Hello,
If you have earned income in Canada, you should file your taxes for the entire year or part of the tax year you’ve lived in Canada.
You do not need to file a tax return before you can begin receiving benefits and credits during your first year in Canada. However, you do need to file a tax return to continue getting benefits and credits after your first year in Canada.
