Smith first played midget hockey with the Markham Majors before playing with the North York Rangers of the Greater Toronto Major Midget Hockey League before he was selected 120th overall in the Ontario Hockey League's 2010 OHL Priority Selection by the Owen Sound Attack. In his first major junior season in 2010–11 with the Attack he finished with 16 points in 66 games.
After completing his OHL career with the London Knights, he was signed by the Dallas Stars to a three-year, entry-level contract on May 31, 2014.[1] He made his professional debut in the following 2014–15 season, after he was assigned by the Stars to their AHL affiliate, the Texas Stars. In 68 games with Texas, Smith contributed with 10 goals and 27 points in 68 games as a rookie.
In the 2016–17 season, with a rash of injuries suffered in Dallas, Smith received his first recall to the NHL on October 22, 2016.[2] He made his NHL debut with the Stars that night, skating on the fourth-line in a 3–0 loss to the Columbus Blue Jackets.[3] In his seventh game with the Stars, Smith scored his first two NHL goals in a 4–3 overtime loss to the Chicago Blackhawks on November 6, 2016.[4]
On July 11, 2017, the Stars re-signed Smith to a one-year, two-way contract worth $650,000.[5] In his first full season with the club, Smith recorded six goals and 11 points in 46 games, often finding himself as a healthy scratch.
On August 3, 2018, the Stars re-signed Smith to a one-year, $720,000 contract extension.[6] During the 2018–19 season, on December 6, Smith was claimed on waivers by the Boston Bruins.[7][8] Smith appeared in three games with Boston before he was re-assigned to Boston's AHL affiliate, the Providence Bruins, upon clearing waivers on December 19, 2018.[9] In playing out his contract in Providence, Smith was an offensive presence, contributing 40 points in 47 games.
As an impending restricted free agent, Smith was not tendered a qualifying offer by the Bruins, releasing him as an unrestricted free agent on June 25, 2019.[10] He signed a one-year, two-way contract with the Tampa Bay Lightning on July 8, 2019.[11]
Smith was one of the eight players called up to the Lightning for their training camp prior to the 2020 Stanley Cup playoffs.[12]
Following back-to-back championships with the Lightning, Smith began the 2021–22 season on the long-term injured reserve. After returning to health, Smith was claimed on waivers from the Lightning by the Detroit Red Wings on January 19, 2022.[13] He was assigned by the Red Wings to a conditioning stint with their AHL affiliate, the Grand Rapids Griffins, on January 23, 2022.[14]
On February 19, 2022, the Lightning reclaimed Smith from the Red Wings, again on waivers.[15]
In the following 2022–23 season, Smith remained within the Lightning organization, continuing with the Syracuse Crunch. While placing third in team scoring, collecting 37 points through 35 games, Smith left the Crunch as he was re-assigned on loan by the Lightning to the Vegas Golden Knights' AHL affiliate, the Henderson Silver Knights, on February 16, 2023.[16] He played out the season in Henderson, posting 5 goals and 16 points through 19 games.
As a free agent from the Lightning, Smith paused his career in North America and was signed to a one-year contract with Belarusian club, HC Dinamo Minsk of the KHL, on July 20, 2023.[17] In the 2023–24 season, Smith collected 4 goals through just 15 appearances with Dinamo before he was released from his contract and promptly signed for the remainder of the season with Chinese KHL outfit, Kunlun Red Star, on November 29, 2023.[18]
Returning to North America following the conclusion of his contract with Kunlun, Smith as a free agent leading into the 2024–25 season opted to return to the Syracuse Crunch organization, in signing a PTO on October 8, 2024.[19] His third stint with the Crunch was short lived as he was released from his PTO after only 7 appearances, registering 4 points, on October 29, 2024.[20] He continued in the AHL, on December 13, 2024, signing a tryout with the Bridgeport Islanders, the primary affiliate to the New York Islanders.[21]
