Bouchard played an important role, along with Bill Nyrop, as steady defensive-defencemen to the Canadien’s offensive “superstar” trio of Robinson, Savard and Lapointe who dominated the NHL blueline in the 1970s.

[1] In his rookie year in 1970–71, Bouchard was part of the Canadiens' team that upset the powerful, record-breaking Boston Bruins in the first round and went on to win the Stanley Cup.

[2] Prior to the 1978–79 season, a failed manipulation of the waiver system by the Canadiens led Bouchard's rights to unintentionally move from Montreal to Washington.

Montreal had intended to reclaim him, but NHL President John Ziegler rejected the deal citing league bylaws which the Board of Governors refused to change.

From 1970 to 1975 Pierre was on the same team as Henri Richard, creating the unusual occurrence of a player having been teammates with both father and son in the NHL.
