An Ontario casino says customer information has been stolen after an alleged cyberattack.

The Casino Rama Resort in Rama, Ont., says its customers, vendors and current and former staff should keep an eye on their bank accounts, credit cards and other financial information.

The resort says it became aware of the situation on Nov. 4.

It says customers' credit inquiries and collection and debt information were stolen, along with employees' information, including payroll data, social insurance numbers and dates of birth.

It says vendor information was also stolen.

The Ontario Lottery and Gaming Corporation says the attack was site-specific, so customers who visited other casinos don't need to worry.

Casino Rama says there's no indication that the alleged hacker still has access to the system, but it warns some or all of the stolen information could be published.

Police are investigating.
