"Nipigon" underwent another refit, this time at Port Weller, Ontario beginning on 30 August 1988 and lasting to 16 February 1990. In August 1991, the destroyer was deployed to STANAVFORLANT, the standing NATO fleet. In May 1993, "Nipigon" took part in commemorative events remembering the Battle of the Atlantic in Liverpool and off the Welsh coast. In 1995, "Nipigon" was deployed into the Atlantic as a guard ship during the Turbot War. In June 1995, the destroyer intercepted the Spanish fishing vessel "Patricia Nores", and boarded her just outside Canada's exclusive economic zone. Eleven tonnes of unrecorded turbot catch was found aboard "Patricia Nores" in a secret compartment.
