The 2015 World Indoor Lacrosse Championship was hosted by the Onondaga Nation, south of Syracuse, New York.[10] Canada defeated the host Iroquois Nationals 12–8 in the gold medal game, the same finals match-up featured in all four indoor championships.[11]

Most games were held on the Onondaga Reservation at the Onondaga Nation Arena and the newly-built $6.5 million Onondaga Nation Fieldhouse, although the Iroquois' games versus Canada and the United States were held at War Memorial Arena in Syracuse and the gold and bronze medal games were held at the Carrier Dome.[12][13]

The opening ceremonies in the sold-out War Memorial Arena featured a light show about the Haudenosaunee creation story and traditional dancing.[14] The documentary Spirit Game: Pride of a Nation explains the meaning of lacrosse to the Iroquois people and covers the Iroquois Nationals in the 2015 WILC, featuring brothers Lyle and Miles Thompson.[15]

In 2015, the Six Nations held the inaugural World Lacrosse Challenge, an under–19 box lacrosse tournament featuring international club and national teams. The Iroquois fielded three teams, with the Iroquois West team winning bronze.[18]

The tournament changed its name to the IIJL World Junior Lacrosse Championship in 2016 and added an under–17 division. The Iroquois had three under–19 teams; West, East, and Grand River and an under–17 team.[19] The Iroquois West team took gold, with the Iroquois Grand River winning bronze. The under–17 Iroquois team defeated Canada's under–17 squad to win gold.[20]

After a one year hiatus, the 2018 IIJL World Junior Lacrosse Championship returned was a change in format again, this time a full round robin tournament featuring national teams, the United States, Canada, and Iroquois. With half its roster missing due to travel delays, the Iroquois lost to Canada in the opening game of the tournament. After defeating the United States, the Iroquois reached the championship game, but lost in the rematch with Canada.
