Pamela Anderson was born on July 1, 1967, in Ladysmith, British Columbia, Canada, to a working-class family of Barry, a furnace repairman, and Carol Anderson, a waitress. When Pamela was born, she was named the country’s Centennial Baby, having been the first baby born on July 1, 1967, the 100th anniversary of Canada’s official founding. Later, her family moved to Vancouver. She has a younger brother Gerry, born in 1971.
In 2004, Anderson became a naturalized American citizen, more than ten years after she first left Canada for a career down south. However, she retained her Canadian citizenship simultaneously.
