Thank you for choosing TurboTax. For your question:
1. Yes, you need file tax for your spouse for both 2019 and 2020 tax return if this is the first time you are filing your tax return in Canada but it should be separated tax package for 2019 and 2020 tax return . If this is not the first time you file your tax return in Canada, you should only file your tax return for your spouse in 2020 tax return as a factual resident in Canada, it is same tax package as filing the tax return for resident in Canada.
2. Your spouse residency status in 2019 and 2020 for tax purposes is factual resident - temporarily outside in Canada. And you should file tax return for your spouse as a factual resident in Canada (same as resident in Canada).
3. However, the information which you gave us is not very specific. We would like suggest that you can go to the CRA and contact the international tax to verify your spouse's tax information.
For more information, you can verify and get on CRA website about Factual Residents - Temporarily outside in Canada.
If you have any further questions, please feel free to ask us anytime. Thank you for choosing TurboTax Community.
