In beginning his collegiate career in the 2013–14 season, Kerfoot made his debut for Harvard and registered an assist in a 3–0 victory over Bentley University on October 26, 2013.

Having completed his four-year collegiate career, Kerfoot chose not to sign a contract with the NHL organization that drafted him, the New Jersey Devils, rendering him a free agent.

[11] Having rejected the Devils due to their prospect depth at the centre position, Kerfoot received NHL-wide interest including from his hometown club, the Vancouver Canucks.

[13] After an impressive training camp with the Avalanche, Kerfoot played in a scoring-line role throughout the pre-season and secured a spot on the opening roster for the 2017–18 season.

He registered his first NHL point with an assist on Tyson Barrie's game-winning goal in a 4–2 victory over the New York Rangers at Madison Square Garden on October 5, 2017.
