The Toronto Transit Commission has fired three more employees for allegedly claiming fraudulent benefits as part of an investigation that had already seen five employees lose their jobs.

The TTC announced the firings in a news release, and as part of an ongoing process. Toronto police are also investigating.

In July 2015, police laid charges against the owner of a company called Healthy Fit after it was alleged that receipts were provided to customers at inflated prices or for services that were never provided. Allegedly the company and those making the claims to the TTC's insurer, Manulife Financial, were sharing the money.

The TTC's employee benefit plan was allegedly defrauded of more than $4 million. Three people were arrested last year in connection with the alleged benefits scam.

Criminal charges have not been laid against any TTC employees, but the commission is demanding full repayment for improper claims.
