These activities include the provision of military capabilities for training, exercises, demonstrations and assigned NATO tasks and demonstrate Canada’s commitment to promote security and stability in Central and Eastern Europe.


Enhanced Forward Presence Battle Group Latvia

In June 2017, the CAF deployed about 540 Canadian Army members to Latvia. They lead a NATO Battle Group, which forms the backbone of the Enhanced Forward Presence in Latvia, and provide support capabilities to this Allied force. The Enhanced Forward Presence in Latvia comprises personnel from over one third of all NATO nations, including:

  • Albania
  • Canada
  • Czech Republic
  • Iceland
  • Italy
  • Montenegro
  • Poland
  • Slovakia
  • Slovenia
  • Spain

This Battle Group and other specialist enablers work as part of the Latvian Land Forces Infantry Brigade. It is based at Camp Adazi, Latvia.

NATO has deployed four such Battle Groups to the Baltics and Poland. These Battle Groups demonstrate the strength of the NATO alliance, and aim to deter aggression, prevent conflict and protect stability in the region.

On February 22, it was announced that a battery of M777 artillery guns with forward observers, and an electronic warfare troop, consisting of approximately 155 soldiers, would also be attached to the Battle Group.

During this deployment, the CF-188 Hornet augmented the air policing capabilities of the Romanian Air Force.

This marked the sixth time that the CAF deployed an ATF to Romania on Op REASSURANCE. The first time was in 2014 in Campia Turzii, and then in Constanta, Romania, in 2017, 2018, 2019 and 2020.

On February 22, it was announced that a CP-140 Aurora long range patrol aircraft, previously assigned to operations in and around Iceland, was re-tasked under NATO command and control, and is currently operating in the Euro-Atlantic Area.

The CAF offered assets and members to NATO on April 17, 2014.
