Princess Juliana and her daughters again took flight when the London Blitz began, this time to exile in Ottawa, Canada, where her younger sister, Margriet, was born and where Irene attended Rockcliffe Park Public School. As a teenager, she was dubbed by the Dutch press "the glamorous Princess of the Netherlands." During the war, the Royal Dutch Brigade (the formation of Free Dutch soldiers that fought alongside the Allies) was named for Princess Irene. This was continued after the war as the Regiment Prinses Irene.
