On June 24, 2013, Tourigny opted to pursue an NHL coaching career in accepting an assistant coaching role for fellow former QMHL coach Patrick Roy of the Colorado Avalanche.[2] After two seasons with the Avalanche as their primary defensive coach, Tourigny, seeking a head coaching position, resigned from his position on May 17, 2015.[3]

Following a 50–12–6 record and franchise record-breaking 106 points, Tourigny was named OHL Coach of the Year after coaching the 67's to a top place finish in the regular season and an Eastern Conference Championship, where the 67's set the OHL record for 14 straight wins to start a playoff since the conference playoff format was introduced. Tourigny followed that up with his second OHL Coach of the Year with a 50–11–1 record and 101 points prior to the OHL season being cancelled. The 67's set a franchise record for consecutive wins of 15 and yet another first-place finish in the OHL regular season standings.[9] For his efforts, Tourigny also took home the CHL Coach of the Year award.[10]
