British Columbia’s beleaguered gambling regulator has implemented new anti-money laundering (AML) rules to cut down on dodgy high-roller habits at its land-based casinos.

On Wednesday, the British Columbia Lottery Corporation (BCLC) announced new measures to stem the seemingly endless parade of Asian VIP gamblers walking into provincial casinos with duffel bags full of $20 bills. The regulator is likely also hoping to stem the tsunami of bad press generated by BCLC’s apparent disinterest in performing its regulatory functions.

As of Wednesday, BC casinos will require a source of funds receipt from any gambler looking to buy-in for C$10k (US$8k) or more in one or more transactions within a 24-hour period. The receipt must be dated the same day as the buy-in, and include full account details. BCLC’s AML unit will review these receipts on a daily basis.

BCLC farms out day-to-day management of its gambling operations to Service Providers, who will be required to certify each of these receipts. Failure to provide a receipt or providing “clearly suspicious” information will require Service Providers to reject the buy-in, document the refusal and report the matter to BCLC, which will launch an investigation.
