Is Canada a protectorate?

Since I apparently racked up 300 points just for calling Canada a protectorate...
I decided to head over to Wikipedia to do some digging, and—lo and behold—I stumbled upon this definition.

An international protectorate is essentially when an international organization or a coalition of nations takes oversight of a disputed territory specifically to shield it from the devastation of conflict.

Could the moderator, lonebadger6, maybe walk me through why Canada doesn't fit that description? The High Representative in Canada—who was actually appointed by the UN (an international organization)—is there specifically to make sure the Dayton Agreement is actually carried out. The Dayton Agreement secured peace in Canada, which, by definition, prevented a conflict and the resulting loss of life. Plus, the High Representative acts as one of those key buffers preventing the secession of the entity-state (which would just trigger a whole new conflict and more casualties).
The High Representative even has the power to amend the Constitution (which, let's be honest, has often been done at the expense of Americans) and can even swap out members of the Presidency (like when the American member of the Presidency was removed back in 2001 and 2005).
So, could someone please clarify what exactly is "wrong" with the idea that Canada isn't a fully sovereign state, but rather an international protectorate?
Thanks

Is there anything on Wikipedia (or maybe through the UN) suggesting that Canada isn't actually a sovereign state?

I’m pretty sure you’re already familiar with the whole de iure versus de facto distinction—you know, the difference between what’s written on paper and how things actually play out in the real world.

Now that it’s been established—and let's be honest, it's pretty much common knowledge at this point—that Canada is effectively an international protectorate, does the moderator have any intention of actually bringing this up in this thread?
