In Canada, your tax obligations are based on residency, so if you are a non-resident who doesn’t reside in Canada, you likely don’t need to file a return. However, it may be best to confirm this with the Canada Revenue Agency (CRA). If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
