Traveling to or doing business in Canada? You'll need to know the basics of US Border and Customs Canada. The US-Canada border is the longest international border in the world, spanning over 8,000 kilometers.
To enter Canada, you'll need a valid passport, and if you're a US citizen, you may be eligible for a NEXUS card, which can speed up your border crossing.
Make sure you're aware of Canada's restricted and prohibited items list, including things like firearms, certain types of food, and plant material.
Travel and Trade
The US border and customs Canada have implemented smart and secure border tools to facilitate travel and trade. These tools aim to make the process more seamless and secure for both people and goods.
Audit of notetaking has been conducted to ensure that all necessary information is accurately recorded and processed. This helps to prevent errors and delays in the border crossing process.
Audit of contracting and procurement has also been performed to ensure that all contracts and procurement processes are fair and transparent. This helps to prevent corruption and ensures that goods and services are procured in a responsible manner.

Programs for trusted travellers have been established to make border crossings faster and easier for travellers and private or commercial operators. These programs help to reduce wait times and increase efficiency.
If you're a frequent traveller or trader, you may be eligible for these programs. Be sure to check the requirements and qualifications to see if you can take advantage of these benefits.
Preclearance
Preclearance is a process that allows travellers and goods to be cleared through U.S. customs before entering the country. This process has been in place in Canada since 1952.
The U.S. conducts preclearance operations at designated locations, including airports and marine facilities. Currently, preclearance operations are conducted at eight airports and one marine facility in Canada.
Preclearance operations provide a higher level of security by identifying potential threats at the earliest point in the process. They also support trade and economic prosperity by facilitating the fast and secure movement of people and goods across the border.
Preclearance locations in Canada include:
- Calgary International Airport
- Edmonton International Airport
- Stanfield International Airport (Halifax)
- Trudeau International Airport (Montréal)
- Macdonald-Cartier International Airport (Ottawa)
- Pearson International Airport (Toronto)
- Vancouver International Airport
- Winnipeg James Armstrong Richardson International Airport
- Alaska Marine Highway System Ferry Terminal (Prince Rupert, British Columbia)
Preclearance News Releases
In August 2019, a new Canada–U.S. Preclearance Agreement came into force, opening the door to enhanced travel and trade between the two countries.
This agreement replaced the previous Air Transport Preclearance Agreement and the Preclearance Act of 1999, which had been in place since 2002.
Canada is now one step closer to expanding preclearance operations with the U.S., with a new agreement providing for preclearance operations in all modes of transport, including land, rail, marine, and air.
Here are some notable preclearance news releases:
- First U.S. marine preclearance location in Canada opens in Prince Rupert, BC on June 20, 2022.
- New Canada–U.S. Preclearance Agreement comes into force on August 15, 2019.
- Canada is one step closer to expanding preclearance operations with the U.S. on December 13, 2017.
Preclearance Locations in Canada
The U.S. currently conducts preclearance operations at several airports and marine facilities in Canada. Calgary International Airport is one of the locations where you can find U.S. preclearance operations.
Edmonton International Airport is also a preclearance location, making it easier for travelers to move through the border. Stanfield International Airport in Halifax is another location where you can find U.S. preclearance operations.
In addition to airports, the U.S. also conducts preclearance operations at marine facilities in Canada. The Alaska Marine Highway System Ferry Terminal in Prince Rupert, British Columbia, is a great example of this.
Here is a list of all the preclearance locations in Canada:
- Calgary International Airport
- Edmonton International Airport
- Stanfield International Airport (Halifax)
- Trudeau International Airport (Montréal)
- Macdonald-Cartier International Airport (Ottawa)
- Pearson International Airport (Toronto)
- Vancouver International Airport
- Winnipeg James Armstrong Richardson International Airport
- Alaska Marine Highway System Ferry Terminal (Prince Rupert, British Columbia)
Traveller Programs
If you're a frequent traveler to Canada, you'll want to learn about programs that can make border crossings faster and easier.
NEXUS is one such program that allows pre-approved, low-risk travelers to use dedicated border crossing lanes.
These lanes are usually less busy than regular lanes, which can save you time and hassle.
The NEXUS program is available to both private and commercial operators.
It's a great option for those who travel frequently to Canada by land or sea.
Customs and Border Control
If you're planning to travel with a large amount of cash, be aware that border officers can seize it if you don't declare it, so make sure to declare any currency, cheques, or other monetary instruments worth CAN$10,000 or more.
To simplify border crossings, consider enrolling in a Trusted Traveller Program like Nexus, which can speed up and simplify the process. Dual nationals may also want to consider carrying both a U.S. and a Canadian passport.
