Spyridoula (Speedy) Agathos began her teaching career in New York, where she taught English and Drama in Brooklyn and the Bronx. Returning home to Toronto in 1999, she joined Seneca College’s Continuing Education division, teaching English and Liberal Studies, a role she proudly continues today. That same year, she began her teaching career with the TDSB as a Long-Term Occasional teacher before being permanently hired in February 2000.
Throughout her career, Spyridoula has been dedicated to building vibrant school communities. She spent 17 years at West Humber Collegiate Institute teaching Drama and Dance before joining Thistletown Collegiate Institute in September 2017, where she has taught Drama, Dance, and English.
As education became increasingly complex, Spyridoula witnessed the growing challenges facing educators and public education. She realized that supporting colleagues required more than classroom leadership; it required strong union leadership, which inspired Spyridoula to become more actively involved in OSSTF. She recognized that protecting quality public education, advocating for fair and safe working conditions, and ensuring educators have a strong collective voice. As the educational landscape continued to evolve, she believed it was important to move from supporting the union to helping lead it, ensuring members’ voices are heard and represented with integrity, fairness, determination and collaboration. Her involvement reflects that commitment.
Spyridoula believes that leadership is rooted in service. She is passionate about protecting public education, strengthening member engagement, and ensuring that every member feels supported, valued, and represented.
Spyridoula has proudly served as Branch President at Thistletown Collegiate Institute since 2021, Spyridoula has also represented members as an AMPA Delegate, served on both the OSSTF Constitution/Steering Committee and the District Constitution Committee, and is currently on the Provincial Council Speakers’ Bank. She remains committed to strengthening the union, supporting members, and advocating for excellence in public education for current and future generations. In 2026, she became an Executive Officer, further strengthening her commitment to serving members and advancing the work of the union. Through collaboration, experience, and a deep commitment to solidarity, she is proud to continue serving the members of OSSTF.
