The Ontario Sires Stakes (OSS) Yearling Nomination forms for foals of 2025 (OSS 55) have been mailed to all registered owners of Ontario-sired yearlings. Owners are reminded that yearling nominations are due before Friday, May 15 at 11:59 p.m. ET and all yearlings paid into the program must be registered at the time of nomination.

Standardbred Canada requires that the DNA and microchipping be completed before the foal is registered.

The OSS Yearling Nomination payment is required for your yearling to remain eligible to race in the OSS program as a 2-and 3-year old in 2027 and 2028. Sustaining payments will also apply.

A list of nominated yearlings can be found on the OSS website and will be updated Monday to Friday. Yearlings with multiple owners are kindly asked to communicate with ownership groups to ensure one payment is submitted to avoid duplicate payments.
