Canada adopted the FAL in 1954, the first country in the world to actually ante up and order enough rifles for meaningful troop trials.
Up to this point, FN had been making these rifles in small test lots of ones and twos, each embodying changes and improvements over its predecessor.
The Canadian order for 2,000 rifles "cast the FAL in concrete" for the first time, and at FN, from 1954 to 1958 the standard model of the FAL rifle was called the FAL 'Canada'...These excellent Canadian-built rifles were the standard arms of the Canadian military from first production in 1955 until 1984.

— The FAL Rifle
The Canadian Armed Forces, the Ontario Provincial Police and Royal Canadian Mounted Police operated several versions, the most common being the C1A1, similar to the British L1A1 (which became more or less a Commonwealth standard), the main difference being that rotating disc rear sight graduated from 200 to 600 yards and a two-piece firing pin.
Users could fold the trigger guard into the pistol grip, which allowed them to wear mitts when firing the weapon.
The Canadian rifle also has a shorter receiver cover than other Commonwealth variants to allow for refilling the magazine by charging it with stripper clips.
It was manufactured under license by the Canadian Arsenals Limited company.
Canada was the first country to use the FAL.
It served as Canada's standard battle rifle from the early 1950s to 1984, when it began to be phased out in favor of the lighter Diemaco C7, a licence-built version of the M16, with a number of features borrowed from the A1, A2 and A3 variations of the AR platform assault rifle.

The Canadians also operated a fully automatic variant, the C2A1, as a section support weapon, which was very similar to the Australian L2A1.
It was similar to the FN FAL 50.41/42, but with wooden attachments to the bipod legs that work as a handguard when the legs are folded.
The C2A1 used a tangent rear sight attached to the receiver cover with ranges from 200 to 1000 metres.
The C1 was equipped with a 20-round magazine and the C2 with a 30-round magazine, although the two were interchangeable.
Variants of the initial C1 and the product improved C1A1 were also made for the Royal Canadian Navy, which were capable of automatic fire, under the designations C1D and C1A1D. These weapons are identifiable by an A for "automatic", carved or stamped into the butt stock.
Boarding parties for domestic and international searches use the C1D.
