4 Intelligence Company (4 Int Coy), in French and officially 4ième Compagnie du renseignement (4e Cie de rens), is a Canadian Forces Primary Reserve Intelligence Branch unit headquartered in Montreal,[1] with a platoon at Valcartier Garrison near Quebec City.

[3] The unit draws its historical lineage from the 4th Troop of Volunteer Cavalry of Montreal (or Guides) that took part in the actions to repel Fenian raiders attempting to invade Canada in 1866.

[4] Members of the unit deploy on domestic[5] and foreign[6][7] operations, and are primarily responsible for tactical, or combat intelligence.

[18] This is the only instance of a Primary Reserve Intelligence Branch unit being mobilized in Canadian military history.

In the badge the traditional colours and compass rose of the Canadian Forces Intelligence Branch are placed within a bordure of fleurs-de-lis, indicating that the unit is based in Quebec.

[20] 4 Intelligence Company acquired a Russian T-72 tank on February 2, 1996 for full-scale identification training.
