Do I need to mention my spouse and kids who live outside of Canada and are not residents of the country?

Hi everyone,

I am trying to complete my first tax return and I am a little confused.

 

I am married but my spouse is not a resident of Canada, she lives in another country and she has never been in Canada. Do I need to mention here in my tax return and do I need to state her income?

 

We also have kids. My wife has 2 children of her own who have never been in Canada and are not residents of this country. Those are considered my stepchildren.

 

We also have a son together. He is my biological child. He has never been in Canada and he is not a Canadian resident.

 

Do I need to mention children in my tax return?

 

Thanks!
