Seems like this

>Canadian political leadership have openly stated they have no desire to join AUKUS, even though their military leadership is screaming for it.

Is directly opposed by this

>US will not allow Canada to share nuclear submarine designs until it accepts the NW Passage as an international strait, same as Malacca or Hormuz

The Straits of Hormuz and Malacca are of course irrelevant here, since the shortest (desired) routes of the Northwest Passage take it through exclusively Canadian waters rather than waters shared by two nations. Comparisons to the Bosphorus and the Dardennelles straits are more appropriate.
