The BBBST ! AM Initiative

We recognize the importance of language, and its impact on inclusivity and identity erasure. We acknowledge how our organizational name re-enforces the gender binary and fails to honour Trans, non-binary and gender diverse identities and we are actively advocating for change. We welcome mentors and mentees who are 2SLGBTQIA+, and we are proud to have 2SLGBTQIA+ staff leading our ! AM initiative – developing intentional and inclusive programs for mentees and mentors of the community.
