goals and two assists. Montreal Canadiens On June 24, 2016, Shaw was traded to the Montreal Canadiens during the 2016 NHL Entry Draft in exchange for two 2016 second-round picks. Three days later on June 27, Shaw came to a six-year contract agreement with the Canadiens worth $23.4 Million. The NHL suspended Shaw for three games for boarding Connor Hobbs during a preseason game played on September 26. Shaw scored his first goal with the Canadiens on October 13. Controversy ensued Shaw again when he slew footed Johan Larsson of the Buffalo Sabres at the end of the same game. The incident occurred towards the end of the game while the Canadiens had a 4–1 lead over the Sabres. Shaw was assessed a match-penalty, but did not receive any supplemental discipline after meeting with the Department of Player Safety. On March 13, 2018, Shaw checked Dallas Stars defenseman Greg Pateryn but was injured on the play. He injured his knee and suffered a concussion. As a result, Shaw underwent knee surgery and was expected to miss around six months to recover. Although Shaw missed the Canadiens training camp, he suited up during their 2018–19 regular season games. However, Shaw suffered a neck injury on December 31 in a game against the New York Islanders which kept him out of the lineup for 15 games. He returned to the Montreal bench on February 9, 2019, against the Toronto Maple Leafs. On February 26, 2019, Shaw scored his first career hat trick in an 8–1 win over the Detroit Red Wings.

On November 30, Shaw suffered a concussion during a game against the Colorado Avalanche and was placed on injured reserve. The injury effectively ended his season after 26 games when the team announced he would not return on February 29, 2020. On July 14, Shaw opted out of playing the remainder of the season (which had been suspended due to the COVID-19 pandemic), citing a preference to continue healing from the concussion. On February 9, 2021, Shaw suffered another concussion in a game against the Dallas Stars. On April 26, Shaw announced his effective retirement after being advised by the team doctors to discontinue his playing career due
