With Hart graduating from the WHL into the Flyers' professional ranks before the 2018–19 WHL season, Wolf became the Silvertips' starter. He responded in fine form, posting the highest save percentage of any goaltender in the Canadian Hockey League (min. 15 GP) and amassing a 41–15–2 record. Ranked 12th by the league's Central Scouting Bureau among North American goaltenders eligible for the 2019 NHL Entry Draft, Wolf became the 22nd and final goaltender taken when the Calgary Flames selected him in the seventh round, 214th overall.
