[2] The regiment embarked for Halifax, Nova Scotia in July 1757 to take part in the Seven Years' War.

Having been renamed the 78th (Highland) Regiment of Foot, or Fraser's Highlanders in June 1758, it took part in the Siege of Louisbourg later that month, the Battle of the Plains of Abraham in September 1759 and the Montreal Campaign in August 1760.

[2] It was at the Battle of the Plains of Abraham that the 78th led the rest of the British forces in a charge against the retreating French.

[4] The regiment was disbanded in Quebec in December 1763,[2] with each man offered a grant of land if he stayed in Canada.

Of those who accepted the offer, more than 300 joined the 84th Royal Highland Emigrants when it was raised in 1775.
