Hello! I worked in Quebec January to April but moved out to another province where I was by December 31st. do I have to file income tax return with QC and CRA too?

I would recommend contacting Revenu Québec, as even if you weren't a resident of Québec on Dec. 31st, you might still have to file a Québec return.

 

To call them from Outside Quebec (Elsewhere in Canada or the United States): 1 800 267-6299 (toll-free)
