Pride Toronto is facing fire over an application from a controversial men’s rights group hoping to march in the annual parade this summer.

The non-profit organization that hosts the 10-day LGBTQ celebration said it has begun a dispute resolution process following “numerous” complaints it received about the wish of the Canadian Association for Equality (CAFE) to participate in the event.

Though Pride Toronto spokesperson Victoria Schwarzl refused to elaborate on the nature of that complaints, citing a need to “respect the impartiality” of the dispute process, CAFE has previously attracted harsh words from critics who identify it as anti-feminist.

CAFE denies the anti-feminist claims, but heated protests have erupted at some of the group’s events.

Michael Laxer, an activist who opposes men’s rights groups, said he has been encouraging people to fight CAFE’s inclusion at the parade because “they don’t reflect the values of Pride.”
