Singh – who had been announced as part of the production in April – has exited the work due to scheduling conflicts, according to press representatives for the production. In her absence, newcomer Monika Schneider has assumed the central role in Lentini's exploration on caregivers and a patient's right to die.

A graduate of Toronto's Ryerson University, Schneider recently presented her solo show, Nevil, at Ryerson's New Voices festival and fringe festivals throughout Canada.

Lentini, a Lillian Hellman Prize in Drama winner, penned The Euthanasist, which centers on "care giving, devotion and losing one's self in a self-imposed torture of the day to day," according to press notes. Schneider portrays the mysterious euthanasiast whose testimonials illuminate her relationship to the living and those who wish to die.

The Euthanasist officially opens May 31 and will play a limited engagement through June 15.

Alan Miller stages the drama with set design by Adam Dugas and lighting design by Diana Kesselschmidt. Paul Cantelon, who scored the films "Everything Is Illuminated," "The Other Boleyn Girl," and "The Diving Bell and the Butterfly," has penned original music for the production.
