Payne was born in Barbados and spent her early childhood in Christ Church, Barbados.[3] As a young child, her parents, Ina and Clarence Payne, moved to New York City for school and work, leaving her behind in Barbados. In 1970, when Payne was nine, she rejoined her parents and the family settled in Toronto, Ontario, and later in Concord, Ontario.[3][4][5] She attended Vaughan Road Collegiate Institute in Toronto, where she blossomed into a star sprinter, becoming an Ontario provincial champion in both the senior 100 metres and 200 metres in 1979.[3][6]
Payne began competing for Canada at the 1979 Pan American Games, where she won a bronze medal with the 4 × 400 metres relay team. In 1981, she was a member of the Americas 4 × 400 metres relay team that took bronze at the IAAF World Cup in Rome. The following year, at the Commonwealth Games, she won a silver medal with the Canadian team in the 4 × 100 metres relay, and was a 400 metres semi-finalist.
Payne won a silver medal in the 200 metres, at the 1983 Universiade, and helped Canada win silver medals in both the 4 × 100 and 4 × 400 metre relays. That year, she also won a silver medal in the 4 × 400 metres relay at the Pan American Games. She competed in the inaugural World Championships two weeks earlier. At the championships, held in Helsinki, she finished fifth in the 400 metres – the best performance by a non-European athlete in the discipline, breaking the existing Commonwealth record with a time of 50.06. She also teamed up with her Canadian compatriots in the 4 × 100 and 4 × 400 metres relay events, where they finished fifth and fourth in the finals, respectively.
Payne helped the Canadian 4 × 400 metres relay team win a gold medal, and finished fourth in the individual 400 metres race, at the 1986 Commonwealth Games. In 1987, she won her second silver medal in the 4 × 400 metres relay at the Pan American Games. A few weeks later, she reached the semi-finals of the 400 metres at the World Championships, and along with Crooks, Killingbeck and Richardson, she took Canada to the fourth position in the 4 × 400 metres relay. The team reunited for the 1988 Summer Olympics in Seoul, but failed to finish in the relay final. She was a semi-finalist in the individual 400 metres race. Shortly after the Olympics, she retired from track and field.[1]
