Forwards Henrik Sedin and Daniel Sedin each is entering the final season of a four-year contract. The twin brothers, who turn 37 on Sept. 26, have played their entire NHL career for the Canucks.
Vancouver signed centers Sam Gagner and Alexander Burmistrov, defensemen Michael Del Zotto and Patrick Wiercioch, and goalie Anders Nilsson as free agents July 1. Center Bo Horvat, 22, remains a restricted free agent after he led the Canucks with 52 points (20 goals, 32 assists) last season.
Vanek said he began discussing a contract with Vancouver a few weeks ago. He signed a one-year contract with Detroit on July 1, 2016, and was traded to Florida on March 1.
"After you don't go that first week or the first couple days, I knew it was going to be a longer summer," he said, "but at the same time I wasn't worried about it. I knew what I could do and what I could bring, and in fact, if anything, training harder to prove people wrong. I still feel like I can have a lot of years left and score many goals."
Vanek has gotten to know Vancouver forward prospect Brock Boeser, who had four goals and one assist in nine games after making his NHL debut at the end of 2016-17.
"Brock is awesome. I am not going to say that I know him inside and out, but I skated with him quite a bit this summer and told him this morning, 'You know I might be joining you,' and he seemed fairly excited," Vanek said of the Canucks' first-round pick (No. 23) at the 2015 NHL Draft. "Who knows what that means, but he's a great kid. What I like about him is even in summer hockey or shinny hockey, if you tell him a little tip here or there, he is the type of kid who will listen and doesn't just shake his head and say, 'I know it better anyways.' He's very impressive."
Selected in the first round (No. 5) by the Buffalo Sabres in the 2003 NHL Draft, Vanek has 697 points (333 goals, 364 assists) in 885 games for the Panthers, Red Wings, Wild, Sabres, Montreal Canadiens and New York Islanders. He has 34 points (20 goals, 14 assists) in 63 Stanley Cup Playoff games.
