The Massachusetts Gaming Commission will hold a suitability hearing for Crossroads LLC, the corporate entity behind the Foxwoods Massachusetts casino proposal in Milford, Wednesday at 9:30 a.m. at the Boston Convention and Exhibition Center. The hearing is the next step in determining whether the state board will accept the Foxwoods application for the one resort casino license to be issued in Greater Boston. Foxwoods is proposing to build a $1 billion complex next to Interstate 495 and Route 16, near Milford’s border with Holliston. The commission has found two applicants unsuitable for gaming licenses: Ourway Realty, which had applied for a slots license at the Plainridge Racecourse in Plainville, and Caesars Entertainment, which was part of the group seeking to build a resort casino at Suffolk Downs. Foxwoods spokesman Stephen Oakes said the Connecticut company is certain that it will meet the commission’s standards. “We’re 100 percent confident in the results of our background check and believe our best practices will stand up at the suitability hearing,” he wrote in an e-mail to the Globe. Casino opponents are hopeful Oakes is wrong. Geri Edins of Casino-Free Milford said in an e-mail that her group is pleased that the hearing is taking place before the town’s Nov. 19 binding referendum on the proposal, “as this information is critical to all Milford voters.” The special election will ask voters whether they approve of the host community agreement negotiated by the Board of Selectmen and Foxwoods.
