The Late Yearling Nomination deadline for the Ontario Sires Stakes (OSS) program, is August 2, 2022.

Please submit your nomination payment by mail, postdated no later than August 2, 2022, or through the OSS online payment system by midnight on that date.

The late fee is $500 and nominates foals of 2021 to race in 2023 and 2024. No nominations will be accepted after August 2, 2022.

All yearlings must be registered at time of nomination and Standardbred Canada requires that the DNA and microchipping be completed before the foal is registered. To register your foal online with Standardbred Canada click here.

2021 foals not nominated as Yearlings in 2022, will be subject to a fee of $1500 (subject to change) if they are sustained to race as a two-year-old in 2023.
