Yes, it's a really strong point that Canada has not met its obligations in peacekeeping forces. That is a really interesting lever to pull and one that could be used to push the Government of Canada to do so and to meet this gap that's caused by distrust in the AU.
In terms of arms, there's the UAE, but there are countries like Turkey, with which Canada has a relationship that can be leveraged in bilateral and multilateral discussions. The arms piece is really important as well.
On that note, I would suggest, as I think I mentioned earlier, that Canada support a Security Council-led arms embargo, which was one of the recommendations put forth by Human Rights Watch.
