Throughout the 1990s, the introduction of women into the combat arms increased the potential recruiting pool by about 100 percent. It also provided opportunities for all persons to serve their country to the best of their abilities. Women were fully integrated in all occupations and roles by the government of Jean Chretien, and by 8 March 2000, even allowed to serve on submarines.
