"Yeah baby!" and "You can put it in the win column" were a part of his trademark calls. He announced the Flames historic 1989 Stanley Cup victory and their 1986 and 2004 Stanley Cup final appearances. His last Flames broadcast was April 13, 2014. The Saddledome's radio broadcast booth was named in his honour. Peter received the Hockey Hall of Fame's Foster Hewitt Memorial Award in 2006.

During his career, he was also the radio play-by-play announcer for six NHL All-Star Games and the 2005 International Ice Hockey Federation (IIHF) World Championship. He called one of the most exciting goals in Canadian Olympic history, as he was the radio play-by-play announcer at the 2010 Winter Olympic Games, where he described Sidney Crosby's infamous gold medal winning goal.
Flames radio colour analyst Peter Loubardias described Peter Maher as " the consummate professional. It never was about Peter Maher. It was about the game. It was about being the best radio play-by-play broadcaster he could be. You see, to Maher his audience and the craft came first. He carried himself with class and grace."
