"I just have to take responsibility and be more responsible," Chan told reporters Thursday in Vancouver, site of the ISU Four Continents from Feb. 2-8, 2009.
"I have to be a role model, like he [Buttle] was."
Buttle, the reigning world champion, retired Wednesday from competitive figure skating, leaving Chan as Canada's top medal contender in men's singles just 17 months shy of the Vancouver Olympics.
"He is a huge up-and-coming star for Canada," Buttle said. "We're going to see great things from him, as well as the other guys."
