In 1992–93, his first professional season, he played for the Binghamton Rangers, New York's AHL affiliate, and won the Aldege "Baz" Bastien Memorial Award as the league's top goalie.

The shootout-winning goal by Peter Forsberg was depicted on a Swedish postage stamp, featuring the image of a generic goalie because Hirsch refused to allow his likeness to be used.

[2] Hirsch split goaltending duties with Kirk McLean in 1995–96 and was named to the All-Rookie Team after posting a 2.93 goals-against average, .903 save percentage and a winning 17–14–6 record.

[2] On July 2, 1999, he was waived by the Canucks[2] and for the next few seasons, would bounce around the league between the Nashville Predators, Mighty Ducks of Anaheim, Washington Capitals, and Dallas Stars.

[5] In the summer of 2015, Hirsch's son Hayden, who is a forward, attended hockey training camp with his father's old junior team, the Kamloops Blazers, but didn't make the regular season roster.

He elaborated further about his mental health challenges in his autobiography, "The Save of My Life: My Journey Out of the Dark", which was written in collaboration with Sean Patrick Conboy and published in 2022.

Hirsch also co-hosts a podcast with psychiatrist Dr. Diane McIntosh called "Blindsided", featuring athletes talking about mental health.
