September 12, 1910

UTS opens its doors for the first time to 325 students - all boys.


In September 1914, UTS was only four years old, but soon its students, alumni, and masters began to enlist in the Canadian Forces, eager to fight in the war that was unfolding in Europe. Over the next four years, nearly four hundred members of the UTS community would serve in the First World War, leading one former student to comment that “if you want to meet a UTS Old Boy, you have to hunt around London or France - not many left in Toronto.” Of those four hundred, sixty-three would not return.



To honour their sacrifice, the UTS First World War Commemorative Project was commenced by Dr. Paul Moore, a long-time UTS Faculty member as part of UTS' Centennial celebrations in 2009-2010. The vast majority of the material presented here is the direct consequence of his research and dedication. A number of Alumni contributed to the translation of Dr. Moore's research into an online document, with this side spearheaded by Morgan Ring '07 and Peter Wills '07. Diana Berbece '08, Jong Park '07, Matthew Yu '07, and Emil Nachman '07, and Anthony Mok '07 also contributed to this project's development.
