Before I address the question itself, I will just say that, as a daughter of Nova Scotia, I can agree that we can all be very proud of the work being done in Nova Scotia, as well as in Quebec, B.C. and around the country to advance our national shipbuilding strategy. Not only is this work important to ensure that the navy has the equipment it needs to serve Canadians. It is creating high-quality jobs and economic benefits in communities across our country.
With respect to our NATO commitments, I can say unequivocally that we have and will continue to deepen co-operation with our friends, our allies and our partners to support stability in the region. The recent deeply concerning buildup of Russian forces at the Ukrainian border underscores the importance of Canada's activities in the region.
We have extended and expanded Operation Unifier. We have committed $340 million over three years to ensure that we continue training Ukrainian soldiers. We have put forward a $120-million loan and $50 million in humanitarian aid. Those are representations of our commitment, not only to Ukraine but to democracy, peace, stability and security in the western world. This is why we have approved additional measures to continue to support Ukrainian sovereignty.
You mentioned the broader NATO alliance. I want to reiterate our commitment to Operation Reassurance as well, in the region of NATO's eastern flank. Canada leads a high-readiness, multinational battle group in Latvia comprised of approximately 1,500 soldiers, representing 10 allied nations. Canadian soldiers are serving alongside soldiers from 10 of our NATO allies. Operation Reassurance is Canada's largest military commitment, involving the deployment of land, air and sea elements. As you mentioned, we also contributed two frigates, Halifax class frigates, which set sail on January 19 to join a standing NATO maritime group in European waters. In addition, six CF-18 Hornets are also periodically deployed in support of NATO's enhanced air policing activities in Romania, with the next scheduled deployment set for fall 2022.
I do have my chief of the defence staff, Wayne Eyre, with me. He will add anything he likes, if that's permitted by the questioner at the current time.
