I am Canadian citizen living abroad. Now I am planning to move back to Canada. I don't have Non resident card or number. I did not file any tax returns for last 18 years. Please advice if I need to take any path or just move back and start living there
Just move back. Fill out the BSF forms for CBSA for the goods you are bringing with you. CBSA might have a few questions, but nothing significant. You’ll probably need to stop by Service Canada to get your SIN reactivated.
