Eleven Canadian Armed Forces divers and support personnel, including a contingent from CFB Esquimalt near Victoria, are working in Latvia to clear explosives from the bottom of the Baltic Sea.
A news release from the armed forces says the mines and other explosives date back to the First and Second World wars.
The work is carried out annually and has been underway since 1997 as Estonia, Latvia and Lithuania work to ensure shipping routes, fishing areas and seabed communication lines are safer.
The team from Esquimalt is part of a multinational naval mine clearance and ordnance disposal mission that includes the three Baltic nations as well as members from 13 other NATO nations.
