The Calgary Philharmonic Orchestra has removed two of its musicians due to “deeply troubling comments posted online.”

The orchestra conducted a month-long investigation following its code of conduct and working alongside the Calgary Musicians Association union to look into the comments, without clarifying their content or author.

In a statement, the orchestra said that a “third-party investigator had concluded their work and that the organization was ‘taking action.'”

Calgary Philharmonic chief executive officer Marc Stevens said the orchestra will “address the behavior of two of our orchestra members,” without naming the musicians or elaborating on the behavior.

According to reports the comments that began the investigation were not disclosed.

However, according to Globe and Mail, screenshots were circulated online on Facebook, Instagram, and Reddit of a user from the orchestra using slurs against women and Black people.
