Tanner is the long-time lead for
Peter de Cruz. The team played in two
World Junior Curling Championships, winning gold at the
2010 World Junior Curling Championships (defeating Scotland's
Ally Fraser in the final) and a silver at the
2011 World Junior Curling Championships (losing to Sweden's
Oskar Eriksson in the final). 2011 was the final year of junior eligibility for de Cruz. Even though Tanner could have played another two years of juniors, he stuck with de Cruz to play in men's events. On the
World Curling Tour, the team has won two events, the 2011
Curling Masters Champéry and the
2012 Challenge Casino de Charlevoix. During the 2012-13 curling season, the team played in three
Grand Slam events, the
2012 ROGERS Masters of Curling (lost in a tie-breaker), the
2012 Canadian Open of Curling (1-4) and the
National (1-4). The next season they played in one Slam, the
2013 Canadian Open of Curling (3-3). In 2014, the de Cruz rink won their first Swiss championship, by defeating the Swiss Olympic team of
Sven Michel in the final. Tanner won a bronze medal at the
2018 Winter Olympics as a part of team de Cruz. ==Personal life==
