On February 15, 2015, Jokinen, along with Brendan Leipsic and a first-round draft pick in 2015, were traded to the Toronto Maple Leafs in exchange for Cody Franson and Mike Santorelli. He wore number 11 in Toronto as opposed to his regular number 13, out of respect for the Maple Leafs' great Mats Sundin, saying, "There's only one No. 13 for the Maple Leafs and that's the way it should be."
