Juniors Walker began her junior curling career as a skip. In 2008, her Scarboro Golf & Country Club rink made it to the
provincial junior championships where her team finished with a 2–5 record. In 2010, Walker was invited to join the
Rachel Homan junior rink at the second position. The team's regular second,
Alison Kreviazuk, was too old to play in juniors that season (but played with the team in
World Curling Tour events). The rink would win the provincial championship and the
2010 Canadian Junior Curling Championships, and would then make it to the final of the
2010 World Junior Curling Championships where they lost to Sweden. The following season, Walker and lead
Lynn Kreviazuk joined up with the
Clancy Grandy junior rink. With Grandy, Walker won her second straight provincial championship but finished with a 5–7 record at the
2011 Canadian Junior Curling Championships, missing the playoffs. While Walker was finding success with her junior career, she also found success representing
Wilfrid Laurier University as a university curler, where she attended school from 2008 to 2012. Walker won the
2011 CIS/CCA Curling Championships defeating
Brock University in the final. In her final year at Laurier, Walker would repeat her championship, winning in the final of the
2012 CIS/CCA Curling Championships against Brock once again. Walker graduated that year from Laurier with a BA in Psychology.
Women's Following the
2011–12 season, Walker and teammates
Sarah Wilkes and
Jen Gates moved from Ontario to curl out of
Edmonton,
Alberta where they were joined by Albertan
Rebecca Pattison. Walker played in her first WCT
Grand Slam event at the
2012 Curlers Corner Autumn Gold Curling Classic, where her team lost in the quarter-finals. At the second Grand Slam of the season, the Crocker rink repeated that success by finishing in the quarterfinals of the
2012 Manitoba Lotteries Women's Curling Classic. However at the next Slam, the
2012 Colonial Square Ladies Classic her team would miss out at the quarters, by losing in the round of 16. At the
2012 Masters Grand Slam of Curling, the rink went 0–5. The team qualified for the
2013 Alberta Scotties Tournament of Hearts, Crocker's first provincial women's championship appearance. The team began the tournament with four straight victories, but lost both of their playoff games. To wrap up the season, the Crocker rink made it to the quarter-finals of the
2013 Players' Championship. After the season, Wilkes became the team's alternate and was replaced by
Erin Carmody at third. To start the
2013–14 season, the Crocker team played in both the
2013 Curlers Corner Autumn Gold Curling Classic and the
2013 Manitoba Liquor & Lotteries Women's Classic, failing to make the playoffs in either event. Her team played in the
2013 Canadian Olympic Curling Pre-Trials, winning two games, but not qualifying for the Olympic Trials. Next, Walker played in the
2013 Winter Universiade with her Laurier University rink which included Wilkes, Gates and lead
Cheryl Kreviazuk. She would lead the team to a 4–5 record, missing the playoffs. Walker finished the season by playing third for
Val Sweeting at the
2014 Players' Championship, where they would miss the playoffs. Effective as of March 11, 2014, the team announced that
Chelsea Carey would take over as skip of the team. Walker would move to third and Gates would remain at lead. Wilkes has left the team.
Taylor McDonald was recruited to play second for the team, while Carmody left the team. The team would win two tour titles that season, the
HDF Insurance Shoot-Out and the
Boundary Ford Curling Classic. The team played in three slams that season, making the playoffs in only the
2014 Canadian Open of Curling, where they lost in the quarterfinals. At the
2015 Alberta Scotties Tournament of Hearts, the team would lose in the finals. Following the 2014–15 season, Carey formed a new team, and was replaced by
Kelsey Rocque as the team's skip. In their first season together, the Rocque rink won the
Red Deer Curling Classic and the
CCT Uiseong Masters on the tour. The team played in five slams, making it to the quarterfinals in four events. Team Rocque played in the
2016 Alberta Scotties Tournament of Hearts, but failed to make the playoffs. The team also played in the
2015 Canada Cup of Curling, but finished with a 2–4 record, missing the playoffs. The following season, the team had less success on the tour. They would play in four slams, making it to the quarterfinals in just one event, the
2016 GSOC Tour Challenge. The team played in the
2016 Canada Cup of Curling, but once again missed the playoffs with a 2–4 record. In the
2017–18 season, Team Rocque would win the
Curl Mesabi Classic and would play in three slams, making it to the quarterfinals at just the
2018 Meridian Canadian Open. The team played in the
2017 Canadian Olympic Curling Pre-Trials, losing in the playoffs. Midway through the season, Walker took over skipping duties of the team, but remained throwing third stones. The Rocque rink played with the new arrangement at the
