Orr sent a floral arrangement, as did Bettman and Daly, the Maple Leafs, Buffalo Sabres, Edmonton Oilers, New York Islanders, St. Louis Blues, Philadelphia Flyers, New Jersey Devils, Boston Bruins, Pittsburgh Penguins, New York Rangers, Los Angeles Kings, NHL Alumni Association, NHL Officials Association and the Hall of Fame, among others.
Perhaps the most touching message accompanied the flowers from former Maple Leafs defenseman Borje Salming, who lives in Sweden.
Salming cried about Gregory during a phone conversation with NHL.com earlier this week, saying that Gregory was like a second father to him and that he loved him.
During Gregory's illustrious career, one of his most notable accomplishments was bringing Salming and forward Inge Hammarstrom, another Swede, to the NHL in 1973. They were two of the first Europe-born players in the League.
"Thanks for everything you did for me and my family," the note accompanying Salming's flowers said. "You meant so much for me from Day One when I came over from Sweden. Your kindness and friendship will always be with me.
"From The Borje Salming family."
The message had some of Gregory's family members tearing up.
"Like I said, it's not a surprise," Poile said. "A special man."