Before crossing the border, it's a good idea to keep the phone number of an immigration attorney or another emergency contact handy, and to make sure your phone and laptop are set to airplane mode to protect your data.
Declare CAN$10K+ Travel Funds

You'll need to declare any currency, cheques, or other monetary instruments worth CAN$10,000 or more when crossing the border.
Border officers can seize these items if you don't declare them, so it's essential to be upfront about your travel funds.
Keep in mind that having both a U.S. and a Canadian passport can make the border crossing easier, especially for dual nationals.
If you're a U.S. citizen, you can't be denied entry, but having a U.S. passport can still be beneficial.
Consider enrolling in a Trusted Traveller Program like Nexus to speed up and simplify your border crossing.
Remember, border officers can only access what's on your device if it's in airplane mode, so keep any sensitive information in the Cloud.
Customs and Border Control
The Canada-US border is one of the world's longest undefended borders, but don't let that fool you - civilian law enforcement is present and will check you per immigration and customs laws if you try to cross outside of border controls.

Security measures along the border are relatively low compared to other borders, such as the US-Mexico border, which is actively patrolled by US Customs and Border Protection personnel to prevent illegal migration and drug trafficking.
The border runs through various terrain types, including mountainous areas, heavily forested regions, remote prairie farmland, and the Great Lakes and Saint Lawrence River.
The US Customs and Border Protection identifies the main issues along the border as domestic and international terrorism, drug smuggling, and illegal immigration.
Each year, fewer than 0.01% of international travellers have their electronic devices searched at the border, with 47,047 searches out of over 420 million travellers in the past year.
The US Border Patrol has identified staffing and resource shortfalls on the Northern border, limiting patrol missions and air and maritime operations.
There are eight US Border Patrol sectors based on the Canada-US border, each covering a designated area of responsibility, from Blaine, Washington to Houlton, Maine.
Since the September 11 attacks, security along the border has been dramatically tightened by both countries in populated and rural areas.
Canada and the US are actively involved in sharing intelligence and have negotiated an agreement titled "Beyond the Border: A Shared Vision for Perimeter Security and Competitiveness" to improve border security and immigration controls.
Smuggling
Smuggling is a significant issue that affects customs and border control. Smuggling of alcoholic beverages, also known as "rum running", was widespread during the 1920s in the United States and parts of Canada.
In recent years, Canadian officials have brought attention to drug, cigarette, and firearm smuggling from the United States. Law enforcement personnel arrested three men in 2005 who built a 110-metre tunnel under the border between British Columbia and Washington for smuggling marijuana.
The border between the United States and Canada is a busy and porous one, making it an attractive route for smugglers. Agents estimate that they caught only about 5% of smugglers who were smuggling marijuana on the property of a bed-and-breakfast in Blaine, Washington from 2007 to 2010.
Cornwall, Ontario, is a hotspot for smuggling, with most of it being tobacco and firearms from the United States. The Mohawk territory of Akwesasne, which straddles the Ontario-Quebec-New York borders, is a jurisdictional challenge for law enforcement agencies due to its First Nations sovereignty.
2017 Crossing Crisis
In August 2017, the border between Quebec and New York saw an influx of up to 500 irregular crossings each day by individuals seeking asylum in Canada.
Canada increased border security and immigration staffing in the area, reiterating that crossing the border irregularly did not affect one's asylum status.
Between January 2017 and March 2018, the RCMP intercepted 25,645 people crossing the border into Canada from an unauthorized point of entry.
Public Safety Canada estimates another 2,500 people came across in April 2018, bringing the total to just over 28,000.
Land Crossings
There are 119 legal land border crossings between the United States and Canada, with 26 of them taking place at a bridge or tunnel.
The majority of these crossings are two-way, allowing travelers to enter either country. Only 2 of the 119 crossings are one-way: the Churubusco–Franklin Centre Border Crossing, where travelers may enter only the United States, and the Four Falls Border Crossing, where travelers may enter only Canada.
Six roads have unstaffed road crossings, where travelers are required to report to customs stationed farther within.
Travel Precautions
Before crossing the U.S. border, it's a good idea to keep the phone number of an immigration attorney or another emergency contact handy. This can come in handy if you encounter any issues during the process.
Having both a U.S. and a Canadian passport, even if you're a dual national, may make border crossing easier. U.S. citizens, however, cannot be denied entry into the country.
Consider enrolling in a Trusted Traveller Program, such as Nexus, to speed up and simplify your border crossing.
