Canada replaced its British 5.5-inch medium guns in 1951 with American-designed 155-mm howitzers. Sorel Industries in Québec built 209 guns for Canadian and NATO use. It remained in service until the self-propelled M109 replaced it in 1968.
The 155-mm C1 featured a split-trail carriage, a hydro-pneumatic recoil system, and a Welin screw breech. Crews loaded separate ammunition and used variable charges to adjust range and trajectory, giving flexibility in supporting different combat situations.
Canadian units deployed the C1 in exercises across Canada and Europe. Notably, 2 RCHA operated the C1 in Germany from 1965 to 1968, contributing to Western European security during the Cold War.
