Hutson, the winner of the Calder Trophy last season as the League’s best rookie, got hugs and high-fives from all his teammates and coaches after the announcement.
The 21-year-old recorded 66 points (six goals, 60 assists) in 82 games last season. He broke Chris Chelios' Canadiens record for most points by a first-year defenseman (64 in 1984-85).
He was Montreal's second Calder Trophy winner in the expansion era (since 1967-68) after goalie Ken Dryden, who won the award in the 1971-1972 season.
Canadiens general manager Kent Hughes commented on the contract after it was announced on Monday.
"I had a conversation with Lane over the weekend, and he had talked about his view on things," Hughes said. "It struck me he wanted to make sure we understood how much he wanted to be here and how hard he was going to work. … The kind of person he is, how committed he is to being his best version of himself, but also being the best version of a teammate.”
The Canadiens play their home opener against the Seattle Kraken at Bell Centre on Tuesday (7 p.m. ET; RDS, TSN2, KONG, KHN) after going 2-1-0 on a season-opening three-game road trip.
