Newcomer (Spouse) - Income from Foreign Sources

Hi All,

I am looking for some answers regarding my husband's situation.
Does he need to write his income earned in his home country before moving to Canada under the section mentioning What was your income from foreign sources and Canadian sourced part XIII income for the part of the year that you were not a Canadian resident? He already paid taxes on his foreign income. I am confused, because on the government's website under the newcomers guidelines (

https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/newcomers-canada-immigrants.html#whtr), it says the following: 

For the part of the tax year that you were not a resident of Canada

You have to report the following amounts:

• income from employment in Canada or from a business carried on in Canada

• taxable capital gains from disposing of taxable Canadian property

• taxable part of scholarships, bursaries, fellowships, and research grants you received from Canadian sources

His income does not apply to the above points. However, I have read in the forum some answers that says to enter the foreign income from abroad before moving to Canada, even if taxes were already paid on it, and even if it does not apply to the above.

Also, if he needs to input his income from Japan in this area, is there anything else he needs to fill out? 

Thanks for your help!
