After playing minor hockey for his hometown team in Edmonton of the Alberta Midget Hockey League, Bouwmeester joined the Medicine Hat Tigers of the Western Hockey League for 8 games in 1998–99. After recording 61 points in 61 games in his final season with Medicine Hat, he was named to the WHL East First All-Star Team.
