Of course. But it might mean that the 77% of the population that is born in Canada is more accustomed/acclimatized to immigrants. They are not a weird/rare thing, and so they are accepted/liked by a bulk of the population.

Yes, that's my personal experience. Immigrants are more xenophobic than those born in Canada.

I’ve heard before immigrants take quite negative stances on “illegal”/“undocumented”/“irregular” immigration, saying “I had to jump through all these hoops to come here, I have no sympathy for people who break the rules instead”. Is that xenophobia?

Years ago, I went on a business trip to the US, and while there an Indian-American colleague said some very Islamophobic things to me. I guess he probably brought some of that with him from India, although certainly there would have been things in the US to reinforce it. He was a 9/11 survivor and this was only a few years later, so that was likely a factor too. There is some obvious overlap between Islamophobia and xenophobia - although not all Muslims have an immigrant background (converts), and there are billions of non-Muslim foreigners
