Is the situation in the US where some cities shelter undocumented immigrants against deportation from the federal plan to remove them particular to the country?
https://en.wikipedia.org/wiki/Sanctuary_city
I see some Canadian examples on Wikipedia, but they all appear to have their status as sanctuary city established relatively recently (within this decade, if not last few years) and often it seems to be implied to be following the US example.
Looking up the definition on Wikipedia, it seems like most non-US or Canadian examples are talking about different phenomenon -- being welcoming to asylum seekers or refugees (ie. wanting to attract the immigrants to begin with, rather than having them arrive, and then protecting them later from being sent away).
The idea that a city will "hold out" against sending an undocumented immigrant back to his/her home country because the city wants to protect them, even if the country at a larger political level wants them out seems to strike me as a very American form of conflict between a lower (municipal) and higher level political division (federal).
Like the city is saying "we want you here and will protect you" vs. the country saying "we want you out!" and the fate of the illegal/undocumented immigrant hanging in the balance isn't really something I've heard of as much outside the US.
