Since his death, Diefenbaker has had several locations named in his honour, particularly in his home province of Saskatchewan, including Lake Diefenbaker, the largest lake in Southern Saskatchewan, and the Diefenbaker Bridge in Prince Albert. In 1993, Saskatoon renamed its airport the Saskatoon John G. Diefenbaker International Airport. The city of Prince Albert continues to maintain the house he resided in from 1947 to 1975 as a public museum known as Diefenbaker House; it was designated a National Historic Site in 2018.
