i didn't until right now! i was looking at maps, and saw a strange "nu" on the east side of the northwest territories of canada, and then i saw a boundary line, and then i zoomed in and saw "nunavat." and then, friends, i googled.
apparently this happened in 1999! no wonder i didn't know about it! i had to learn canadian provinces and capitals way before that in school, and then i never heard about them again! i am too old to have learned about nunavut! hence, i am learning all about it on my own time, right now.
