In 2010, the Chiefs sold their Junior A CSHL franchise to the local Michigan Mountain Cats organization (who were also fielding a Junior B team in the GLJHL).[2] The Mountain Cats would actually end up using the Canfield Ice Arena for the first half of the 2010–11 season until finally moving into a home rink in nearby Farmington Hills, Michigan. Since 2014, the Chiefs' and Mountain Cats' Tier III junior franchise has operated as the Southern Tier Xpress out of Northwest Arena in Jamestown, New York.
The Chiefs continued with their Junior B GJLHL team, which was promoted by USA Hockey to Junior A in 2011, until summer 2012.
Inline hockey
In 2012, the GLJHL left USA Hockey-sanctioning for the Amateur Athletic Union. This caused eight of the former Jr. B-level ice hockey teams to leave the GLJHL for the Minnesota Junior Hockey League, not including the Chiefs. With the lack of teams, the GLJHL decided to take a new direction for the 2012–13 season and switched to junior roller in-line hockey. At this time, the Chiefs also dropped its junior ice hockey team and focused on the roller hockey team. The GLJHL changed its name to Great Lakes Inline Hockey League in 2014. As of 2015, the GLIHL appears to have ceased operations. The Chiefs played the 2014–15 season in the American Inline Hockey League but have since been quiet.[3]
