She moved to London in 2003 forming the theatre company, Suspect Package with fellow Canadian actor Trevor White ( Downton Abbey/ Episodes), where their productions received critical success. Evening Standard review for "Problem Child": ' It is impossible to maintain a detached reaction to the Suspect Package company's provocative production, largely due to the impressive Samantha Coughlan's sympathetically psychotic performance'.
