills would walk it up to the cage.”
In February, following the new measures, suspicous cash transactions dropped to $200,000, Eby said."
