James Tiberius "J.T." Yorke (c. 1989-2006) was a senior (Grade 12) at Degrassi Community School at the time of his death. Throughout his years of attending Degrassi, he was ultimately known as the class clown, due to his great sense of humor. He was the kind of kid everyone knew and loved, and he could light up a room with his presence. Despite his comedic ways, J.T. had to undergo numerous obstacles such as dealing drugs and putting his baby up for adoption.
J.T. was best friends with Toby Isaacs. He was also good friends with Emma Nelson, Manny Santos, Liberty Van Zandt, Sean Cameron, Danny Van Zandt, Derek Haig, and Paige Michalchuk. He had conflicts with Spinner Mason and Jay Hogart, but was on good terms with both of them at the time of his death. He was in love with Liberty Van Zandt. His life was cut short at only seventeen years old, as he was stabbed and killed outside of Emma's house during Liberty's 17th birthday party by Drake Lempkey, a very drunk Lakehurst Secondary School student. He was portrayed by Ryan Cooley.
