The OSS Program Coordinator will be mailing out two-year-old sustaining forms in the coming weeks. If you purchased an OSS eligible yearling last year, please ensure that the transfer is completed as soon as possible so the correct owner receives the notice.

Please contact the Standardbred Canada membership services department for assistance.

The 2-year-old sustaining fee for 2022 is $600, and payment must be received via the online form, or hard copy received by OSS postmarked no later than March 15, 2022.

Yearlings not nominated to the OSS in 2021 may be nominated in 2022 by paying a late nomination fee. The late nomination fee is $1500. This fee is in addition to the $600 sustaining fee. Both fees are due on March 15, 2022.

This also serves as a reminder that 3-year-old sustaining notices have already been mailed. If you did not receive one, please visit the OSS website, or download the form below. The three-year-old sustaining fee is $800 and is due February 15, 2022.
