About Us
An artistic Infusion
COSA Canada invites you to join us in its vibrant and personal experiences.
We are excitedly nurturing the artist-audience-circle, highlighting Canada’s emerging vocal talents
while enriching everyone's quality of life and well-being.
We founded COSA in 2006 and incorporated in 2009 to create essential experiences and training for Canada’s thrilling musical talents. We grew enthusiastic audiences each step of the way, event after event, and
excitement after excitement.
Through our many performances, genres, and formats - we are making all the difference in lifting lives.

Mission
COSA GROWS STORYTELLING
with SINGING EXCITEMENT!
Our vibrant, diverse performers ignite your imagination through thrilling concerts and performances. We offer heartwarming emotions and send you soaring across genres and cultures. Initially performing in traditional forms, our singers are letting loose with Broadway, pop, and styles for miles. COSA opens pathways for artist-citizens in the world. We create great experiences for each other. We sing the universal stories you want to hear, and stories unimagined before - you will want to remember. We welcome you to our exciting circles of singing.
