Canada

I think it's pretty rare for recent immigrants (first gen, and second gen to a lesser extent) to end up homeless in canada, since they usually are well off financially or have family that can support them. Impoverished people don't travel internationally. Most non-white non-indigenous people here have been here for only a few decades. Chinese and HK immigrants go back further, but it tracks as there are a number of chinese homeless too.

(Other ethnic groups also immigrated in past centuries but not to huge populations.)

Unlike the US, Vancouver doesn't have a large black population, and the latinx population is not huge either (I mean think about it, we have like 1 good mexican restaurant.)

I am not an expert, just hypothesising.
