In the introduction to her family photos from Harrington Lake, an official residence of Canada's prime ministers, Margaret Trudeau wrote, "These photographs were taken the summer before our son Michel was born — the summer of '75. They are an introduction to him of his family-to-be, and especially of his brothers, Justin and Sacha, who will always be a unique and special part of his life."
