By your phone number?
Neither your nationality nor your residence status (permanent, temporary, so-called “illegal”) are taken into account. The only thing that counts is whether you are based in the EU.
Once I move back into the EU, does GDPR apply to data that has been collected about me while I was a Canadian resident?
How does one prove residency to a company?

One doesn't. I misquoted in my previous post. The territorial scope is defined in Article 3. Para. 2 says:
“This Regulation applies to the processing of personal data of data subjects who are in the Union […]”

In case you are not familiar with reading legal texts: skip the recital. Do a search for “Article 1”, that's where the law proper starts. Art. 1 will tell you what the law is about. Check out the headings of each section, read the text of those of interest to you, refer to the definitions provided in the law itself, follow cross references.
@johnathan012 Yes, I assume that a lot of companies imply my citizenship based on my current phone number.
I’m with a German bank which assumes that I was a citizen of the United States because my Canadian phone number starts with +1. They deny me parts of their services because of this.
