The Governor General's Horse Guards is an armoured cavalry regiment in the Primary Reserve of the Canadian Army.

[2] The regiment maintains a traditional structure, with squadrons and units for deployment and active duty, training, ceremony, cadets, and administration.

It runs leadership-specific training preparing soldiers for leadership courses as Squadron Headquarters staff, troop leaders, crew commanders and instructors.

It provides soldiers for Canadian Forces missions outside of Canada, and is expected to mobilize in national emergencies in aid to the civil power.

The soldiers are trained on the military variant of the Mercedes-Benz G-Class Wagon or LUVW Command and Reconnaissance platform equipped with a 7.62 mm general-purpose machine gun (GPMG).

The TAPV is equipped with a remote weapons system (RWS) armed with a 7.62 mm GPMG and C16 grenade launcher.

Headquarters Squadron provides essential administrative and support functions to include orderly room, recruiting, quartermaster stores and transport for the regiment.

The troop is commanded by a serving officer who acts as the unit public affairs representative, and they wear the full dragoon guard uniform with its accoutrements on horseback.

The uniform was modified over time but remained consistent in its general colour and form with blue cloth and white facings, with silver buttons and fittings, and a shako for headgear.

The new uniform included a metal 1876 Albert Pattern helmet with a white plume, and was granted the privilege to wear augelites by all ranks in that same year.

The regiment retained the 1871 uniform pattern, but changed the facing colours to red to match that of their namesake and allied unit in Britain, The Royal Horse Guards.

The helmet remains in service with a red plume, but a forage cap was also adopted in the unit colours with guards peaks.

The mess dress worn by officers and senior non-commissioned members of the regiment includes a blue jacket with scarlet vest.

The Troop met the rebels at Gallows Hill, what is now the intersection at St Clair Ave, on Young Street assisting in the repelling of their advance on the town.

The Governor General's Body Guard for Ontario mobilized as a Squadron of 75 men and horses for active service on 10 April 1885 and served in the Alberta Column of the North West Field Force.

The Commander of the force, LtCol GT Denison III, made friends with the Chief and petitioned for his release.

Both the Governor General's Body Guard and the 9th Mississauga Horse, like most of the militia units at the time, remained in Canada to recruit and raise numbered Battalions for the Canadian Expeditionary Force.

It remained in France and Flanders on the front lines for the remainder of the war, taking part in most of the major CEF battles with distinction.

On 20 February 1945 the regiment moved with the I Canadian Corps to North-West Europe as part of OPERATION GOLDFLAKE, where it was engaged in the Netherlands and continued to fight until the end of the war.

The Regiment has augmented many Regular Force UN missions to include Korea, Egypt, Golan Heights, Cyprus and Bosnia.

The Regiment supported a number of national emergency responses with troops to include Hurricane Hazel in 1954, security posts at the Olympics in Montreal and Commonwealth Games in Edmonton in the 1970s, the Ice Storm in Ottawa in 1998, Tsunami in the Philippines 2011, and the Quebec Floods in 2014 and Ontario in 2018.

The regiment contributed an aggregate of more than 20% of its authorized strength to the various Task Forces which served in Afghanistan between 2002 and 2014 totaling 35 soldiers.

Soldiers served in a number of roles, the largest being part of the Combat Logistics Patrols at Kandahar Air Field.
