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 earningsā€¦)

Perhaps the discussion at this recent link would help?
