Flying to Canada and arriving at Northern Ontario airports

How flights connect to Northern Ontario

The airports newcomers actually finish at are YQT Thunder Bay, YSB Sudbury, YAM Sault Ste. Marie, YYB North Bay, and YTS Timmins. Most international arrivals land first at Toronto Pearson (YYZ) or Montreal (YUL), then connect north on Air Canada, Porter Airlines, WestJet, or the regional carrier Bearskin Airlines. Schedules and which airline flies which city change. The three-letter code printed on your ticket is the fact that matters.

The Toronto two-airport trap (YYZ vs YTZ)

Toronto has two airports, and they are not beside each other. Toronto Pearson (YYZ) and Billy Bishop Toronto City Airport (YTZ), on the downtown island, are about 30 km apart. There is no airside shuttle. A missed connection between them means a taxi, a rideshare, and a ferry or tunnel to the island, with your bags, on the day you are also clearing the border.

Many Porter flights to Thunder Bay, Sudbury, Sault Ste. Marie, and Timmins leave from YTZ, or they connect through Ottawa (YOW). Porter also flies some of those routes from YYZ. Air Canada and WestJet flights north more often use Pearson. Before you pay, read the three letters in the airport field. If you can, book the international flight and the northern flight on one through-ticket. On a through-ticket, a late border is the airline's problem to rebook. On two separate tickets, a delay can mean you buy a new flight north.

A Canadian visa or eTA does not cover every connection

A Canadian visa or electronic travel authorization (eTA) lets you enter Canada. It does not cover a stop in another country. The United States generally has no sterile airside transit: most people connecting through a US airport clear US customs, even if they never leave the airport, and need a US visa or, if their passport qualifies, an ESTA. Some connections in the United Kingdom or the Schengen area need their own transit visa. Check that country's rules before you buy a fare that stops there.

Your first Canadian port of entry

The Canada Border Services Agency (CBSA) processes you, and prints a new study permit, work permit, or Confirmation of Permanent Residence (COPR), at your first Canadian airport. For almost everyone flying north, that is YYZ or YUL. Officers at YQT, YSB, YAM, YYB, and YTS do not print those documents on a domestic connection. If you leave the border hall without the permit in your hand, the northern airport cannot fix it.

Allow at least 4–5 hours between the time your international flight lands and the time the domestic flight is scheduled to leave. August, September, and January are the heavy months for students and new workers. Lines are longer, and a tight connection is how people miss the only flight north that day.

Documents that stay in your carry-on

Checked bags get delayed. The border officer cannot wait for them. Keep every document below in the bag you carry off the plane:

• Passport.
• IRCC Port of Entry Letter of Introduction, or your COPR if you are landing as a permanent resident.
• For students: the Designated Learning Institution Letter of Acceptance, plus your Provincial Attestation Letter (PAL). For workers: the job offer and, if your permit needs one, the LMIA.
• Proof of funds.
• Proof of health insurance.
• The address where you are going in Northern Ontario, even if it is temporary.

CBSA customs: food, baggage, and the CAD $10,000 rule

Declare all food, plant, and animal products on your CBSA declaration. If you use the ArriveCAN Advance Declaration, declare them there too, and still answer the officer honestly. The Canadian Food Inspection Agency sets the rules. Start with bringing food into Canada for personal use and the traveller page for pets, food, and plants. CBSA also publishes a food, plant, and animal overview for travellers.

Commercially packaged dried tea, roasted coffee, and spices are generally permitted when you declare them. Meat, dairy, fresh produce, soil, and raw seeds meant for planting are often restricted or banned. The exact rule depends on the country the item comes from, so check the CFIA list for your itinerary before you pack a gift of food. Declaring an item that is not allowed usually means it is taken. Hiding it can mean a penalty.

You must declare CAD $10,000 or more if you are carrying it, in any mix of cash, other currencies, and bank drafts combined. There is no tax and no fee for declaring it. CBSA's currency page explains the form. Failing to declare can result in seizure of the money.

Landing in the North and getting into town

YQT, YSB, YAM, YYB, and YTS are small terminals. You will be outside in a few minutes. From October through April, keep a warm winter jacket, a hat, gloves, and closed shoes in your carry-on and put them on before you step out. Checked luggage is the wrong place for the only coat you own.

