The league features six franchises, which are located through Central-eastern Ontario in Amherstview, Campbellford, Frontenac (near Godfrey), Napanee, Port Hope, and Picton. The Port Hope Panthers is the new name of the transferred Colborne Cobras franchise.
The teams play a 40-game regular season, with four home and away dates against each of the other Empire B teams, and the top four teams make the playoffs — two rounds of best-of-seven play. The Empire playoff champions will advance to the OHA quarterfinals against the Central champions and compete for an All-Ontario Championship and the Clarence Schmalz Cup. In its 20-year history, only one Empire B team, the 1993 Napanee Raiders, has won the Schmalz Cup. The Raiders also advanced to the finals in 1996 and recently returned to the semifinals in 2008.
The Empire league has had a number of winners of the OHA Junior C player of the year award. Most recently, Napanee's Pete Sergeant took the honours in 2008-2009. Among the previous winners are Jason Sutton (Napanee), Adam Walsh (Picton), Joe Curry (Campbellford), and Ryan Zufelt (Amherstview). It is a remarkable accomplishment.
Though just entering its 21st season, the league has had a few graduates make it to the NHL. In 2006, Carolina's Justin Williams became the league's first graduate to hoist the Stanley Cup. He played with the former Colborne/Brighton franchise. Former Amherstview Jets defencemen Jay McKee (Pittsburgh), Bryan Allen (Florida), and Kip Brennan (New York Islanders) have also skated in the pro league.
At the conclusion of the 2014-15 hockey season the Eastern Ontario Junior B Hockey League announced a re-organization which saw them delete 6 teams from the league. One of those teams, the Gananoque Islanders immediately petitioned and was accepted into the Empire B Junior C League.
