Courtney Smith at the
2010 The Dominion Curling Club Championship. The team qualified for the playoffs through a tiebreaker before losing to Alberta in the semifinals. They rebounded in the bronze medal game by defeating Manitoba for third place. Barker played for several different skips throughout her career including
Sarah Murphy,
Kelly Backman and
Nancy McConnery, with whom she won the 2016 Lakeshore Curling Club Cashspiel. For the
2018–19 season, she joined the
Kristen MacDiarmid with third Kelly Backman and second
Karlee Jones. The team made the playoffs in three of their four tour events this season, reaching the semifinals of the
Dave Jones Mayflower Cashspiel and the

Lady Monctonian Invitational Spiel. At the
2019 Nova Scotia Scotties Tournament of Hearts, the team finished in a four-way tie for second place with a 4–3 record. They were able to beat

Julie McEvoy took over skipping duties for Kristen MacDiarmid for the
2019–20 season. In their four tour events, they reached the playoffs twice. The team was not able to find success at the
2020 Nova Scotia Scotties Tournament of Hearts, finishing winless through their seven games. Team McEvoy disbanded after just one season together. For the
2020–21 season, Everist and Barker teamed up with
Christina Black and
Jenn Baxter. In their first event together, the team won the 2020
The Curling Store Cashspiel. The 2021 Nova Scotia Scotties was cancelled due to the
COVID-19 pandemic in Nova Scotia, so the Nova Scotia Curling Association appointed Team
Jill Brothers to represent the province at the
2021 Scotties Tournament of Hearts. Team Black won their first event of the
2021–22 season, The Curling Store Cashspiel, going undefeated to claim the title. They also reached the final of the
Atlantic Superstore Monctonian Challenge, losing to the
Andrea Crawford rink. In November, the team once again went undefeated to win the
Tim Hortons Spitfire Arms Cash Spiel, defeating
Jennifer Crouse in the final. At the
2022 Nova Scotia Scotties Tournament of Hearts, Team Black won all three qualifying events, winning the provincial title and securing their spot at the
2022 Scotties Tournament of Hearts. At the Hearts, Team Black finished the round robin with a 5–3 record, which was enough to qualify for the championship round. Along the way, they scored victories over higher seeded teams such as Alberta's
Laura Walker and Manitoba's
Mackenzie Zacharias. In their championship round match against Northern Ontario's
Krista McCarville, Team Black got down 9–1 before coming back to make the game 9–8, eventually losing 11–8. This eliminated them from the championship. The Black rink began the
2022–23 season at the inaugural
PointsBet Invitational where they lost to
Kelsey Rocque in the opening round. They bounced back immediately in their next event, however, winning the New Scotland Clothing Women's Cashspiel in a 6–4 final over
Tanya Hilliard. At the
2022 Tour Challenge Tier 2
Grand Slam of Curling event, the team went undefeated until the semifinals where they were defeated by
Jessie Hunkin. Through November and December, they qualified for three straight finals. After losing to the
Kaitlyn Lawes rink, skipped by
Selena Njegovan, in the final of the
2022 Stu Sells 1824 Halifax Classic, they once again defeated Jennifer Crouse at the Tim Hortons Spitfire Arms Cash Spiel and then beat
Marlee Powers in the final of the Bogside Cup. At the
2023 Nova Scotia Scotties Tournament of Hearts, Team Black won both the A and B events to earn two of the three spots in the playoffs. They then beat the Hilliard rink 9–4 in the semifinals to claim their second consecutive Nova Scotia Scotties title. This qualified the team for the
2023 Scotties Tournament of Hearts in
Kamloops,
British Columbia where they again went 5–3 through the round robin. This qualified them for a tiebreaker where they stole in an extra end to upset the Lawes Wild Card rink. In the championship round, they again stole in an extra to beat Ontario's
Rachel Homan rink before losing to Northern Ontario's McCarville in the seeding game. They then fell 9–4 to Team Canada's
Kerri Einarson in the 3 vs. 4 game, settling for fourth. The
2023–24 season began well for Team Black as they reached the final of the Summer Series, losing 5–4 to
Danielle Inglis. In their third event, they reached another final where they narrowly lost to
Jessica Daigle. With their success from the previous season, the team qualified as the sixth seeds for the
2023 PointsBet Invitational. After defeating
Nancy Martin in the opening round, they upset
Jennifer Jones in the quarterfinals before dropping the semifinal to Rachel Homan. In their next two events, the team reached the quarterfinals of both the
2023 Tour Challenge Tier 2 and the Stu Sells 1824 Halifax Classic, losing out to
Madeleine Dupont and
Stefania Constantini respectively. In November 2023, the team ranked sixteenth in the world, qualifying them for the
2023 National Tier 1 Slam. They finished with a 1–3 record, earning a victory over Korea's
Ha Seung-youn. At the
2024 Nova Scotia Scotties Tournament of Hearts, the team easily qualified for the playoffs through the A event. They then lost to
Heather Smith in the 1 vs. 2 game but defeated
Mackenzie Mitchell in the semifinal to reach the final. There, they could not defend their provincial title for a third time, dropping the final 6–4 to Team Smith. After the season, Barker stepped back from competitive women's play. ==Personal life==
