Ensemble Studio artists

The COC Ensemble Studio is an innovative artist development program for emerging Canadian opera professionals.

The company’s uniquely collaborative approach blends advanced study and practical experience through a multi-year program that’s individually tailored for each member. Artists receive intensive vocal coaching; language, movement and acting studies; as well as private masterclasses with renowned opera professionals. Ensemble singers perform and understudy mainstage roles, while Ensemble pianists participate in the preparation of the COC’s mainstage productions.

Members of the Ensemble Studio are the COC’s resident artists and important community ambassadors for the company. Through performances and collaborations with local schools and organizations, Ensemble members are often the first point of contact with opera for many; their ongoing participation in this area is integral to creating inclusive and welcoming opportunities for more people to engage with the art form.

Since 1980, nearly 230 young professional Canadian singers and pianists have acquired foundational opera experience through the Ensemble Studio. Former members include Ben Heppner, Krisztina Szabó, Emily D’Angelo, Claire de Sévigné, Gordon Bintner, Ambur Braid, Miriam Khalil, and Wallis Giunta, and David Pomeroy.

New members are chosen through a national audition process that culminates in the Ensemble Studio Competition for vocalists, the feature event of the COC’s annual fundraising gala Centre Stage.

**Due to ongoing public health restrictions, the public Ensemble Studio Competition and Centre Stage gala will not be held in 2021. However, national auditions for the 2022/2023 Ensemble Studio will take place, with further details below under “Applying for the Ensemble Studio.”
