Visentin made his OHL debut for the IceDogs during the 2008–09 season. He played in 23 games, winning five. In the 2009–10 season, Visentin saw increased playing time, appearing in 55 games and winning 24.

Professional
At the tail end of the 2013–14 season, Visentin was recalled from Phoenix's American Hockey League affiliate, the Portland Pirates, and on April 12, 2014, he made his NHL debut in net with the Coyotes in a 3–2 defeat to the San Jose Sharks. During the Coyotes 2014 training camp, Visentin suffered an ankle injury which ended up leading to season ending surgery. Due to the nature of the surgery, Visentin did not partake in a single game during the 2014-2015 season. Following the 2014-15 season, the Coyotes elected not to give Visentin a qualifying offer, making him an unrestricted free agent. On July 8, 2015, Visentin signed a one-year contract with the Rockford IceHogs, the AHL affiliate of the Chicago Blackhawks. In the 2015–16 season, Visentin appeared in only 13 games with 4 wins, before his season was cut short due another ankle injury which required season ending surgery. As a free agent in the off-season, Visentin remained in the AHL despite leaving the IceHogs, agreeing to a one-year deal with the Milwaukee Admirals, an affiliate to the Nashville Predators on August 1, 2016. The deal reacquainted Visentin and Ben Vanderklok. He appeared in just one game with the Admirals in the 2016–17 season, primarily playing in the ECHL with affiliate, the Cincinnati Cyclones, in winning 10 contests in 26 games. Visentin opted to pursue European opportunities for the 2017-2018 season, agreeing to a one-year deal with Hungarian club Alba Volán Székesfehérvár of the Erste Bank Eishockey Liga on May 17, 2017. Visentin's contract with Székesfehérvár was terminated due to an injury on October 3, 2017 after appearing in only one game. On October 2, 2018, Visentin announced his retirement from professional hockey via Twitter.
International play
Visentin's first experience with Hockey Canada resulted in a gold medal with Team Ontario at the 2009 World Under-17 Hockey Challenge. During the summer of 2010, Visentin spent time in the summer at Team Canada's summer development camp, as well as Hockey Canada's goaltender camp. Visentin was named to Canada's roster for the 2011 World Junior Championships. Olivier Roy was Canada's starting goaltender for most of the tournament, but Visentin replaced him after Canada's loss to Sweden. Visentin started in Canada's wins against Switzerland in the quarterfinals, and against the United States in the semi-finals, for which he was named Canada's Player of the Game. These performances secured his spot as Canada's starting goaltender in the gold medal game against Russia. But in the final, Visentin conceded five goals in the third period as Russia came from behind to win 5–3. After the game, Visentin struggled to explain what had happened: "There's really no words to describe it."
