Like many women, Emily Murphy hated the thought of near-children being sent off to war, to be used as cannon fodder. To some extent, she blamed the problem of war on over-population. Thus, she looked upon France's fears of declining birthrate with equanimity, suggesting that if countries did not have enough young men to send to war, then war would cease, as countries would be highly motivated to keep the peace.

Listed below are some key positions Emily Murphy held in an effort to contribute to Canada's policy on war and peace.
