Pride Toronto is apologizing for a "history of anti-blackness" within its organization and regrets the way the Black Lives Matter Toronto pride parade protest was handled earlier this summer.

The executive director of Pride Toronto has resigned amid allegations he sexually harassed staff members, left "controlled substances" in the organization's headquarters and was abusive, manipulative, racist, sexist and transphobic, according to an internal email allegedly written by staff members obtained by Global News.

Toronto's annual Pride Parade will be dedicated to the victims of the Orlando nightclub shooting after 50 people were killed and 53 more were wounded when gunfire erupted early Sunday morning.
