In 2003, she formed a comedy troupe called "Women Fully Clothed" with four other Canadian comedy artists. Fellow cast members Kathy Greenwood, Robin Duke, Jayne Eastwood, Teresa Pavlinek and McGrath perform sketches about situations ordinary women face every day. One reviewer considered that "Although all five comedians have performance skills in spades, Kathryn Greenwood and Debra McGrath are standouts, ... the latter for her dancing skills. ... McGrath cuts a mean rug in her tap shoes, and her monologue in the routine about being on the phone with her mum and granny hit very close to the bone." McGrath left the troupe in the first half of 2009.
