Foreign income of non resident spouse

I need to enter the foreign income of a non resident spouse. This foreign income is earned in a country with tax treaty. The schedule 2 worksheet in Taxcycle, however, seems to be asking for taxable income. Should I enter the income as zero in schedule 2? If I do, the family income will not be correctly reflected in the GST credits. If not, where should I enter the income information in the software.

Is this a family who just immigrated to Canada in 2015?
Perhaps your client is not yet tax-resident in Canada?
(For partial year residents (new immigrants) residency changes in the year, so you would need to carefully adjust earnings…)

Perhaps the discussion at this recent link would help?
