During the Yugoslav Wars in the early 1990s, soldiers from PPCLI served in the United Nations Protection Force (UNPROFOR), the United Nations peacekeeping force in Croatia. In the autumn of 1992 The 3rd Battalion replaced the Royal 22nd Regiment in Sector North, stationed out of Camp Polom, near Pakrac. The 22nd had actually spent much of their six-month tour out of position. They were with General Lewis MacKenzie, securing the Sarajevo airport for UN relief shipments. It was replaced by a battle group of 875 members mostly from the 2nd Battalion PPCLI in 1993. The battle group was dispatched to the Medak Pocket in September 1993 to interpose themselves between Serb and Croatian forces. After the Croatians opened fire on the PPCLI troops, they became involved in an intense firefight. In 2002 Colonel Jim Calvin and his men were awarded the Commander-in-Chief Unit Commendation for their bravery. A battle group drawn mostly from 1st Battalion PPCLI replaced the 2nd in 1994; the 2nd Battalion also served with the stabilization force in 1997, 2000 and 2003, the 3rd Battalion in 2000, and the 1st Battalion in 2002 and 2003. B Company, 1st Battalion, deployed as part of Lord Strathcona's Horse (Royal Canadians) Battle Group to northwest Bosnia from July 1997 to January 1998. Elements of PPCLI served with Lord Strathcona's Horse during the 1917–1918 winter, and in 1999, the 1st Battalion sent a complete battle group to the Kosovo Force.
