Op REASSURANCE is currently the Canadian Armed Forces (CAF) largest overseas mission, through which the CAF contributes to NATO assurance and deterrence and defence measures in Central and Eastern Europe, and is part of the biggest reinforcement of Alliance collective defence in a generation.

Under Op REASSURANCE, the CAF currently has deploysed a Maritime Task Force, which contributes ships to the Standing NATO Maritime Groups; an Air Task Force, providing logistical support out of Prestwick; and a Land Task Force, including the NATO Multinational Battlegroupenhanced Forward Presence Latvia, for which Canada is the Framework nation.


The NATO Multinational Battlegroup Latvia will transition from the Latvian Mechanized Infantry Brigade to a Canada-led brigade, reporting directly to the Multinational Division Headquarters – North. Canada will complete the full implementation of persistently deployed Brigade capabilities to Latvia by 2026, at which point the Brigade will have up to 2 200 CAF members as part of the enhanced Forward Presence and supporting elements in Latvia.

How many people are deployed?

Approximately 1,500 Canadian Armed Forces members are deployed in support of Operation REASSURANCE, making it Canada’s largest current international military operation. 

What are they doing?


Maritime Task Force

Since 2014, the Canadian Armed Forces (CAF) have deployed a warship on a persistent rotational basis to be employed for exercises and operational tasks in the NATO Maritime Command’s areas of responsibility.

On 3 July 2023, HMCS Shawinigan and Summerside deployed as part of Operation REASSURANCE to join Standing NATO Mine Countermeasures Group 1.



NATO Multinational Battlegroup Latvia

The CAF has approximately 1,200 CAF members in Latvia under Operation REASSURANCE, which includes the NATO Multinational Battlegroup in Latvia (MNB-L), Task Force Latvia (TFL), as well as personnel at NATO’s Multinational Division-North (MND-N) Headquarters.

Based out of Camp Adazi, the battlegroup in Latvia is one of eight multinational battle groups in Eastern and Central Europe that are part of the largest reinforcement of NATO collective defence in a generation.

The CAF-led battlegroup includes artillery, mechanized infantry, combat support, combat service support, and electronic warfare components that conduct joint training to respond to an attack and demonstrate a unified front against adversaries. This Battle Group and other specialist enablers are fully integrated into the Latvian Land Forces Mechanized Infantry Brigade. This powerful, combat capable force provides a strong deterrent presence in Latvia against any adversary and is prepared to defend if necessary.

Canada, as the Framework Nation for the MNB-L, is responsible for supporting Canadian and NATO military objectives at the operational level through TFL; coordinating with Latvian military authorities; and improving the integration of Canadian personnel and assets with NATO Allies in Latvia and the wider MNB region. These efforts are further supported by NATO’s MND-N Headquarters, to which the CAF contributes a general officer as well as staff officers. MND-N supports the defence planning of Baltic nations, the coordination of regional military activities within the MNB-L forces region, and other high-level activities.

The battlegroup in Latvia comprises personnel from over one third of all NATO nations, including:

  • Albania
  • Canada
  • Czech Republic
  • Italy
  • Montenegro
  • North Macedonia 
  • Poland
  • Slovakia
  • Slovenia
  • Spain

Air Task Force - Prestwick

On September 15, 2022, Air Task Force Prestwick (ATF-P) was created to expand the tactical airlift detachment that previously supported Operation REASSURANCE.

ATF-P is the main transport hub via which the CAF sustains various operations across the world, including NATO deterrence and defence measures. In addition to its missions in support of Ukraine, ATF-P supports CAF deployments in Central and Eastern Europe (Op REASSURANCE), the Middle East (Op IMPACT), and Africa (Op PRESENCE), and supports observation flights under the Open Skies Treaty.

To ensure capacity and operational flexibility, ATF-P operates three CC-130J Hercules aircrafts and employs support personnel responsible for maintenance, cargo movements and administration. ATF-P is made up of approximately 60 Canadian Armed Forces members with further augmentation based on operational tempo.

History and context of the operation

NATO agreed upon and began to enact a series of military measures on April 16, 2014 based on the principles of defence, deterrence and de-escalation meant to reinforce NATO’s collective defence and demonstrate the strength of allied solidarity.

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