I agree wholeheartedly that arguably there's never been a time in our history when movement towards nuclear disarmament was more important. Unfortunately, because of COVID, the NPT review conference has had to be postponed several times. It is now set for August. Canada will be a full and constructive participant at that review conference.
On the TPNW specifically, we have some reservations about the structure of that treaty, in that there's no verification mechanism involved in it. However, we understand that it exists—that the TPNW has been formulated—because of large-scale frustration among the international community about the slow pace of disarmament. No decision has been taken at the moment as to whether Canada will send an observer to that conference, but it is under active consideration.
