The Canadian Thoroughbred Horse Society (C.T.H.S.) was incorporated in 1906 under the Federal Live Stock Pedigree Act (presently called the Animal Pedigree Act – 1988) as a national breed organization to assist breeders of Thoroughbred horses in Canada. The National Office determines the requirements for Canadian-bred status of foals, maintains the Breeder Membership Roster for Canada, compiles statistics and represents Canadian Thoroughbred breeders nationally and internationally.
