In 2018 Morris joined up with Kaitlyn Lawes to win the 2018 Canadian Mixed Doubles Curling Olympic Trials to return to the Winter Olympics, this time in Pyeongchang, South Korea, where the mixed doubles made its debut. Morris had been playing with Rachel Homan in pre-trials events, but had to find a new partner after Homan became ineligible when her women's team won the right to represent Canada in the Olympic women's event. Morris and Lawes won the gold, defeating Switzerland in the final.
