"That's between my agent and [general manager Kyle Dubas]," Nylander told TSN on Tuesday. "They're talking about it, so I'm not really into that right now. Once it gets closer to the season, I think I'll be more dialed [in]. I mean, Kyle says it's going to take some time, so I'm not too stressed about it."
The 22-year-old had 61 points (20 goals, 41 assists) playing the final season of a three-year, entry-level contract he signed Aug. 18, 2014, after he was the No. 8 pick in the 2014 NHL Draft.
He can sign a contract of up to eight years, or he could sign a shorter-term deal that would keep him a restricted free agent after it expires.
"Of course I'd want long term, that's what I'd want to do," Nylander said Wednesday. "But we'll take it slow, day by day, and see what happens."
Nylander said he did not anticipate the contract being a problem entering training camp in September.
The Maple Leafs this offseason signed free agent center John Tavares to a seven-year contract worth $11 million per season and are negotiating a contract extension with center Auston Matthews, a frequent linemate of Nylander.
