Do you have to file two tax returns if you have worked in two different provinces?

In Canada, if you have worked in two different provinces during the tax year, you do not need to file two separate tax returns. You will file one federal tax return and report all your income from both provinces on that return. However, you may need to complete provincial tax forms for each province where you earned income, as each province has its own tax rates and credits. Ensure you allocate your income and any taxes paid correctly between the provinces.
