The Canadian Medical Association Journal published a letter by a Montreal-based pediatric surgeon Monday, which called the hijab an “instrument of oppression.”

The Canadian Medical Association Journal has officially retracted a letter to the editor which called hijabs “instruments of oppression,” after a swift outcry from members of the Canadian Muslim community.

The opinion piece, written in response to a photo published in the journal depicting two girls reading together, one of whom is wearing a hijab, was criticized online by Muslim women in medicine.
