King City was the home of the Metro Junior B's King City Dukes from 1984 until 1986 when they were sold off to interest in Richmond Hill, Ontario. The Dukes were founded as the Weston Dukes, but now exist as the Mississauga Chargers.
The King Wild's first game was the first game in the GMHL's history. The game took place on September 8, 2006 against the Richmond Hill Rams in Richmond Hill, Ontario. The Wild lost 6-0 to the Rams despite outshooting them. The Wild's first victory was a 5-1 decision over the Toronto Canada Moose on September 9, 2006. The team's first home game was against the Nipissing Alouettes on September 10, 2006. The Wild were victorious, winning by a close 5-3 score.
The 2006-07 finalists started the 2007-08 season off rather slow. After playing poorly for most of the season, the Wild surged in the last quarter, and with a long winning streak drew a .500 record by the final regular season game. In the bye round of the playoffs, all byes had been picked and the final two teams remaining were the Wild and the Douro Dukes who would play in the first round practically by default. Although the Dukes played inspired hockey, the Wild swept the series 4-0. The Wild put on a tough show for the Temiscaming Royals in the league quarter-finals, but were still defeated by the second seeded team in six games.
In March 2008, the Wild and the Richmond Hill Rams challenged the Mexico national ice hockey team to a set of four exhibition games. The first of two games for the Wild happened on the 22nd, as the Wild defeated the Mexican Senior team 7-6 in overtime. On the 25th, the Wild played them again and beat them again 7-6, this time in regulation.
In the summer of 2011, the Vaughan Wild moved to Lefroy, Ontario and became the Lefroy Wave.
