2010-11: Josh Ho-Sang skated for the Toronto Marlies bantam and midget teams and joined the midget AAA team for its championship run at the 2011 OHL Cup. In seven games at the tournament he scored 4 goals with 5 assists and had 2 penalty minutes.
2011-12: Ho-Sang was dominant in Ontario midget hockey skating alongside 1997-born forward Connor McDavid for the Toronto Marlies. In 30 regular season games he scored 31 goals with 48 assists and had 24 penalty minutes. The Marlies reached the OHL Cup championship game against the Don Mills Flyers and in five games Ho-Sang scored 2 goals with 4 assists and 19 penalty minutes. Ho-Sang was the fifth player taken in the 2012 OHL Priority Draft when he was selected in the first round by Windsor.
2012-13: Ho-Sang skated in 63 OHL games for Windsor as a 16-year-old and played for Canada Ontario in the 2013 U17 World Hockey Challenge. He scored 14 goals with 30 assists and was -23 with 22 penalty minutes. One of the OHL’s youngest teams, the Spitfires missed the playoffs; finishing last in the West Division. Ho-Sang scored 3 goals with 2 assists for Canada Ontario in five games at the WHC.
2013-14: Ho-Sang returned to Windsor and was part of a resurgence for the Spitfires; leading the team in scoring. He scored 32 goals, tying Brady Vail for the team lead, and had 53 assists in 67 regular season games; finishing plus-26 with 44 penalty minutes. Windsor finished second in the West Division and lost to London in a first round playoff series. Ho-Sang scored 1 goal, a power play goal, and was minus-10 with 2 assists and 10 penalty minutes in the four-game series. He was selected to compete for Team Orr in the 2014 CHL/NHL Top Prospects Game. Ranked 22nd amongst North American skaters in the Central Scouting final rankings he was selected by the Islanders in the first round (28th overall) in the 2014 NHL Draft.
Ho-sang is among the most skilled prospects in the Islanders system with his potential, flashy hands and the ability to put up points. On the other side of things, some have criticized him at times for his perceived selfish play and attitude problems. His abilities with the puck are rare and Ho-Sang can be a game breaker.
Ho-Sang attended his first NHL training camp with the Islanders before returning to Windsor for his third OHL season in 2014-15. Suspended for the first six games of the season as a result of a hit in last year's playoffs, he skated in 11 games with the Spitfires and was the team's leading scorer before being traded to Niagara in exchange for Hayden McCool and three draft picks. In the short-term the trade appears to move Ho-Sang from one struggling team to another one. The change of scenery could offer a fresh start. Not invited to Canada’s World Junior summer camp, Ho-Sang recorded a goal and two assists in the OHL all-stars 5-1 win over Russia in the Subway Series and could be playing his way into consideration. In terms of his NHL potential, his skill set would definitely fit in with an Islanders organization that is loaded with skilled young players. The presence of strong personalities like Kyle Okposo, John Tavares and Ryan Strome should provide a positive influence.
