[1] Wheatcroft made her Scott Tournament of Hearts, the Canadian women's national championship, debut in 1987 as a third for Pat Sanders.

Sanders, Wheatcroft, and their British Columbia team won the 1987 Scott Tournament of Hearts, defeating Kathie Ellwood in the final.

At the World Championships that year, the team won the gold medal defeating Germany's Andrea Schöpp in the final.

In 1989, Wheatcroft moved to Julie Sutton's team and again qualified for the Tournament of Hearts, where they would lose in their first playoff game.

In 2005, she was picked up by that year's Hearts champion Jennifer Jones to replace Cathy Gauthier, and she moved to Winnipeg, Manitoba, to play with the team.
