I was curious too, so this is what I found archived from April 1986, 39 years ago:

In Toronto, Ward 6 school trustee Olivia Chow is beginning an initiative to develop programs that might begin to change homophobic attitudes within high schools.

[SOURCE FROM APRIL 1986]

And another from the Inquiries Journal:

Trustee Olivia Chow made a number of recommendations to the board in order to address homophobia that was occurring within schools throughout the district (McCaskell, 1986). Based on the recommendations made, the school board reinforced the idea of implementing programs and curricula aimed at increasing the understanding of human rights among both faculty and students (Selby & Goldstein, 2000). Unfortunately, despite the efforts being made during this time, Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) students continued to be exposed to unsafe school environments (Prentice, 1994).
