His parents publicly announced their separation on May 27, 1977, when Trudeau was five years old, with his father having custody. There had been repeated rumours of a reconciliation in the public for many years afterwards, but his mother's attorney Michael Levine filed in Toronto to the Supreme Court of Ontario for a no-fault divorce on November 16, 1983, and finalized on April 2, 1984, with his father publicly announcing his intention to retire as prime minister on February 29 of that year. Eventually his parents came to an amicable joint-custody arrangement and learned to get along quite well. Interviewed in October 1979, his nanny Dianne Lavergne was quoted, "Justin is a mommy's boy, so it's not easy, but children's hurts mend very quickly. And they're lucky kids, anyway. " Of his mother and father's marriage, Trudeau said in 2009, "They loved each other incredibly, passionately, completely. But there was 30 years between them and my mom never was an equal partner in what encompassed my father's life, his duty, his country. " Trudeau has three half-siblings, Kyle and Alicia, from his mother's remarriage to Fried Kemper, and Sarah, from his father's relationship with Deborah Coyne.
