Ridgewell began playing hockey at the age of five, in Conquest, Saskatchewan. In her youth, she played for a variety of teams in towns in her native province, including a boys' team in Outlook and the Coteau Hills Coyotes, formed of girls from across the province. In Grade 10, she began playing for the Saskatoon Stars in the Saskatchewan Female U18 AAA Hockey League.[1]
From 2015 to 2019, she studied at Merrimack College in Massachusetts, in the United States, where she played for the Merrimack Warriors women's ice hockey program in the Hockey East conference of the NCAA Division I. She was named to the Hockey East All-Rookie Team in her first season with the university, making 694 saves in league play, the second-highest total in women's Hockey East history.[2] She was only able to play 14 games in the 2016–17 season, missing large parts of the year due to a concussion. She posted five shutouts in the 2018–19 season, a Merrimack record, and was named to the Women's Hockey East Second Team All-Star Team.[3] She was one of four women nominated for the NCAA's 2019 Hockey Humanitarian Award, the first women's player in Merrimack history to be nominated for the award.[4]
After graduating, she explored opportunities in Sweden and Switzerland, eventually signing her first professional contract with Djurgårdens IF Hockey of the Swedish Women's Hockey League (SDHL) in Stockholm.[5] In December 2019, she made 43 saves in a 3–1 victory over Brynäs IF.[6] She earned her first professional shutout in late January 2020, making 19 saves in a 2–0 victory over SDE Hockey.[7] She finished the season with a goals against average (GAA) of 2.03, the fifth best in the league, and a save percentage of .920, the seventh best in the league, as Djurgården were eliminated in the playoff semi-finals by HV71.[8]
In May 2020, she announced her return to North America, signing with the expansion Toronto Six in the NWHL, the second goaltender to sign with the team after Elaine Chuli.[9][10]
