Throughout the First World War, Eaton employees on active service continued to receive salaries (either full or half pay, depending on their marital status). As a result, some 3,300 enlisted men received more than $2 million during this time. Because of Germany's involvement in the war, Eaton ordered a boycott of all German companies, and it was not until 1924 that the company resumed buying operations with Germany.
Margaret Wilson Eaton was married to Timothy Eaton who is remembered as the founder of the T. Eaton Co. Limited department store. This plaque was erected in memory of Margaret Eaton.
