In the months leading up to the 2015 FIFA Women's World Cup, McLeod joined the Canadian national team as they took part in an extended residency in order to prepare and train. McLeod and the Canadian national team started off the year at the Four Nations Tournament. While McLeod was on the roster for the tournament, she did not play in any of the three games, allowing fellow Canadian Stephanie Labbé to gain experience. McLeod made her first appearance of the year at the Cyprus Cup in March, where she appeared in three of the four matches that Canada played, recording three shutouts. She also appeared in two other friendlies against France and England in April and May. In April 2015, McLeod was named to the 23-player Canadian roster for the FIFA Women's World Cup hosted by Canada. As Canada's veteran goalkeeper, she started in net for all five of the team's matches, recording three shutouts, and helping Canada earn a sixth-place finish. The team's one loss came in the quarter-finals against England, which halted their advancement in the tournament. Although McLeod had an impressive tournament, she was left off both the Golden Glove shortlist and the FIFA Technical Study Group All-Star Squad.
