Canadian Women’s Sex-Based Rights (caWsbar) is an anti-transgender organization that is part of the sex segregationist movement.
Background
The anti-trans organization caWsbar began their online presence with a press release by pseudonymous founding member “Karen Finlay” in December 2019. While their website contains many stock photos of non-white people, the organization’s members are almost exclusively white.
It is part of a network that focuses on several sex segregationist aims, including opposition of transgender athletes and accommodations for transgender prisoners.
Anti-trans activism
On April 22, 2021, several signatories on a letter from a coalition called Global Activists Against Violations by Pornhub also identified themselves as affiliated with caWsbar.
On March 8, 2024, caWsbar’s event Reality Based Women Unite was held in Toronto. The event was significantly funded by right-wing civil liberties group The Democracy Fund and featured Trish Oliver, Amy Hamm, April Hutchinson, Eva Kurilova, Raine McLeod, Heather Mason, Meghan Murphy, and Linda Blade.
On March 8, 2025 caWsbar’s event Reality Based Women Unite was held in Calgary. The event featured Liza Vespi, Maureen Sullivan, Drea Humphrey, Ghislaine Gendron, Trish Oliver, John Carpay, Amy Hamm, Heather Mason, and Kara Dansky.
On March 7, 2026, caWsbar’s event Reality Based Women Unite was held in Montreal. The event featured Linda Blade, “Genevieve Gluck,” Alexandra Houle, Heather Mason, Anna Slatz, and Natasha Totino.
