With the lockdowns in Britain greatly affecting the availability of ice time, McKay temporarily relocated to Bradford in West Yorkshire during the summer of 2020, until the Scottish government revised its guidelines. McKay was named to the British team for the 2021 World Championships, but they were cancelled as a result of ongoing pandemic. Additional lockdown measures introduced by the Scottish government after Christmas resulted in her only being able to train four days a week, an hour and a half a day. Competing at the 2021 World Championships in Stockholm, McKay placed twenty-third. This result qualified a place for the United Kingdom at the 2022 Winter Olympics in Beijing.