2018 Alberta Scotties Tournament of Hearts, where they narrowly missed the playoffs. The next month it was announced that the team would be splitting up. In their final event together, with Rocque off the team, the rink would lose in a tiebreaker at the
2018 Players' Championship with Walker skipping and
Kendra Lilly brought in to play third. For the
2018–19 season, Walker skipped a new team of
Cathy Overton-Clapham,
Lori Olson-Johns and
Laine Peters. They played in four of seven Slams and were knocked out of the
2019 Alberta Scotties Tournament of Hearts 9–2 by
Jodi Marthaller. Outside of her team, Walker spared in two other Grand Slam events. She replaced
Joanne Courtney on
Team Homan at the
Players' Championship partway through the event and replaced
Allison Flaxey at skip for her team at the
2019 Champions Cup, where they had a quarterfinal finish. On March 15, 2019, it was announced that Walker was once again skipping a new team of
Kate Cameron,
Taylor McDonald and
Nadine Scotland for the
2019–20 season. They did not qualify for the playoffs in their first two events, the
2019 Cargill Curling Training Centre Icebreaker and the
Booster Juice Shoot-Out before winning the 2019
Mother Club Fall Curling Classic after posting a perfect 7–0 record. Walker won her first provincial title this season as well, defeating former teammate
Kelsey Rocque 7–4 in the
2020 Alberta Scotties Tournament of Hearts final. Representing Alberta at the
2020 Scotties Tournament of Hearts, Walker led her team to a 3–4 record, failing to qualify for the championship round. It would be the team's last event of the season as both the
Players' Championship and the
Champions Cup Grand Slam events were cancelled due to the
COVID-19 pandemic. Due to the pandemic, the 2021 Alberta Scotties were cancelled, so
Curling Alberta appointed the Walker rink to represent the province at the
2021 Scotties Tournament of Hearts. Walker's regular lead
Nadine Scotland, who was three-months pregnant, opted not to play in the tournament, which was being held in a "bubble" due to the pandemic. She was replaced by
Rachel Brown. Due to COVID restrictions, there was no one in attendance for the event, including family members, but Walker, was allowed to bring her five month-old son and her husband as a caregiver. Her son was the only baby in the "bubble". In the tournament itself, Walker led Alberta to a 9–3 round robin record, tied for third with Manitoba, skipped by
Jennifer Jones. Walker beat Jones in the tiebreaker, but lost in the semifinal against the defending champion Team Canada rink, skipped by
Kerri Einarson, settling for a bronze medal. Walker returned to the bubble in April 2021 as she was scheduled to spare for the
Rachel Homan rink for the only two Grand Slam events of the abbreviated season. Up until the day the event started,
Emma Miskew, Homan's third, was supposed to skip the team as Homan had just given birth to her second child three weeks earlier, with Walker substituting at third. However, Homan returned in time for the event, leaving the team's original lineup intact. The Homan rink won the
2021 Champions Cup and finished runner-up at the
2021 Players' Championship. Walker did not play in any games for the team. In just their second event of the
2021–22 season, Team Walker reached the final of the
2021 Alberta Curling Series: Saville Shoot-Out where they were defeated by
Kim Eun-jung. Due to the pandemic, the qualification process for the
2021 Canadian Olympic Curling Trials had to be modified to qualify enough teams for the championship. In these modifications,
Curling Canada created the
2021 Canadian Curling Trials Direct-Entry Event, an event where five teams would compete to try to earn one of three spots into the
2021 Canadian Olympic Curling Trials. Team Walker qualified for the Trials Direct-Entry Event due to their
CTRS ranking from the 2019–20 season. At the event, the team went 2–2 through the round robin, qualifying for the tiebreaker round where they faced British Columbia's
Corryn Brown. After being defeated by Brown in the first game, Team Walker won the second tiebreaker to secure their spot at the Olympic Trials. The team had one more event before the Trials, the
2021 National Grand Slam, where they lost in the quarterfinals to
Tracy Fleury. A few weeks later, they competed in the Olympic Trials, held November 20 to 28 in
Saskatoon,
Saskatchewan. At the event, the team had mixed results, ultimately finishing in sixth place with a 3–5 record. A few weeks before the Alberta provincial championship, Team Walker won the Alberta Curling Series: Avonair tour event, defeating
Casey Scheidegger in the final. They then competed in the
2022 Alberta Scotties Tournament of Hearts, where they posted a 6–1 record through the round robin. This created a three-way tie between Walker, Scheidegger and the
