The Ontario Sires Stakes (OSS) Program was established over 40 years ago, in 1974 to promote the breeding of Standardbred horses in Ontario. This program provides economic incentives for breeders, owners and trainers to breed, buy and race horses in Ontario. Horses eligible for this program are the best racing horses that Ontario has to offer! You can see these horses race throughout the tracks in Ontario within their respective division. The OSS is part of the Standardbred (SIP) component of Ontario’s Horse Improvement Program (HIP), established in 1968.

Information & Highlights
What is... Ontario Sired?
A horse that is the offspring of a recognized ONTARIO SIRE shall be eligible to be registered as ONTARIO SIRED and thereby eligible to be nominated to the ONTARIO SIRES STAKES. A horse does not need to be foaled in Ontario to be registered as ONTARIO SIRED. A horse can be both ONTARIO SIRED and ONTARIO BRED and be eligible for incentives attached to each status.
Ontario Sired Benefits
The Ontario Sires Stakes Program is a series of races for 2- and 3-year-old horses sired by eligible ONTARIO SIRES and nominated and sustained to the Ontario Sires Stakes Program. Benefits include:
Benefits for Breeders
- Ontario Bred Rewards
Ontario Bred Rewards are paid to the owners/lessees that enrolled the mare in the Ontario Resident Mare Program for that foaling year. Ontario Bred Rewards on OSS earnings are capped at $1M. Ontario Bred Rewards for selected Open Stakes are capped at $130K with an individual cap of 20% of Open Stakes earnings per horse. These Rewards will be paid on a pro-rata basis in January of the following year.

Under the Breeders’ Enhancement Program, administered by the Standardbred Breeders of Ontario Association (SBOA), breeders will receive approximately $3M per year from 2015 to 2018 in various breeders’ incentives. Foals must be both ONTARIO SIRED and ONTARIO BRED to benefit from this program. Additional information can be found at www.standardbredbreeders.com or by calling 519 833-2861.

Eligibility for the Ontario Sires Stakes Program
To be eligible to the OSS, foals must be sired by a stallion standing in Ontario and registered with the OSS Program for the breeding year. A nomination payment is due in the horse’s yearling year. To maintain its eligibility, sustaining payments are due in the two- and three-year-old seasons if the horse is expected to race in the OSS.
- Stallion Owners (or Stallion Lessees) must hold a current, valid AGCO licence, register the stallion with the Program as an ONTARIO SIRE for each breeding season in which he is eligible, and pay all fees required to register. The deadline for applying to register a stallion without a penalty is January 15th of the breeding year. A stallion must be owned or leased by an Ontario resident to be registered with the Program.
- Owners of Ontario Sires Stakes Eligible Horses must nominate and sustain the eligible yearlings, two-year-olds or three-year-olds with the Program, and meet all eligibility requirements.
