Following her return from South Korea, Lawes joined the Jones team and took her spot at third back from Birchard. The team's victory in Penticton meant they won the right to wear the maple leaf at the 2018 Ford World Women's Curling Championship taking place in North Bay, Ontario. The team played very well and went through the round-robin undefeated. They would eventually beat Jamie Sinclair and her American team in the semi-final earning the right to face the Olympic champion, Anna Hasselborg of Sweden in the final. Lawes and the Jones team would have to take Hasselborg to an extra end, but ultimately won the game without having to throw their last rock. The victory was Lawes' first World Championship victory and would be the last for long-time second Jill Officer, as she announced she was stepping back from the game. Jones, with tears in her eyes, said of the final game with Officer that "I'm just so thrilled to be able to stand on top of the podium with these girls one more time." It had earlier been announced that Jocelyn Peterman would be joining the team the following season, coming over from the Chelsea Carey team to replace Officer.
