Unless you're advocating that we should encourage the United States to bring nuclear weapons back and deploy them on Canadian soil, I don't see that there's a need for a discussion here. We are free of nuclear weapons. Pierre Trudeau decided that we would be. We've kept that position for decades now.
Ms. Mason is talking about finding diplomatic opportunities to help this effort to de-nuclearize the world, which many people and many countries subscribe to, and I'm just identifying that this is one of many options Canada could consider.
But to come back to it, the most important is the nuclear prohibition treaty that was just adopted. Canada could sign and ratify that, and stay in NATO. I fail to understand why we weren't at that negotiating conference, why we didn't sign, and why we aren't considering ratification at present. It's a mystery to me, because it's inconsistent. This current stance is inconsistent with decades of Canadian diplomatic history.
