UK-listed online gambling operator GVC Holdings is facing a potential class action lawsuit in Canada stemming from the collapse of an alleged joint venture involving its Sportingbet brand.

Ontario-based law firm Findlay McCarthy PC recently launched a website seeking submissions from Canadian sports bettors who registered with Sportingbet between 2005 and 2015.

The firm says it is considering a class action “seeking reimbursement on behalf of betters [sic] of all bets placed by Canadian residents” with Sportingbet during the period in question. The law firm said it also intends to seek “substantial punitive damages” against GVC should the allegations against the company prove correct.

The action is related to a suit filed last August by Doug Honeger, a Montreal-based sports and entertainment consultant, who claims his 37 Entertainment Inc (37E) entered into a joint venture with GVC to launch two Sportingbet-branded websites serving Canadian sports bettors.
