She set the women's world record for constant ballast by diving to a depth of 88 metres (289 ft) on one breath, in April 2007 in the Cayman Islands. As captain of the Canadian freediving team at the 2004 AIDA World Freediving Championships, the women's team (consisting of Cruickshank, and teammates Jade Leutenegger and Jessica Apedaile) took first place.
In May 2006 she was the subject of media attention as one of David Blaine's 'Drowned Alive' safety divers (as a member of the Performance Freediving team). Along with Martin Stepanek she dove into David Blaine's water filled sphere to rescue him from drowning during his failed 9 minute breath-hold stunt.
