I suggest a quick quiz, Married to a nonresident alien, to determine the best action for you.
A US citizen married to a nonresident alien can file a joint return. You would include all income and also file a credit for tax paid to Canada on the income.
Your filing status is determined by your marital status on Dec 31.
