The Canadian Armed Forces is a playable faction that appears in Call of Duty 3, and Call of Duty: Roads to Victory during World War II. They also make a minor appearance in Call of Duty: Modern Warfare 2 and Call of Duty: Modern Warfare 3 as Task Force 141 members.

In-Game
In Call of Duty 3, there is a campaign in which the player takes control of Private Cole.

Also In Call of Duty: Modern Warfare 2, there are Canadian NPCs in Task Force 141 that support the player during the missions "Takedown", "The Hornet's Nest", "The Gulag", and "Loose Ends". A few Canadian Task Force 141 operatives can be seen in Persona Non Grata, holding off Makarov's forces to let Price and Soap escape. They are also seen in Return to Sender, supporting Loyalist forces and other Task Force 141 operatives.

Canadian Missions
In the entire Call of Duty series, the Canadians are one of the least played factions. There are only three Canadian missions in Call of Duty 3, those three being "Falaise Road", "Laison River" and "The Corridor of Death". There is no word on whether or not there will be another Call of Duty game that will feature a Canadian campaign.

Achievements
There is one achievement for fighting in the war as a Canadian Highlander in Call of Duty.
