Thornton was nominated for a Dora Mavor Moore Award for her direction of the 2001 production. In April 2000, Thornton became the artistic director of the Rhubarb! Festival in Toronto.

Thornton was heavily involved in launching Equity in Canadian Theatre: the Women’s Initiative with the Playwrights Guild of Canada and the Professional Association of Canadian Theatres. Equity in Canadian Theatre focussed on addressing the gender imbalance in leadership positions in Canadian theatre. Thornton served as co-head of the initiative. While Thornton was Nightwood's artistic director, she directed several productions including Véronique Olmi's Mathilde, Polly Stenham's That Face, Jennifer Tremblay's The List, Margaret Atwood's The Penelopiad, Anupama Chandrasekhar's Free Outgoing, and Mary Vingoe's Refuge. In 2019, Thornton left Nightwood to become the artistic director of the Royal Manitoba Theatre Centre. Thornton is the first female artistic director of the RMTC.
