On 12 March 1764, Colonel Frederick Haldimand ordered, from Trois-Rivières, Quebec, the formation of a volunteer unit to aid in the defence of Canada. In response, the 1st Company, District of Montreal Militia was raised, under the command of Captain de Montizambert; the company was drawn from the traditional Militia of the Ancien Régime, and was predominantly French-speaking. This company was raised in status to a battalion in 1807, becoming the 1st Battalion, Montreal Militia under the command of Lieutenant-Colonel James McGill, founder of McGill University. Elements of the 1st Battalion fought at the Battle of Châteauguay (26 October 1813) under the command of Lieutenant-Colonel Charles de Salaberry; as a result of their conduct, the 1st Battalion was awarded a pair of Colours after recommendation by the Commander-in-Chief, Sir George Prevost, to the Prince Regent.
