Bouchard started playing tennis at the age of five and was a member of Tennis Canada's National Training Centre in Montreal. She attended The Study school in Westmount. At age 12, she moved to Florida with her mother to be coached by Nick Saviano, where she met one of her best childhood friends, tennis player Laura Robson. From that time on, she was nicknamed "the chosen one" by her siblings. Her father established a limited partnership called "Tennis Mania" to support Eugenie's career. He and two investors contributed money to the partnership in exchange for 10 percent of Bouchard's future earnings when she would become a professional tennis player. In August 2013, a court ruled that the partnership has no legal claims as Eugenie, then a 9-year-old, could not have reasonably agreed to giving away parts of her future earnings. Her father had argued that the money he had put into the partnership before Eugenie turned pro was a business loss which would have meant a tax benefit for himself.