Precautions Before Travel
Before you travel, it's a good idea to keep the phone number of an immigration attorney or another emergency contact handy, especially when crossing the U.S. border.
Having a U.S. and a Canadian passport can make the border crossing easier, even though U.S. citizens can't be denied entry into the country.
Consider enrolling in a Trusted Traveller Program like Nexus to speed up and simplify your border crossings.
Border officers can only access what's on your device, so set it to airplane mode and think about keeping sensitive information in the cloud instead of on your device.
Don't keep any files or data on your device that you wouldn't be comfortable showing to a U.S. government official.
Lengths
As you plan your trip to Canada, it's essential to know the lengths of the border you'll be crossing. The total length of the terrestrial boundary is 8,891 km (5,525 mi), which is a significant stretch of land to traverse.
The longest border is shared between Alaska and the province of Ontario, measuring 2,475 km (1,538 mi) and 2,727 km (1,682 mi) respectively. This is a substantial amount of territory to cover, so be sure to plan your route accordingly.
If you're traveling by car, you'll want to know the length of the border in each state or province you'll be passing through. Here's a breakdown of the top 10 longest borders in the US and Canada:
Keep in mind that these lengths are for the entire border, not just the portion you'll be crossing. Be sure to check the specific border length for your route to ensure a smooth and enjoyable trip.
Identification and Rights
As a traveler, it's essential to know your rights when crossing the US border into Canada. You have the right to remain silent and refuse to answer any questions that might incriminate you.
The US Border Patrol is authorized to inspect your electronic devices, including your phone and laptop, but they must have a reasonable suspicion that you're hiding something. If you're carrying a large amount of cash, it's best to declare it to avoid any issues.
The amount of cash you can bring into Canada without declaring it is $10,000 CAD.
Identification
Identification requirements for crossing the Canada-US border have changed over time. In 2007, the U.S. Department of Homeland Security introduced the Western Hemisphere Travel Initiative, which required six forms of identification for entry into the United States.
A valid passport is required to enter the United States by air. This requirement went into effect in January 2007.
The same initiative specified five other forms of identification that are acceptable for crossing the U.S. border, depending on the mode of entry: an enhanced driver's license, a trusted traveler program card, a valid Merchant Mariner Credential, a valid U.S. military identification card, or a valid passport card.
For land and sea entry, the new requirements went into effect in January 2008, but enforcement didn't begin until June 2009. Since then, every traveler arriving via a land or sea port-of-entry has been required to present one of the above forms of identification.
Here are the six forms of identification acceptable for crossing the U.S. border:
- a valid passport
- a United States passport card
- an enhanced driver's license
- a trusted traveler program card
- a valid Merchant Mariner Credential
- a valid U.S. military identification card
To cross into Canada, a traveler must carry identification, as well as a valid visa (if necessary).
Rights of Canadians
As a Canadian traveling to the US, it's essential to understand your rights at the border.
You don't have the right to an attorney in primary or secondary inspection, which means you're on your own during the screening process.
The Fourth Amendment to the US Constitution protects against unreasonable searches and seizures, but the border search exception allows CBP officials to conduct warrantless searches and seizures at international borders.
This type of search is considered a "reasonable search", which exempts CBP officers from the requirements of obtaining a warrant or establishing probable cause.

Your bags and electronics can be searched without your permission, for any reason, and CBP officials can ask you almost any question.
You have the right to remain silent, but taking advantage of this right may also leave you denied entry.
You also have the right to refuse being searched, but be aware that this may also result in denied entry.
You have the right to withdraw from the border on your own, which means you can choose not to proceed with the inspection and leave the border area.
Border Infrastructure
The border between the US and Canada is a significant infrastructure project that requires careful planning and execution. The border spans over 8,900 kilometers, making it one of the longest international borders in the world.
There are over 117 land ports of entry along the border, with the busiest being the Ambassador Bridge in Detroit, Michigan, and Windsor, Ontario. This bridge carries over 4 million vehicles annually.
A key aspect of border infrastructure is the use of technology to streamline the crossing process. The Automated Passport Control (APC) kiosks, for example, can reduce processing times by up to 75% compared to traditional manual processing.
The border also features a robust network of roads, highways, and railways that facilitate the movement of goods and people. In fact, the border is a critical trade route, with over $600 billion in goods exchanged between the two countries annually.
The US Customs and Border Protection (CBP) agency is responsible for ensuring the security and efficiency of the border. They have implemented various measures, including the use of biometric technology to verify the identity of travelers.
The Canada Border Services Agency (CBSA) also plays a crucial role in managing the border, working closely with the US CBP to ensure a seamless crossing experience.