Kelsey Rocque rink, however, as Walker had to best draw shot challenge between the three rinks, they advanced directly to the final. There, they met the Scheidegger rink, who defeated Rocque in the semifinal. After a tight final, Walker secured the victory for her team with a draw to the eight-foot to win 6–5. This qualified the team for their second straight national championship. At the
2022 Scotties Tournament of Hearts, the team could not replicate their success from 2021, finishing the round robin with a 3–5 record and missing the playoffs. Team Walker wrapped up their season at the
2022 Players' Championship where they missed the playoffs. On March 17, 2022, the team announced that they would be disbanding at the end of the 2021–22 season. Walker then announced that she would be focusing solely on mixed doubles for the next Olympic quadrennial with partner
Kirk Muyres. Despite this, she became the full-time alternate on Team
Kaitlyn Lawes as both Lawes and Njegovan went on maternity leave during the year. She first stepped in for the team at the
2022 Stu Sells 1824 Halifax Classic where they won the event title. She also helped the team reach the quarterfinals of the
2022 Masters. At the
2023 Scotties Tournament of Hearts, she slotted into the third position for the team with Njegovan on leave. After a 5–3 record, they lost in a tiebreaker to Nova Scotia, skipped by
Christina Black. Walker also played for the team at three other Slams, the
2023 Canadian Open, the
2023 Players' Championship and the
2023 Champions Cup where they failed to reach the playoffs. Walker would join Team
Kaitlyn Lawes as their alternate for the
2025–26 curling season. Team Lawes would compete at the
2025 Canadian Olympic Curling Trials, with a chance to represent Canada at the
2026 Winter Olympics. At the Trials, Team Lawes would finish with a 4–3 record, just missing out on the playoffs due to Draw Shot Challenge (last stone draw). Lawes would continue the season at the
2026 RME Women of the Rings, the Manitoba women's curling championship, where they would go undefeated before losing to Team Peterson 9–7 in the championship final. However, due to Rachel Homan having to withdraw from the
2026 Scotties Tournament of Hearts as the Scotties schedule conflicted with the Olympics, an additional spot was instead given to Lawes as the highest CTRS ranked non-qualified team following the completion of all provincial and territorial championships. At the 2026 Scotties, Walker would replace regular second on Team Lawes,
Jocelyn Peterman, as Peterman was competing at the
2026 Winter Olympics. Team Lawes would make the most of their second chance, going undefeated with an 8–0 record in round-robin play and beating
Kerri Einarson 10–2 in the 1v2 game to qualify for the Scotties final. However, similarly to their record at the 2026 Manitoba championships where they went undefeated throughout the championship but lost in the final, Team Lawes would lose in a rematch against Einarson 4–3 in the Scotties final, finishing with a silver medal.
Mixed doubles In mixed doubles play, Walker plays with
Kirk Muyres. She previously played with husband
Geoff Walker until 2018. With Walker, at the
2016 Canadian Mixed Doubles Curling Trials, the pair would make it all the way to the finals before losing to the
Jocelyn Peterman /
Brett Gallant duo. The pair played in the
2018 Canadian Mixed Doubles Curling Olympic Trials, where they made it to the playoffs, but were eliminated after winning two playoff games. With her husband playing in the
2018 World Men's Curling Championship, Walker had to find a new doubles partner in Muyres for the
2018 Canadian Mixed Doubles Curling Championship. The pair found immediate success, winning the event, defeating
Colton Lott and Kadriana Sahaidak in the final. The pair represented Canada at the
2018 World Mixed Doubles Curling Championship, where they won a bronze medal. They also represented Canada in the first leg of the 2018
Curling World Cup in
Suzhou, China, which they would end up winning, defeating the United States (
Korey Dropkin and
Sarah Anderson) in the final. At the
2021 Canadian Mixed Doubles Curling Championship, Walker and Muyres went 6–0 through the round robin before losing in the 3 vs. 4 game to
Kerri Einarson and
Brad Gushue, placing fourth. In the next championship, the
2023 Canadian Mixed Doubles Curling Championship, the team again went undefeated in the round robin before losing in the quarterfinals to
Brittany Tran and
Aaron Sluchinski. Following the 2021-22 season, both Walker and Muyres decided to focus their careers strictly to the Mixed Doubles discipline to push for an Olympic appearance in 2026. Walker and Muyres would qualify for the
2025 Canadian Mixed Doubles Curling Olympic Trials, however would narrowly miss the playoffs, tied with
Jennifer Jones and
Brent Laing with each having 4–3 records after round robin play, but Jones/Laing winning the tie-breaker 9–3 in their head-to-head game. ==Personal life==
