It is with profound sadness that we announce the passing of our dear friend, Michael Mostyn, z”l, a dynamic leader, a passionate advocate, and above all, a genuine mensch. Michael’s life was dedicated to tikkun olam—repairing the world—a mission he embraced with every position he held and with every life he touched.

As the CEO of B’nai Brith Canada since 2014, Michael’s vision and leadership revitalized the organization, transforming it into a formidable voice in combating antisemitism and defending the rights of the Jewish community across Canada. His passion for justice was deeply rooted in Torah values, and whatever he did in life, was undertaken with tremendous respect and unwavering integrity. 

Born to a family committed to Jewish tradition and values, Michael was a staunch defender of Am Yisrael and his faith guided him in everything he did. His presence was not limited to boardrooms or podiums; he was equally at home at synagogue and public events, sharing a warm smile and a thoughtful word with friends and community members alike.

Michael was not only a dynamic leader and visionary, but also a wonderful listener. His ability to hear the concerns and needs of others, combined with his savvy skills as a barrister and public servant, enabled him to effect real change. Whether standing up to hate or standing up for the vulnerable, Michael embodied the Jewish value of pursuing justice —“Tzedek, tzedek tirdof.”

Under Michael’s leadership, B’nai Brith’s Annual Audit of Antisemitic Incidents became a vital resource for addressing hate in Canada, and his advocacy in the courts and with governments strengthened protections for our community and other marginalized communities. Yet, despite his public accomplishments, those who knew Michael personally will remember his kindness and compassion: the quiet moments when he extended a helping hand, shared words of encouragement, or simply listened with his whole heart.

He was awarded many accolades during his lifetime, including the Queen Elizabeth II Diamond Jubilee Medal and the King Charles III Coronation Medal, but his distinguished legacy remains in the countless lives he touched and the world he helped make more just and compassionate.

Michael is survived by his loving family, Ella, Benjy, and Bella, who were his greatest source of pride and joy. He was a beloved and adored son and brother to Sheila and Alan and to Matthew and Sari. To them and their families, he was their giant pillar of strength, courage and love. To his friends and colleagues, he was an infinite source of inspiration. And to the Jewish community, he was a protector, a defender and a beacon of light. 

His B’nai Brith family will miss him dearly and his indomitable spirit will remain in our hearts eternally. We will carry the torch with pride and honour in his name!

Michael Mostyn’s memory will forever be a blessing, and his impact will continue to be felt in so many different ways, in the years to come. May we all honour his legacy by emulating his steadfast courage, unconditional kindness, and commitment to tzedakah and chesed.

Yehi zichro baruch—May his memory be a blessing.
