The 91st Battalion was authorized on 22 December 1915 and embarked for Britain on 29 June 1916, where its personnel were absorbed by the 12th, 35th, 36th, 37th, 38th and 39th Reserve Battalions on 15 July 1916 to provide reinforcements for the Canadian Corps in the field.
[1] The 91st Battalion recruited in Elgin County and was mobilized at St. Thomas, Ontario.
The colours were inherited by the perpetuating unit (the Elgin Regiment) and were laid up in Trinity Anglican Church in St. Thomas in 1935.
When the church was deconsecrated in 2020, the colours were removed for relocation, but they deteriorated rapidly and could not be laid up again.
