Is Nunavut a Canadian Puerto Rico?

[beesley]

They're both small parts of a larger country where a majority of people speak a minority language.

Yes, and they're also overlooked and maltreated by the country, but that's where the similarities end. Puerto Rico is also in a far better position to change that given the unique ethnic group + larger population, plus support from people outside of it, whereas Nunavut has a low population and low wealth, which means low power.
