The Canadian reached a career-high ranking of No. 87 in 2012 and won 10 career titles on the ITF level. Her best Grand Slam performances were second round showings at the Australian Open (2012) and the Wimbledon Championships (2011). Dubois was also named the ‘Female Player of the Year’ by Tennis Canada on two occasions (2005, 2007).

Heading into her final week as a professional, she ranks at No. 268 in singles and a doubles ranking of 690. Her final singles title was at the ITF event in Troy two years ago.
