 The Regular Force regiment of The Fort Garry Horse and the 4th Regiment Royal Canadian Horse Artillery were reduced to nil strength and placed on the Supplementary Order of battle on 16 June 1970.In October 1970, during the October Crisis, the army was called out as an aid to civil power with the Royal 22e Régiment being deployed to guard government buildings in Montreal on 15 October 1970.The deployment was not popular with the senior leaders of the Canadian Forces, who feared correctly that Trudeau would use the October Crisis as a reason for his "Priority One" of internal security.
