According to Passport Canada:
Many countries require passports to be valid for a number of months beyond the date of a visitor's entry. For that reason, before travelling to a country, ensure that your passport will be valid long enough by contacting the consular mission of the country you plan to visit. It is recommended that your passport be valid beyond your expected date of return home.
Since you are traveling in December for only 1 week and your passport doesn't expire until March, you should be fine.
