The North Pole is not ... repeat NOT ... Canadian territory. If you're so brilliant, look at a map. Two questions:
1/...Is there any land within 12 miles?
2/...Do you even know where the North Pole is?
Northwest Passage? That can be argued ... and claimed as Canadian water.
1/...Change the 12 miles to 200 and you'd be a touch closer to being correct
The Northwest Passage is and has been for the last 140 yrs, Canadian waters. There have been a few weak and lame objections from Russia, USA and Denmark), but htey are pretty much discounted as political posturing. The real issue is the mass beyond Canada's 200 mile inclusion zone (i.e. Alpha Ridge and Lomonosov Ridge) and how far they extend into Canadian waters
