I think it is a welcome measure. I think this is an attempt by Turkey to try to make sure that the conflict does not escalate. They're exercising the provisions of the Montreux treaty, which they're the treaty holder for, so I think it is very positive.
I don't think it is going to have a significant impact on the Royal Canadian Navy's operations in support of NATO at this time. As I understand it, there's no intention for RCN units to operate in the Black Sea.
