U2 Summative By marselli250 1914 Canada's Declaration of War I'd give this a +1. I say this because even though we had wins, we had many, many deaths. Period: 1914 to 1929 U2 Summative 1915 Women Start Working +2. During this time women were brought into factories to help with supplies. 1915 Indigenous Joining WW1 +2. The Indigenous soldiers were seen as excellent snipers.
