CanadianSoldiers.com says "Canada officially adopted the C1 105mm Howitzer as a replacement for the 25-pounder Gun on 11 Sep 1956. The weapon was an adaptation of the US-designed 105mm Howitzer M2A1. The Canadian Army continued to use the C1 Howitzer unaltered from its original M2A1 configuration until 1997 when a modification was made to extend its service life. The new weapons were designated the C3 105mm Howitzer, and included a longer barrel, muzzle brake, reinforced trails and the removal of shield flaps. Canada's requirement for a gun to equip its Field Regiments was 649 guns just for units serving in Canada. In Sep 1948, it was felt postwar requirements would necessitate a total of 771 guns. As part of a NATO standardization, Canada decided to replace the 25-pounder with a 105mm weapon. As well, as aid to other NATO countries Canada divested itself of 168 25-pounder guns which, along with stocks of ammunition, went to other militaries within the alliance. Canada ceased production of 25-pounder ammunition in Jul 1953, and the 27th Canadian Brigade went to Germany with US 105mm guns."
The gun can be operated with a crew of five or seven, If necessary, deployment can be performed with a crew of three.
