One of four infantry regiments in British Columbia, the Canadian Scottish is the largest reserve unit in Western Canada.

The unit also trains to meet the realities of the "Three Block War" – warfighting, peacekeeping, and humanitarian support.

As of 2012, all members of the regiment who were serving on combat operations with the Canadian Expeditionary Force in Afghanistan have returned home.

Members of The Canadian Scottish Regiment have also been involved in peacekeeping missions; notably in Egypt, Golan Heights, Cyprus, Croatia, Bosnia, and Sierra Leone.

The desire was to not perpetuate specific regimental identities and so the new battalion was simply referred to as "Canadian Scottish".

Since its early beginnings, the battalion had a high standard of conduct on the battlefield and was commanded by outstanding leaders.

One such was Lieutenant General Sir Arthur Currie who rose to command the Canadian Corps during the First World War.

Currie was a master tactician whose skills led the Canadians to victory at the Vimy Ridge, the Amiens, and the intense last Hundred Days campaign which ended the Great War.

Private William Milne single-handedly attacked and destroyed two enemy machine gun nests at Vimy Ridge on 9 April 1917 and was killed the same day.

Lance Corporal William Henry Metcalf and Lieutenant Colonel Cyrus Peck MP, won their VC's on the same day: 2 September 1918 during the Canadian Corps capture of the Drocourt-Quéant Line.

Piper James Richardson who was just 18 years old when he enlisted, and was killed on October 8, 1916, during the Battle of the Somme shortly after having played his company through No Man's Land.

The pipes are on display in the Canadian Scottish Regimental Museum located in the Bay Street armoury.

The 1st Battalion was mobilized for overseas service in 1940 and trained in Debert, Nova Scotia, until August 1941, from where it moved to the United Kingdom as part of the 3rd Canadian Infantry Division.

The battalion proceeded to advance a total of six miles inland – farther than any other assault brigade of the British Second Army that day.

It provided reinforcements for the Canadian Corps in the field until 18 July 1916, when its personnel were absorbed by the 30th Reserve Battalion, CEF.

On 31 December 1954, it was amalgamated with The Canadian Scottish Regiment (Princess Mary's) and the 62nd Anti-Tank Battery, RCA.

Built between 1912 and 1915, it reflects the period after the Second Boer War when over 100 drill halls and armouries were erected across Canada.

The artifacts assist military historians and serve as a training aid to teach regimental history.

The Freedom of the City was exercised by the Canadian Scottish Regiment (Princess Mary's) in Victoria, British Columbia on June 6, 1964, and in 2012.

2308 RCACC, once located in Port Alberni, disbanded at some point between 2017 (when it was last mentioned in Regional Routine Orders)[17] and 2023.
