In December 2015, Kennedy, along with his teammates, claimed the first berth in the 2017 Canadian Olympic Curling Trials with their Canada Cup victory in Grande Prairie, AB. The team continued their winning ways that season by winning the 2016 Tim Hortons Brier and a gold medal at the 2016 World Men's Curling Championship. Representing Team Canada as defending champions, the team lost in the final of the 2017 Tim Hortons Brier.
