Which country has better retirement benefits, Britain or Canada?

If we just say that welfare individuals think that Britain's is better. But realistically speaking, there are no more people in that small piece of land in Britain. There are too many people, the government is not good at governance, and social security is not good. Think about China and India. Moreover, visas are particularly troublesome, and it is even more troublesome to apply for immigration.

Canada is big enough. There are many people in the south, but the northern region is still vast and sparsely populated. However, Canada is now slowly tightening, and the government is slowly raising the threshold for China immigrants to go there.
