History

Early history 
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 Northumberland County region of Canada West (now the Province of Ontario). On 5 October 1866, the 40th Northumberland Battalion of Infantry was authorized for service by the regimentation of six of these previously authorized independent militia rifle and infantry companies. Its Regimental Headquarters was located at Cobourg and had companies at Cobourg, Campbellford, Brighton, Cold Springs, Grafton, Colborne, Castleton and Warkworth, Ontario. North West Rebellion 
On 10 April 1885, the 40th Northumberland Battalion of Infantry mobilized a company for active service with The Midland Battalion where it served in the Alberta Column of the North West Field Force. On 24 July 1885, the company was removed from active service. Early 1900s 
On 8 May 1900, the 40th Northumberland Battalion of Infantry was redesignated as the 40th Northumberland Regiment. Great War 
On 7 November 1914, the 39th Battalion, CEF was authorized for service and on 17 June 1915, the battalion embarked for Great Britain. After its arrival in the UK, the battalion provided reinforcements to the Canadian Corps in the field. On 4 January 1917, the battalion's personnel were absorbed by the 6th Reserve Battalion, CEF. On 22 December 1915, the 139th (Northumberland) Battalion, CEF was authorized for service and on 27 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 36th Reserve Battalion, CEF to provide reinforcements to the Canadian Corps in the field. On 21 May 1917, the 139th Battalion, CEF was disbanded. 1920s-1930s 
On 15 March 1920, as a result of the Otter Commission and the following post-war reorganization of the militia, the 40th Northumberland Regiment was redesignated as The Northumberland (Ontario) 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. On 15 May 1924, the regiment was redesignated for the final time as The Northumberland Regiment. As a result of the 1936 Canadian Militia Reorganization, on 15 December 1936, The Northumberland Regiment was amalgamated with The Durham Regiment to form The Midland Regiment (Northumberland and Durham).
