In the 2017–18 season, Martel began his fourth season with the Phantoms and was leading the team and AHL with 14 goals in 17 games before earning his first call-up to the Flyers on November 22, 2017.[5] He made his NHL debut that night against the New York Islanders,[6] and would play three more games after that before being sent back to the AHL.[7] In January 2018, Martel was selected for the 2018 AHL All-Star game; however, due to an injury, he was replaced by Oskar Lindblom.[8] Nearing the end of the 2017–18 season, Martel was named the Phantoms' 2017–18 IOA/American Specialty AHL Man of the Year for his work in the community.[9]
On September 22, 2018, Martel was claimed off waivers by the Tampa Bay Lightning.[10] In the 2018–19 season, on December 18, 2018, in a 5–2 win over the Vancouver Canucks, Martel scored his first NHL career point, assisting on a goal scored by Cédric Paquette.[11] Primarily serving as the Lightning's reserve forward on the roster, Martel served as healthy scratch to appear in just 9 regular season games for 2 goals.
On July 4, 2019, Martel was re-signed to a one-year, two-way contract extension with the Lightning. In the following 2019–20 season, Martel cleared waivers and continued in the AHL with the Syracuse Crunch, collecting 30 points in 52 games. On February 20, 2020, Martel was traded by the Lightning to the Florida Panthers in exchange for Anthony Greco.[12]
As a free agent from the Panthers, Martel was unable to attract an NHL deal before signing a one-year AHL contract with the Binghamton Devils, affiliate to the New Jersey Devils, on January 9, 2021.[13] In the pandemic delayed and shortened 2020–21 season, Martel added 6 goals and 14 points through 24 regular season games for Binghamton.
With Binghamton ceasing operations, Martel as a free agent signed a one-year AHL contract with hometown provincial club, the Laval Rocket, on 3 July 2021.[14]
Martel played with the Rocket for two seasons before leaving North America as a free agent to sign a one-year contract with Finnish club, HPK of the Liiga, on July 31, 2023.[15]
