The 164th Battalion (Halton and Dufferin), CEF, was a unit in the Canadian Expeditionary Force during the First World War.

Based in Orangeville, Ontario, the unit began recruiting in late 1915 in Halton and Dufferin Counties.

[citation needed] The 164th (Halton and Dufferin) Battalion, CEF was assigned to the 13th Brigade of the 5th Canadian Division,[1] and was based at Witley Camp.

On April 16, 1918, the remaining members of the battalion—six officers and 92 other ranks—were absorbed into the 8th Reserve Battalion.

A copy of the enlistment papers is also included in the binders holding The 164th Battalion Project.
