During training camp for the 2014–15 season, McDavid was named the captain of the Erie Otters. McDavid had a strong start to the season before breaking his hand in an on-ice fight on November 11, 2014. At the time, McDavid was leading the OHL in points, having scored 16 goals and 35 assists in 18 games. McDavid missed six weeks of play as a result of his injury, returning to the ice to play for Canada at the 2015 World Junior Championships. He rejoined the Otters on January 8, 2015, scoring a goal in a 4–3 loss against the Sarnia Sting. In the 47 games that McDavid played with the Otters during the 2014–15 regular season, he registered 44 goals and 76 assists, finishing third in OHL scoring. McDavid had a dominating performance during the OHL playoffs, scoring 21 goals and 28 assists and leading all players with 49 points (in comparison, Sault Ste. Marie Greyhounds player, Nick Ritchie, was second in playoff scoring with 26 points). He was awarded the Wayne Gretzky 99 Award as playoff MVP despite the fact that the Erie Otters were eliminated in 5 games in the OHL Championship by the Oshawa Generals. New York Islanders captain, and former Oshawa General, John Tavares, was in attendance during Game 3 of the 2015 finals and said of McDavid: "I don't think I've ever seen anyone with that kind of acceleration — you think he's at top gear and there just always seems to be another level."
