What does Belinda Stronach do now?

Belinda Stronach is chairman, president, and chief executive officer of The Stronach Group, which now operates under the brand 1/ST (Casino.org). The company owns and operates horse racing tracks including Santa Anita Park and Gulfstream Park, along with gaming and real estate assets.

Current role at The Stronach Group (1/ST)

  • Stronach took full control of the racing and gaming side of the family business after a 2020 settlement with her father (Wikipedia).
  • She is also a board member of various Stronach family enterprises.

The implication: Belinda Stronach now runs a multi-billion-dollar operation that her father built, but she has made it her own by focusing on the racing and entertainment segments.

2026 and beyond

Her public plans beyond her current role are not detailed. She remains active in philanthropic work, including breast cancer campaigns (Wikipedia). The trade-off: while she stepped away from politics, she commands a corporate empire that keeps her in the public eye.

The upshot

Belinda Stronach’s corporate control over 1/ST means she directs the future of iconic tracks like Santa Anita Park and Gulfstream Park.

Did Peter MacKay date Belinda Stronach?

Yes. Peter MacKay and Belinda Stronach were in a high-profile romantic relationship while both were Conservative MPs. Their relationship was widely covered in Canadian media (CBC News).

Timeline of their relationship

  • The couple dated in the early 2000s, when Stronach ran for the Conservative leadership in 2004 (Wikipedia).
  • Stronach left the Conservative Party for the Liberals in 2005, which MacKay publicly criticized (CBC News).
  • They were never married.

Political impact of their split

The floor crossing and breakup created a lasting rift between two prominent Conservatives. MacKay later married, and Stronach moved on. The pattern: personal relationships in Ottawa can have real political consequences — Stronach’s defection weakened the Conservative minority and bolstered Paul Martin’s government.

Who is the father of Belinda Stronach?

Belinda Stronach’s father is Frank Stronach, the Austrian-born Canadian billionaire who founded Magna International, one of the world’s largest auto parts manufacturers (Goldsea).

  • He later founded The Stronach Group in 2011 with his daughter (Wikipedia).

Why this matters

  • Magna International shares inherited from her father’s foundation.

Comparison to father’s net worth

Frank Stronach’s net worth is estimated by Forbes and other outlets in the $1–2 billion range, though no current audited figure exists (BBC News). The catch: without a public disclosure, any exact number is speculative.
