Baltimore started his hockey career playing two seasons for the University of Alberta. He then joined the AHL's Springfield Kings. He was called up by the Los Angeles Kings for the 1974 playoffs but he did not see any ice time. In 1974, he signed with the Chicago Cougars of the WHA. He would play in the WHA until it folded. In the ensuing dispersal draft he was picked up by the Edmonton Oilers, where he played two games in the 1979–80 season. Baltimore is one of only two Yukon-raised players to participate in an NHL game, the other being Jarrett Dueling. After his hockey career was over, Baltimore became a litigation lawyer in Edmonton, Alberta, practicing at McCuaig Desrochers LLP.