Campus airport welcome programs

If you are an international student, register with your school's international office before you fly. Pickup and welcome programs are run by each campus, spots fill in August, September, and January, and the signup is not the same form as your admission letter. Ask the office that belongs to your school:

• Lakehead University and Confederation College — Thunder Bay
• Laurentian University, Collège Boréal, and Cambrian College — Sudbury
• Algoma University and Sault College — Sault Ste. Marie
• Nipissing University and Canadore College — North Bay
• Northern College — Timmins and its other campuses

This list is the schools that publish an international-student office. It is not a promise that a van will be waiting if you have not registered.

Taxis, Uride, and the city bus

Uride operates in Thunder Bay, Sudbury, Sault Ste. Marie, North Bay, and Timmins. At a small airport, pre-book or request the ride before you walk outside. Each airport also lists taxis and, in some cities, a shuttle. In Thunder Bay, the airport's own transportation page is flyqt.ca/transportation.

City transit is the low-cost option when it is running. In Thunder Bay, route 3 Memorial is the bus that serves the airport. Route 3J is Jumbo Gardens, not the airport bus. On many weekdays a 3J trip meets route 3 at the Waterfront Terminal and continues as 3M, which is why the two numbers get mixed up. There is no Sunday or holiday service on 3J. Fares and times change, so check Thunder Bay Transit for the day you land before you count on a bus with luggage.

Thunder Bay Lift Pass, LIFT+, and intercity buses

Lift Pass is Thunder Bay Transit’s reloadable smart card. You load a monthly pass or multi-ride fares and tap the card on the farebox. Pick up a card in person at the Transit Office, 570 Fort William Road, Monday to Friday, 8:30 a.m. to 4:30 p.m., or at City Hall, 500 Donald Street East. Adult monthly passes, 10-ride passes, and blank cards are also sold at select retailers. Youth, senior, and discount monthly passes must be activated at the Transit Office, with proof of age or eligibility.

• Register the card so a lost pass can be moved to a new one. Online: open liftpassreloads.thunderbay.ca, choose the Manage tab, and complete the registration form. The City’s steps are on Manage your Lift Pass. You can also register at the Transit Office or by phone at 807-684-3744.
• Reload on the same portal, or where the City accepts cash for a reload. The portal is for registration and reloading. It does not replace picking up the first card.
• LIFT+ is door-to-door specialized transit for residents and visitors who, because of a disability, cannot use regular Thunder Bay Transit for all or part of a trip. You have to apply. Book at 807-345-0777, up to seven days ahead. A Lift Pass works on LIFT+ vehicles. Details: LIFT+ Specialized Transit.
• Leaving the city by bus: Ontario Northland publishes schedules that include Thunder Bay–Winnipeg and Thunder Bay–Sault Ste. Marie. Kasper Bus Lines lists a Thunder Bay–Winnipeg trip with one transfer, and marks several other northern routes as not running. Check the live schedule before you count on a seat.

Once you have an address, the next practical pages are housing, your first northern winter, and free settlement services. If you will drive to Minnesota or Michigan, read crossing the US land border before you go.

Crossing the land border into the United States

Two crossings matter most for Northern Ontario weekend trips. From Thunder Bay, Highway 61 reaches the Pigeon River port and the US port at Grand Portage, Minnesota, then continues to Grand Marais, Duluth, and Minneapolis. From Sault Ste. Marie, Ontario, the International Bridge crosses to Sault Ste. Marie, Michigan. A shopping run, a weekend, or a flight out of Duluth or Minneapolis–Saint Paul is still an entry to the United States. Hours change. Check CBSA border wait times for the day you travel.

A study permit, work permit, or PR card is not a US visa

Canadian citizens enter the United States without a visa. Bring a valid Canadian passport. A regular Ontario driver's licence is not a travel document. Everyone else is assessed on the passport of their country of citizenship, not on a Canadian status document.

A permanent resident card, a study permit, and a work permit do not let you into the United States. If your passport country is not in the US Visa Waiver Program — Kenya, Nigeria, India, and the Philippines are examples — you need a valid B1/B2 visitor visa in that passport before you drive to Pigeon River or the Sault bridge. Check the current country list on travel.state.gov and cbp.gov. If your passport country is in the Visa Waiver Program, you need an approved ESTA before you present yourself at the land booth. CBP has required that ESTA for land arrivals since October 1, 2022, and you also need an electronic Form I-94.

