Usher 1F Collaborative Comes to Canada!

Usher 1F Collaborative has had a presence in Canada from the start. Usher 1F families in Toronto, Ottawa, and Newfoundland have worked alongside us, and one of our researchers, Vincent Tropepe, is at the University of Toronto. Also, one of our RUSH 1F natural history study sites is at the University of Toronto Hospital for Sick Children, Ajoy Vincent MBBS, MD, Principal Investigator.

Without the ability to issue Canadian tax receipts, though, our fundraising in Canada was limited. In 2022, we made the decision to incorporate  in Canada, and we became an official registered charity in Canada in March 2023.

Through Usher 1F Collaborative Canada, we now accept donations in Canadian dollars and issue Canadian tax receipts!


As we grow and increase our efforts in Canada, we invite you to join us. We love our volunteers, and no gift is too small.
