What's the difference between Canadian green card and nationality?

1? Canada's green card represents Canada's permanent residency (to be precise, Canada does not have a green card. Canada has a maple leaf card, which is a travel document issued to permanent residents of Canada); Canadian citizenship represents Canadian citizenship.

2? Canadian permanent residents are foreigners, and only when they apply for Canadian citizenship will they become Canadian citizens.

3? Canadian permanent residents have no right to vote and stand for election in Canada.

4? Canadian permanent residents must fulfill the obligation to live in Canada (for two years every five years).