Do not roll up to the booth to "see what they say." If the officer refuses admission, that attempt can be recorded, and a refusal can make a later visa or a later trip harder. Sort the visa or the ESTA out before you leave Thunder Bay or the Sault.

Form I-94, and what you need to re-enter Canada

Non-Canadian citizens entering by land need a Form I-94. Most Canadian citizens who are visiting or in transit do not. Apply for a provisional I-94 on i94.cbp.dhs.gov up to 7 days before you arrive so you are not standing in secondary inspection while the car behind you waits. CBP's I-94 page explains the land process. CBP charges a fee. USAGov listed US $30 after the September 30, 2025 increase. Confirm the amount on the I-94 site before you pay. A provisional I-94 is not a promise that you will be admitted.

Coming back into Canada, pack the original documents, not photos on a phone:

• Permanent residents: your PR card, plus the passport you travel on. In a private vehicle, an officer can sometimes confirm your status without the card. Do not plan on that. A commercial ride, including a bus or a flight, needs the PR card or a permanent resident travel document.
• Students and workers: your passport and the original study permit or work permit. A visa-required passport should also have a valid multi-entry temporary resident visa (TRV). A visa-exempt passport does not need an eTA to drive back across the land border. An eTA is for flying into a Canadian airport, and it must be the one linked to the passport you are carrying.

IRCC's contiguous-territory rule: if your TRV has expired, you can ask to return on that original visa when you visited only the United States or St. Pierre and Miquelon and you are still inside the stay authorized by your study permit or work permit. IRCC's student travel page and the TRV help-centre answer both say the officer decides. A side trip to any other country ends the exception. A valid multi-entry TRV is the document to hold anyway. An airline flying you back from Minneapolis or Duluth checks the visa before it boards you. The land exception is not a boarding pass.

Duty-free limits on a Duluth, Grand Portage, or Sault Michigan trip

CBSA sets the personal exemption by how long you were outside Canada. The figures below are per person, the goods have to be yours, and you cannot pool one person's exemption with another's. Official text: residents returning to Canada and alcohol and tobacco limits.

• Under 24 hours (a same-day shopping trip): CAD $0. Duty and taxes, including HST, apply from the first dollar. There is no duty-free alcohol or tobacco.
• At least 24 hours and under 48 hours: CAD $200 per person. Alcohol and tobacco are not included. If the goods are worth more than CAD $200, you lose the exemption and duty and taxes apply to the full amount, not just the portion over $200. The clock is exact: leave at 7:00 p.m. Friday and you cannot claim this exemption until 7:00 p.m. Saturday.
• 48 hours or more: CAD $800 per person. Duty and taxes apply only to the amount above CAD $800. This exemption can include the standard alcohol and tobacco amounts. Alcohol, and you must be 19 or older when you enter Ontario, is one of: up to 1.5 litres of wine, or up to 1.14 litres of liquor, or up to 8.5 litres of beer (about 24 cans of 355 ml). Stamped tobacco inside the exemption can include 200 cigarettes, 50 cigars, 200 tobacco sticks, and 200 grams of manufactured tobacco. Unstamped US cigarettes can still attract a special excise duty.

Keep every receipt, including duty-free bags. Declare all of it. For the 24-hour and 48-hour claims, the goods have to be with you in the car.

Bring your driver's licence, the Ontario insurance pink slip, and the vehicle ownership. Confirm with your insurer that the policy covers driving in the United States before you go. If the car is not registered in your name, bring a signed note from the registered owner and a copy of their licence.

Do not carry cannabis in either direction. That includes dried flower, edibles, vapes, and CBD, and it includes a medical authorization. Cannabis is legal in Ontario, and it is legal in Minnesota and Michigan, and it is still illegal to take it across this border. CBSA's rule is don't bring it in, don't take it out. US Customs and Border Protection enforces the federal ban. A small amount in the trunk can mean seizure, charges, and a finding that you are not admissible to the United States. Leave it at home. Do not mail it either.

Questions people ask before they book

Why do I need four or five hours at my first Canadian airport?

CBSA processes and prints a new study permit, work permit, or Confirmation of Permanent Residence (COPR) at your first Canadian airport, usually Toronto Pearson (YYZ) or Montreal (YUL). Staff at Thunder Bay, Sudbury, Sault Ste. Marie, North Bay, and Timmins do not print those documents. Allow at least 4–5 hours between landing and your domestic flight, especially in August, September, and January. On one through-ticket, the airline rebooks you if the border takes longer. Two separate tickets can mean buying a new flight.

