In 1909, Joseph Kilgour, President of the Canada Paper Company, established one of Bayview's first country estates, south of Lawrence Avenue. The sweeping two-hundred acre Sunnybrook Farms property was highlighted by a stone gated entry and a magnificent residence with oak paneling, an open gallery and beamed ceilings that created the flavour of an English country manor. Kilgour also had a love for fine horses. One of his favourite pastimes was riding his prized hunter 'Twilight' across the open fields and wooded hillsides on his property.

The Kilgours had no children, so after Joseph's passing, his wife Alice, donated Sunnybrook Farms to the city in 1928 to be used as a park. Today, The Sunnybrook Health Science Centre stands in the place of Kilgour's country residence, while the Kilgour barns were preserved and currently serve as a public riding school and stabling for the Metropolitan Police. The fields are now used for sports and recreation.
