of absence from the GSC in order to finish her degree, of which she received in 1910. In 1911, she went back and was given a permanent position at the GSC. It was not until 1970 that other women were granted the same. Before the departure of colleague Percy Raymond, she wrote two articles, both of which recorded new species of animals. Respectively, a new branchiopod and then a bivalve. Wilson faced significant difficulty being included in her colleagues' work after that. In 1916, during the First World War, Wilson's place of work, the Victoria Memorial Museum, was shut down and reoccupied as a war-time parliament. During this time, Wilson funded her projects with her own money, studying comparative anatomy and marine biology in Long Island, New York. Later, Wilson took part in the war-time effort on the home front, joining the Canadian equivalent of the Women's Land Army. At war's end in 1920, Wilson went back to the Victoria Memorial Museum, now working as an Assistant Paleontologist. She would further be promoted to associate geologist, in 1940. While working at the GSC, they did not allow women to work together with men during fieldwork. So Wilson created her own niche and did fieldwork at local sites in the Ottawa area, going on to eventually map over of the Ottawa St Lawrence Lowlands entirely on her own. For fifty years she studied the area on foot, by bicycle and eventually by car. The GSC published the results of her fieldwork in 1946 and her Geology of the St. Lawrence Lowland, Ontario and Quebec was the first major geological publication about the area. In addition to a comprehensive discussion of its geology, Wilson covered the area's economic resources, including building stone, sand, gravel and drinking water. Wilson's research into the stratigraphy and invertebrate palaeontology of the Palaeozoic strata of eastern Canada was significant, though her contributions to the field did not gain recognition until after her retirement. In Ontario, her focus was on invertebrate fossils during the Ordovician period, specifically sediments and fossils in the Ottawa Valley. In the Rocky Mountains and the Arctic, Wilson studied Ordovician fauna. During the Great Depression, however, Wilson had to switch her focus from Ordovician to Devonian rocks, to meet the growing demand of petroleum in Western Canada. One of her tasks was to identify and categorize all Paleozoic invertebrates for examination. As a result,
