Several exchange visits have taken place over the years. In 1969, officers and men of the Ontarios performed 'groundskeeping' duties on the occasion of the Welsh’s amalgamation parade at Cardiff Castle, and Capt Russell Baird represented the Ontarios at the Investiture in Caernarvon. In September 1983, a small group of Welsh officers and soldiers were on parade in Oshawa on the occasion of the Ontarios’ change of command. In July 1989, the Ontarios sent a 35-man guard to Wales for the RRW’s Tercentenary parade at Cardiff Castle. HRH Charles, Prince of Wales the longtime Colonel-in-Chief of the Welsh, inspected the Regiment. The Welsh reciprocated in 1991 by providing a guard for a parade at Iroquois Park in Whitby, Ontario to mark the Ontarios’ 125th anniversary. More recently, in September 2004, the Welsh band toured many of its War of 1812 battlefields near Niagara and encampments throughout Ontario including Kingston, Ontario. The band also visited Oshawa to perform at the Ontarios’ annual Parkwood Promenade, held at the home of Colonel R.S. McLaughlin, the unit's former patron and long-serving honorary colonel.
