The Mohegan Sun Casino, based in Connecticut, is suing the owner of the Ottawa Senators over an alleged unpaid gambling debt. In the lawsuit, the casino claims Eugene Melnyk attempted to pay the casino five bank drafts totalling $900,000 between March 17, 2017 and March 19, 2017 that were dishonoured by the bank. Four of the drafts were for $200,000 apiece and the last was for $100,000.

Melyck was listed 92nd on a 2018 list of Canada's 100 richest people. His net worth is estimated at $1.2 billion. He made his fortune in the pharmaceutical industry, acquiring the NHL's Ottawa franchise in 2003.

An attorney for Mohegan Sun attests that he spoke with Melnyk's corporate lawyer on Aug. 9 and believes Melnyk is aware of the suit. The casino will not comment on the matter any further and Melnyk has not issued any statements regarding the suit.
