Immigration AttorneyYou will need to consult a Canadian licensed immigration lawyer regarding residency requirements in Canada. The U.S. requires that your primary residence be in the U.S. and you are also required to file and pay income taxes on worldwide income once you become conditional permanent resident. If you intend to stay outside the U.S. for a period longer than one year, you must apply for a re-entry permit that will allow you to be outside the U.S. for up to two years or validity of your two-year green card (whichever is shorter). You must still maintain ties to the U.S., demonstrating it is the country of your permanent residence, such as having a home or apartment, family in the U.S., assets in the U.S., filing U.S. taxes, children registered in U.S. schools, etc.
