On January 28th 1916, the Manitoba legislature unanimously approved a bill to amend The Manitoba Election Act, which allowed women the right to vote within Manitoba.  This sparked a wave of change that soon gained the power of a Tsunami, transforming history. Not long after Manitoba’s gain, women in other provinces would also win the right to vote, first in Saskatchewan on March 14th 1916, and then Alberta on April 19th 1916.  The remaining provinces and territories were slower to make change. Many factors contributed to the early success of the women’s movement in the western provinces of Manitoba, Saskatchewan, and Alberta. The most important factors were the influence of a group of determined women,  the influence of the Woman’s Christian Temperance Union,  and the role of women in Western provinces.
