This was reported by the General Staff of the Ukrainian Armed Forces on Facebook.
"As Russia's war rages on, Ukrainian soldiers and civilians are facing an explosive threat on the battlefield. A troop of Canadian Combat Engineers have been helping Ukraine mitigate this threat as part of Operation UNIFIER. Lieutenant Jacques Pecora is in Poland and talks about how his team of sappers are teaching Ukrainian soldiers many of the skills they need to survive and thrive," the ministry said.
The General Staff noted that the Canadian military arrived in Poland to use their experience, train the Ukrainian Armed Forces and ensure their operational readiness.
On April 21, Ottawa announced a new USD 29 million aid package to Kyiv, which will include ammunition and sniper rifles, among other things.
