On July 7, 2025, His Majesty’s Canadian Ships Edmonton and Yellowknife set sail from Halifax, Nova Scotia, embarking on a critical NATO mission, Operation REASSURANCE, to bolster maritime security in European waters. From July to October 2025, these Kingston-class Maritime Coastal Defence Vessels will join Standing NATO Mine Countermeasures Group 1 (SNMCMG1), focusing on clearing historic sea mines and protecting vital undersea infrastructure, underscoring Canada’s commitment to NATO’s collective defense.
Equipped with advanced mine countermeasure technologies, including REMUS 100 Autonomous Underwater Vehicles and Royal Canadian Navy clearance diving teams, HMCS Edmonton and HMCS Yellowknife are well-prepared to tackle the challenges of this mission. Their deployment highlights Canada’s role as a reliable NATO ally, contributing to the alliance’s efforts to ensure safe and secure maritime environments in the Euro-Atlantic region.
Lieutenant-Commander Jason Pike, Commanding Officer of HMCS Edmonton, emphasized the significance of the mission, stating, “Our deployment on Operation REASSURANCE is an opportunity to showcase Canada’s naval expertise and dedication to global security. Working alongside our NATO Allies, we will contribute to maritime safety and security, ensuring the protection of critical undersea infrastructure and the clearance of historic ordnance.”
The mission reflects Canada’s broader commitment to NATO, particularly as the alliance ramps up defense spending to meet new targets. Prime Minister Mark Carney recently announced plans to increase Canada’s defense budget to 5% of GDP by 2035, a pledge that includes investments in critical minerals and defense infrastructure to support NATO’s goals. This deployment is a tangible demonstration of that commitment, with HMCS Edmonton and HMCS Yellowknife playing a pivotal role in advancing NATO’s maritime security objectives.
Lieutenant-Commander Kristoffer Gregory, Commanding Officer of HMCS Yellowknife, highlighted the strength of the crew, saying, “The strength of His Majesty’s Canadian Ship Yellowknife lies in its people. Our sailors bring skill, resilience, and unwavering dedication to every mission. As we join Standing NATO Mine Countermeasures Group One, I’m proud to lead a team that exemplifies the very best of the Royal Canadian Navy—professionals who stand ready to serve, support our Allies, and safeguard the seas.”
From July to October 2025, the ships will patrol European waters, employing their advanced capabilities to locate and dispose of unexploded ordnance, a critical task in maintaining safe maritime routes. This mission also aligns with Canada’s efforts to enhance its defense posture, as outlined by Chief of Defence Staff General Jennie Carignan, who recently expressed support for increased military spending to improve operational readiness and personnel support.
