Birchard also won the 2018 Scotties Tournament of Hearts with Jennifer Jones when she filled for Kaitlyn Lawes who was competing at the PyeongChang Olympics.
She would win a world championship as the alternate member of the Jones team that same year when they won the event in North Bay in 2018.
[4] At the 2012 Canadian Junior Curling Championships, Birchard led her team of Selena Kaatz, Kristin MacCuish and Mariah Mondor to a 10-2 round robin record, giving her rink a bye to the finals, where she lost to Alberta's Jocelyn Peterman.
At the 2013 Canadian Junior Curling Championships, she led her team of Nicole Sigvaldason, Sheyna Andries and Mondor to a 9–1 record before the playoffs.
There, she won the semifinal game against Ontario's Jamie Sinclair before losing in the final to Corryn Brown's British Columbia rink.
Her team played in the 2017 Manitoba Scotties Tournament of Hearts, again making the playoffs after winning a tiebreaker game after a 4–3 record.
Birchard and her team began the 2017–18 season by winning the 2017 Colonial Square Ladies Classic, after beating defending Olympic champion Jennifer Jones in the final.
In their matches against the Czech and Italian teams, Birchard had a chance to play in the second half, replacing Lawes and Jill Officer in each of their games well under control.
[10] For the 2018–19 season, Birchard joined a new team with Kerri Einarson, Val Sweeting, and Briane Meilleur, all former skips.
[11] They began the season by winning three straight World Curling Tour events in three weeks: the 2018 Stu Sells Oakville Tankard, the inaugural Morris SunSpiel and then the Mother Club Fall Curling Classic[12] with a fourth win at the Curlers Corner Autumn Gold Classic in October.
Their strong play during the early part of the season earned them enough points to put team Einarson in the Wild Card game at the 2019 Scotties Tournament of Hearts.
The team would rebound to have a strong finish at the end of the season, winning the 2019 Players' Championship and losing in the final of the 2019 Champions Cup.
The team was set to represent Canada at the 2020 World Women's Curling Championship before the event got cancelled due to the COVID-19 pandemic.
[20] Birchard returned to the bubble for a third time in April 2021, along with her women's team to play in the two only Grand Slam events of the abbreviated season.
Through the round robin, the defending Scotties champions posted a perfect 8–0 record, earning a spot in the playoffs.
They then lost in the seeding round to New Brunswick's Andrea Crawford, meaning they would have to win three straight games to defend their championship title.
[30] At the 2022 Champions Cup, the team secured their third Grand Slam title as a foursome with a 10–6 victory over Gim Eun-ji.
[34] Team Einarson was chosen to represent Canada at the 2022 Pan Continental Curling Championships where they qualified for the playoffs as the second seeds with a 7–1 record.
[37] In December, they travelled to Japan to compete in the 2022 Karuizawa International Curling Championships where they lost in the final to Kim Eun-jung.
[40] They then won both the 3 vs. 4 game and the semifinal over Nova Scotia and Northern Ontario respectively to reach another national final where they again faced Jones.
[46] Team Einarson reached the quarterfinals in their first event of the 2023–24 season, falling to Serena Gray-Withers at the 2023 Saville Shootout.
They had three semifinal finishes and one quarterfinal appearance before missing the playoffs at the 2024 Players' Championship, breaking their streak of qualifying at the previous twelve Slams.
Once there, however, they lost both their games to Team Homan and Manitoba's Kate Cameron, eliminating them from contention and ending their chance of a record setting fifth straight Scotties title.
[50] Following the event, in March, it was revealed that Harris had been provisionally suspended for up to four years for testing positive for Ligandrol, a banned substance.
