A granddaughter of the late newspaper baron Roy Thomson, as a young child Susan tagged along with a friend who was taking riding lessons and “loved it immediately.” She moved to England with her family in 1967, where she showed a bit and went foxhunting on a regular basis. After moving back to Canada, she rode out of Lorne Siegle’s barn in Oakville. She became a top competitor, enjoying success in the grand prix ring with Bricklin, Eli, Normandy, and Right Pass. She spent five years showing with legendary horseman and CET Olympic coach Carl Knee in the US, purchasing property in Cheltenham and developing Lothlorien Farm in 1974.

Susan and her husband, John, breed and raise top jumping prospects and standardbreds at Lothlorien Farm – home of the Cheltenham Gold Cup from 1977-1989 – and also run a show barn called Lothlorien South in Wellington, FL. Among her current top string of equine talent is Game Ready, Ariana, and Carlotta Singular. She co-owns five others with her daughter, Ariel, including Dixson, Fortis Fortuna, Lansdowne, and the latest, a six-year-old stallion named Dillinger.

What prompted you to invest in a sport which often promises very little financial return?

I do not consider my participation in the horse industry to be an investment. I have several other more profitable investments outside of the horse industry. I participate in the sport because it is my passion.
