Moving south does not cure a Canadian of wanderlust. A month in Portugal, a summer at the family cottage in Muskoka, a long winter trip through Southeast Asia. Living in Denver or Charlotte simply changes the departure airport.

What changes more is the paperwork behind each trip. Many Canadians living in America hold a green card rather than U.S. citizenship. That card comes with travel conditions. Long trips can also shift where you are taxed and which benefits follow you.
A green card is permission to live in the United States permanently. The key word is live. Immigration officers expect your main home to stay in the U.S. even when you are away.
Short trips rarely raise questions. Long ones can, because a long absence may suggest you have moved somewhere else. That is true even when the trip is a sabbatical you always meant to come back from.
Canadian passports make the trips feel easy, since border lines are familiar. The status question still applies at every return. Planning a multi-country trip before you fly should include the date you need to be back.
The USCIS guidance on international travel sets out the main lines. They work like a set of thresholds.
Status can be questioned on a shorter trip too. Even a trip under a year can count as abandonment. USCIS looks at whether you still meant the U.S. to be home.
A green card holder is a U.S. tax resident for the whole year, whatever the day count. You report worldwide income on a resident return, even after six months abroad. USCIS lists filing as a resident as one sign you meant to keep the U.S. as home.
Canada works differently. It taxes on residence, not citizenship, so a Canadian who has truly left is usually a non-resident. A long summer back home does not change that alone, but rebuilding ties can. Keep the cottage visits clearly temporary.
Old Canadian accounts need attention too, and trips home are a good time to review them. The CRA charges 1% per month on TFSA contributions made while you are a non-resident. An RRSP can usually stay put, since the U.S. now defers tax on its growth automatically for most holders.
Travel exposes gaps in benefits that you never notice at home. Here is how the main programs behave for a Canadian living in the U.S.
| Program | What happens when you live in the U.S. or travel |
| Canada Pension Plan | Paid wherever you live once you qualify |
| Old Age Security | Paid abroad after 20 years of Canadian residence from age 18 |
| Provincial health plan | Usually ends once you move away for good |
| Medicare | Generally does not cover care outside the U.S. |
CPP can start as early as age 60, while OAS begins at 65. Service Canada can deposit both into a U.S. bank account, so the payments travel well.
The Medicare gap matters most for retirees who travel. Anyone exploring the world after retirement should price travel medical cover before booking. The Canada-U.S. Social Security agreement can also help with the 20-year OAS test, since some U.S. periods may count.
A little preparation makes long trips calm. Officers can ask where you work, where you live and why you were away. A folder with proof of each answer turns a tense moment into a short chat. Keep these items together before each departure.

A green card does not mean staying home. It means planning trips with a return date in mind, and a calendar alert well before it. Under 6 months is simple, and over a year needs a permit in hand before you go.
Taxes and benefits follow the same logic. Keep your U.S. ties strong, avoid rebuilding Canadian ones by accident, and check what each account allows. Do that, and the U.S. stays home base for every trip you take. Recheck the rules before any trip longer than six months.
Yes. A few months away each year is normal, provided your main home stays south of the border. Keep your trips under 6 months if you plan to apply for citizenship.
No. A reentry permit protects your immigration status, not your tax position. As a green card holder, you still file a U.S. resident return on worldwide income.
NEXUS is open to citizens and permanent residents of both countries. A Canadian with a green card can usually keep using it. Update your address with the program after the move.
Usually not, once you are a non-resident of Canada. You may still owe Canadian tax on some Canadian-source income. A final departure return is filed for the year you left.
