On November 29, 1989, the college’s coat-of-arms was officially heralded under the authority of the Chief Herald of Canada making Lady Eaton one of less-than-100 educational institutions in the country to have such an honour.  

The Lady Eaton College Coat of Arms was designed by a group of students, faculty, alumni and staff to represent the College’s history, scholarship, spirit and uniqueness, as well as its ties to the university. 

The winter 1990 edition of Alumni Magazine states, “The committee presented artistic submissions to the Canadian Heraldic Authority in Ottawa to make sure the armorial bearings would be officially heralded. The two books in the crest represent its academic aspects: the gaining and application of knowledge. The sumac branches reflect the spirit of the College and its members’ ecological awareness. The barrulet at the top of the shield represents the drumlin and echoes the water shown on the University’s logo. Champlain’s sword rising from the river and resting at the base of the drumlin represents the College’s ties to the University, while the Tudor rose (at the center of the sword) signifies the College’s relationship to Flora McCrae Eaton and the Eaton family. Sapientia et Humanitas has two interpretations: wisdom and humanity and humanity through wisdom.”
