I've been deemed resident in Canada for 7 months (I entered date in "Enter the date you ceased to be a resident of Canada during 2017 (dd/mm)". After that I had little income in another country, which have been taxed also there and this country have tax treaty with Canada. I entered foreign income under Other Income, Deductions and Credits Line 256. I also reported it under Foreign Slip and under contact info "Income from Foreign sources, plus Canadian sourced Part XIII income, for the part of the year when you were not a resident of Canada". But now my non-refundable tax credit is adjusted based on days I spent in Canada. But my Canadian income was over 90% of world income, so I should get full tax credit.
