A Winnipeg mother is filing a complaint with the Human Rights Commission after her son was told not to talk about homosexuality or bring his pride flag to school.

On Friday, Jennaya Isaac said her 12-year-old son and older brother were playing during recess at Calvin Christian School. They climbed to the top of the play structure – and Kaiden waved his pride flag.

“He was kicked out by the manager and told he wasn’t allowed to have the flag there because it’s a pride flag,” Isaac told CTV News in an interview. “I was just completely appalled that the director would do that.”

Isaac says Kaiden and his brother brought the flag to school anyway on Thursday – and says some classmates threatened to cut and burn the flag.

An email shared with CTV News sent by the school principal to Isaac says in part that the principal would be open “to discuss how we can find a positive path forward.”

CTV News has contacted the director about both incidents. He declined the interview request.

The school board president says this is an ongoing and emotional issue – and the school is working with consultants on this.

Isaac said she spoke with the human rights commission and was filing a formal complaint on Friday.

“I don’t think we should have to hide who we are,” she said.

CTV contacted a number of organizations affiliated with the school for comment, including Christian Schools Canada, The Prairie Center For Christian Education, Christian Schools International and the Manitoba Federation of Independent Schools. None of them have responded at the time this story was published.
