Income Tax in citizen application

[Francisco000]

Hi guys, thanks for your help with these two questions:

There is a question in the application where I have to check "Required to file" and "Taxes filed". Required to file means that I was required by CRA to file it or if it was because of my income I know myself I have to file it?

As a mailing address and as second telephone number, can I use an address and telephone outside Canada?

I appreciate the orientation you could give me. Thanks!

any of the following, you're required to file income tax

If you are a (income tax wise) a resident (183 days or more), you have to file it
If you becomes a resident/non-resident, you have to file it
if you are a non-resident but you have canadian source income, you have to file it
