In his first season with the club, they finished top of the league and won the Grand Final against Featherstone Rovers to win the Championship for the first time since 2004.

[citation needed] Kay was the first-ever signing to play for the newly formed Canadian club, Toronto Wolfpack, for their inaugural season in 2017.

Unfortunately Kay suffered an extremely complex injury in the first week of the play-offs, unfortunately that wasn't the first of the bad news for Toronto Wolfpack as they would later fail to reach the Super league losing to London Broncos In the Million Pound Game.

Again Toronto Wolfpack would finish top of the table and at last gain promotion to Super League with Kay firmly in the mix.

[7] Kay played 25 games for Wakefield Trinity in the Super League XXVIII season as the club finished bottom of the table and were relegated to the RFL Championship which ended their 24-year stay in the top flight.
