Officer and the Jones team attempted but failed to repeat as the Canadian Olympic team after losing in the semifinal of the 2017 Canadian Olympic Curling Trials. Officer joined Reid Carruthers in the 2018 Canadian Mixed Doubles Curling Olympic Trials, where they advanced to the playoffs but were eliminated. The Jones team won the 2018 Scotties Tournament of Hearts, Officer's record-tying sixth title, with Shannon Birchard replacing Lawes, who, with John Morris, represented Canada at the 2018 Winter Olympic Games in mixed doubles curling. At the 2018 World Women's Curling Championship, Officer, along with Jones, Lawes, McEwen, and Birchard as their alternate, went undefeated to win the title in Officer's last world championship, as she had announced that she would be stepping away from competitive curling.
