With the passing of the Militia Act of 1855, the first of a number of newly raised independent militia companies were established in and around the Durham County region of Canada West (now the Province of Ontario).

On 16 November 1866, the 46th East Durham Battalion of Infantry was authorized for service by the regimentation of five of these previously authorized independent militia rifle, infantry and artillery companies. Its regimental headquarters was located at Port Hope and had companies at Port Hope, Millbrook, Springville, Lifford and Janetville, Ontario.[1]

On 10 April 1885, the 46th East Durham Battalion of Infantry mobilized two companies for active service with The Midland Battalion, which served in the Alberta Column of the North West Field Force. On 24 July 1885, the battalion was removed from active service.[2]

During the South African War, the 46th Durham Battalion contributed volunteers for the Canadian contingents serving overseas. One member, Captain William Peter Keith Milligan, who had resigned his officer's commission to serve overseas, was killed in action while serving with the 2nd Canadian Mounted Rifles.[4]

On 8 May 1900, the 46th Durham Battalion of Infantry was redesignated as the 46th Durham Regiment.[1][7]

On 22 December 1915, the 136th (Durham) Battalion, CEF was authorized for service, and on 25 September 1916, the battalion embarked for Great Britain. After its arrival in the UK, on 6 October 1916, the battalion's personnel were absorbed by the 39th Reserve Battalion to provide reinforcements to the Canadian Corps in the field. On 22 May 1917, the 136th Battalion was disbanded.[2]

On 15 March 1920, as a result of the Otter Commission and the following post-war reorganization of the militia, the 46th Durham Regiment was redesignated as The Durham Regiment and was reorganized with two battalions (one of them a paper-only reserve battalion) to perpetuate the assigned war-raised battalions of the Canadian Expeditionary Force.[1][3][8]

As a result of the 1936 Canadian Militia reorganization, on 15 December 1936, The Durham Regiment was amalgamated with The Northumberland Regiment to form The Midland Regiment (Northumberland and Durham).[9][10]
