But Gladu's past comments and positions as a member of Parliament have raised questions about just how big the Liberal tent has become.
In 2021, she apologized for sharing "misinformation" about COVID-19 and vaccines during an interview with CTV News, and in 2020 said she would allow Conservative party members to introduce bills to restrict abortion.
Carney says there has been "no change" in the Liberal party's values, that the party "always will support the right of women to choose" and that Gladu offers expertise and new perspectives at a crucial time for the country.
