Key Change
is the COC’s new podcast, co-hosted by classical singer and culture critic Robyn Grant-Moran, a member of the COC’s Circle of Artists, alongside stage director, dramaturg and COC Academy graduate Julie McIsaac. Our bi-weekly episodes explore the operagoing experience from a variety of perspectives, offering a fresh take on today's opera issues with special guests from the opera field and beyond.

Episode 16: An Opera House Like No Other

Celebrating 15 years since its opening in 2006, the Four Seasons Centre for the Performing Arts in Toronto is a spectacular opera venue, community hub, and home to the Canadian Opera Company. This week, Robyn and Julie look back on the building’s origins, legacy, and future with three guests who all hold a very special connection to the performance space: Jack Diamond, lead architect of the Four Seasons Centre and co-founder of Diamond Schmitt Architects; Janice Oliver, who oversaw design and construction of the opera house; and world-renowned soprano Sondra Radvanovsky, a regular presence on the COC's mainstage.

Join us for a collection of inspiring, heartwarming, and hilarious stories as we mark a milestone for this home of Canadian opera.

As Executive Director of the Canadian Opera House Corporation, Janice Oliver oversaw the design and construction of the Four Seasons Centre for the Performing Arts, bringing years of intense planning into actuality. In her role, Janice coordinated a myriad of parties that included the design team, builders, acousticians, city officials and COC artists and team members. She fondly recalls the unique experience as “the best job I ever had” and has since been a loyal COC subscriber and President’s Council Patron, who can often be seen at various community programming and special events. In honour of her many contributions to the building of the space, Janice holds two named seats in R. Fraser Elliott Hall, one of which she has affectionately dedicated to the entire project team.


Soprano Sondra Radvanovsky is a globally celebrated artist whose exquisite voice and dramatic versatility has led to a remarkable range of repertoire that includes the title roles in Rusalka and Lucrezia Borgia, to Roxanne in Cyrano de Bergerac and the title role in Manon Lescaut. She is widely regarded as one of the premiere Verdi sopranos alive today, as well as one of the premiere interpreters of bel canto. Sondra has performed in every major opera house in the world, including the Royal Opera House, Teatro alla Scala, Opernhaus Zurich, and - of course - the Canadian Opera Company. Her signature interpretations of Verdi’s heroines include the title roles in Aida, Luisa Miller, Elisabeth de Valois in Don Carlo, and Amelia in Simon Boccaengra. In concert, she has sung with the Boston Symphony Orchestra, the Chicago Symphony Orchestra, and with the Bayerische Staatsoper, among many others. Her new talk show, Screaming Divas, hosted with friend and fellow soprano Keri Alkema can be seen on YouTube.

Robyn Grant-Moran (Métis) is a classical singer, writer, and a jack of many trades who, in 2018 met the requirements to call herself a Bachelor of the Fine Arts at York University. That same year, Robyn participated in the Performance Criticism Training Program with Generator Toronto where she learned that theatre criticism can be used to push for more inclusive spaces and champion voices less heard and often misunderstood; so of course she fell in love. Since then, she’s been published in Alt.Theatre and Intermission Magazine, won the Nathan Cohen Award for Outstanding Emerging Critic, and joined the Canadian Opera Company’s Circle of Artists, to name a few. Robyn currently resides in Tkaronto (Toronto), weathering the pandemic with her wee rat dog in a box in the sky.
