Shattler has competed internationally with the Iroquois Nationals, the national box lacrosse team of the Iroquois Confederacy. By virtue of his First Nations status, it would have been possible for him to play for Canada, the United States, or the Nationals. About choosing to play with the Nationals, Shattler said, “It’s always been my culture... Probably my grandma would kill me if I did play for Team Canada.“ With the Nationals, Shattler won silver medals at the World Indoor Lacrosse Championships in 2011 and 2015. He was named to the 2015 WLIC All World Team at the transition position.
In February 2019, Shattler established the Shattler Lacrosse Academy, a privately owned elite lacrosse academy sanctioned by the Saskatchewan Lacrosse Association. In addition to organizing clinics and offering private training through his namesake academy, Shattler serves as Director of Player Development and Coaching for the Fighting Sioux lacrosse program of Standing Buffalo Dakota Nation, a role he has held since 2019. His is also involved in an effort to establish a nations cup between eight reserves in the Sanding Buffalo Dakota Nation and File Hills Qu’Appelle Tribal CouncilTreaty 4 area. He also dedicates time to clinics and programs that aim to expand opportunities for girls in lacrosse, including working once a month with Queens Lacrosse of Queen City Minor Box Lacrosse league, the first all-girls lacrosse team in Regina, Saskatchewan.
Personal life
Shattler’s mother, Donna Lewis Babstock, is Ojibwa from Wiikwemkoong Unceded Territory. His father is Inuit, originally from northern Quebec. He is the second eldest of six siblings, having one older sister, three younger sisters, and a younger brother. Shattler played junior ice hockey with the Brampton Capitals of the Ontario Junior Hockey League in the 2003–04 and 2004–05 seasons and was offered a scholarship to play NCAA Division I hockey at Cornell. After a long talk with his sister, Cindy Shattler, he decided to focus exclusively on sport rather than pursue collegiate athletics and felt that lacrosse offered him better opportunities. He has called Cindy the most positive influence on him as a lacrosse player. Beginning early in his playing career, his maternal grandmother, Gene Waseigijig, encouraged him to play for “a native team” and he has cited her as one of the reasons he chose to compete internationally with the Iroquois Nationals rather than with the Canadian national team. One of his younger sisters, Kelly Babstock, plays ice hockey with the Toronto Six of the NWHL. Shattler resides in Regina, Saskatchewan, with his wife, Lindsay, and their children, Ada and Jace. He is a glazier by trade.