What is the Toronto two-airport trap?

Toronto Pearson (YYZ) and Billy Bishop Toronto City Airport (YTZ) are about 30 km apart, with no airside link between them. Many Porter flights to Thunder Bay, Sudbury, Sault Ste. Marie, and Timmins leave from YTZ, or connect through Ottawa (YOW). Porter also flies some routes from YYZ. Air Canada and WestJet northern flights more often use YYZ. Read the three-letter code on the ticket before you pay. Schedules change.

Does a Canadian visa or eTA cover a connection in another country?

A Canadian visa or eTA covers entry to Canada only. The United States generally has no sterile airside transit, so most connecting passengers clear US customs and need a US visa or, if their passport qualifies, an ESTA. Some connections in the United Kingdom or the Schengen area need their own transit visa. Check that country's rules before you buy a ticket that stops there.

Which documents must stay in my carry-on?

Keep your passport, your IRCC Port of Entry Letter of Introduction or COPR, your school's Letter of Acceptance and Provincial Attestation Letter (or your job offer and LMIA), proof of funds, health insurance, and your destination address in your carry-on. Do not pack them in checked luggage. If the bag is delayed, the border officer cannot print your permit.

What food and cash do I have to declare?

Declare every food, plant, and animal product on your CBSA declaration or ArriveCAN Advance Declaration. Commercially packaged dried tea, roasted coffee, and spices are generally allowed when you declare them. Meat, dairy, fresh produce, soil, and raw seeds for planting are often restricted or prohibited, and the rule depends on the country they come from. You must also declare CAD $10,000 or more, counting every currency and bank draft together. Declaring that money is free. Failing to declare it can mean the money is seized.

How do I get from a Northern Ontario airport into town in winter?

From October through April, put a warm jacket, hat, gloves, and closed shoes in your carry-on before you leave the terminal. Students should register with their school's international office for airport welcome or pickup before they fly. Uride operates in Thunder Bay, Sudbury, Sault Ste. Marie, North Bay, and Timmins. Airport taxis and shuttles are listed by each airport. In Thunder Bay, Transit route 3 Memorial serves the airport. Route 3J is Jumbo Gardens and is not the airport bus. Check the city schedule before you rely on a bus.

Can a study permit, work permit, or PR card get me into the United States?

A Canadian passport is what lets you enter the United States without a visa. A permanent resident card, study permit, or work permit does not. You are assessed on the passport you present. If that country is not in the US Visa Waiver Program, you need a valid B1/B2 visitor visa in that passport before you drive to Pigeon River or the Sault Ste. Marie International Bridge. If it is in the Visa Waiver Program, you need an approved ESTA before you reach the booth, plus a Form I-94. Do not drive up to ask. A refusal of admission can be recorded and can affect later trips.

What is Form I-94, and what do I need to get back into Canada?

Non-Canadian citizens entering the United States by land need a Form I-94. Apply for a provisional I-94 at i94.cbp.dhs.gov up to 7 days ahead so you are not waiting inside secondary inspection. It does not guarantee entry, and CBP charges a fee. To re-enter Canada, bring your passport. Permanent residents should bring their PR card. Students and workers should bring the original study or work permit. Visa-required travellers should also carry a valid multi-entry temporary resident visa. IRCC lets you ask to return on an expired TRV if you visited only the United States or St. Pierre and Miquelon and you are still within your authorized stay, but a valid multi-entry TRV is the safer document, especially if you fly back.

What can I bring back from a same-day trip to Duluth or Sault, Michigan?

If you were outside Canada for less than 24 hours, your personal exemption is CAD $0. Duty and taxes apply from the first dollar, and there is no alcohol or tobacco exemption. After at least 24 hours and under 48 hours, the exemption is CAD $200 per person. If your goods are worth more than CAD $200, duty and taxes apply to the full amount, and alcohol and tobacco are not included. After 48 hours or more, the exemption is CAD $800 per person. Duty and taxes apply only to the amount above CAD $800, and the usual alcohol and tobacco limits can be included. Keep every receipt. Declare everything. Never carry cannabis, including CBD, in either direction.
