BOC-3 filing for Canadian carriers
If you run a Canada-domiciled motor carrier into the US, you must designate a US process agent in every state under 49 CFR Part 366 - US-Canada reciprocity gets you the operating authority, but it does not waive the BOC-3, and no Canadian address is accepted on the form. We file it the same business day for $75 flat, one-time, covering all 48 contiguous states plus Hawaii and DC.
File your BOC-3 - $75Reciprocity gets you the authority - not a BOC-3 waiver
Under the long-standing US-Canada arrangement, a Canada-domiciled carrier is treated far more favorably than a fully foreign applicant: you can obtain US interstate operating authority and an MC number to run into the United States. That reciprocity covers the authority to operate. It does nothing to the separate federal requirement to name an agent for service of process.
The statute is explicit: 49 USC 13304 requires every motor carrier operating in the United States in the course of transportation between points in a foreign country to designate an agent in each state on whom legal process may be served. The implementing rule, 49 CFR Part 366, puts that designation on Form BOC-3. A Canadian carrier is squarely inside that population the moment it crosses the border with US authority.
The result is identical to what a US carrier files: the same form, the same blanket of state coverage, and the same $75 flat fee. What differs is everything around the BOC-3 - your application path, your insurance filing under Part 387, and a handful of cross-border details below.
Why no Canadian address works on the form
Every listed agent has to be inside the United States
The whole point of the BOC-3 is to give a US plaintiff a single, in-state address where service of legal process is effective. US courts cannot reliably serve documents into Canada, so a process agent in Ontario, Quebec, Alberta, or BC does not satisfy 49 CFR Part 366 - even if that person is willing to accept the paperwork.
- Your Canadian head-office address belongs on your US authority record - it does not go in the BOC-3 process-agent fields.
- A motor carrier with commercial motor vehicles cannot self-designate (49 CFR Part 366), so a Canadian carrier cannot name itself even at a US address.
- A blanket US provider listed in FMCSA process-agent records covers all 50 states at once - the only practical answer for a carrier with no US corporate footprint.
Roles that look similar but don’t count
Canadian carriers often assume an existing relationship covers the BOC-3. It doesn’t. Your provincial registered agent is a corporate-law role at home. Your US customs broker clears freight at the port of entry. Neither is a designated agent for service of process, and neither appears on FMCSA process-agent records. The BOC-3 is its own federal filing, and only an FMCSA-registered process agent can submit it.
Where the BOC-3 fits in your US filing stack
For a Canadian property carrier seeking US authority, the BOC-3 is one piece of a short sequence. Get it on file early - it is the cheapest item and the one most likely to stall activation when it is missed.
- 1
US operating-authority application + FMCSA fee
Filed under the US-Canada reciprocity path. Once accepted, you are issued an MC number and enter the population required to designate process agents.
- 2
BOC-3 designation - $75 one-time (this is us)
Submitted by your blanket US process-agent provider. Lifetime, no annual renewal. See how to file a BOC-3.
- 3
Financial responsibility under 49 CFR Part 387
Your US insurer files proof of public-liability coverage (the BMC-91 or BMC-91X form for property carriers) directly with the FMCSA. Household-goods movers also pick up Part 375 consumer-protection obligations.

UCR registration
Canadian carriers operating into UCR-participating US states owe the annual federal-state fee just like domestic carriers. File at FastUCRFiling.
Cross-border pitfalls Canadian carriers hit
Designating only the border states you drive through
A carrier crossing at Detroit-Windsor or Buffalo-Fort Erie isn’t exposed only in Michigan or New York. If your authority lets you deliver into the interior, a claim can arise in any state. A blanket designation closes that gap - one filing, every state.
Legal-name mismatch between the Canadian entity and the US record
The legal entity on the BOC-3 has to match your US authority record character-for-character. If your operating name carries an “Inc.,” “Ltd.,” or accented characters, confirm exactly how it was filed on the US side before the BOC-3 goes in. We catch most of these on intake.
Assuming cabotage and BOC-3 coverage are the same thing
Cabotage rules - which limit point-to-point moves between US cities for a foreign carrier - sit in customs and immigration law, not in 49 CFR Part 366. Expanding your BOC-3 won’t let you haul more domestic loads. The two are governed entirely separately.
Canadian carrier BOC-3 questions
Do Canadian carriers need a BOC-3 to operate in the US?
Yes. Any motor carrier operating in the United States in the course of transportation between points in a foreign country must designate a US process agent under 49 CFR Part 366, with the underlying statutory requirement at 49 USC 13304. The US-Canada reciprocity arrangement lets a Canadian carrier obtain US operating authority (an MC number) more easily than a fully foreign applicant, but it does not waive the process-agent designation. If you cross into the US to pick up or deliver, you need a BOC-3 on file.
Can I list my Canadian business address on the BOC-3?
No. The BOC-3 designates a person or company physically present in each US state who can accept legal service of process. A Canadian address - in Ontario, Quebec, Alberta, or anywhere else - does not satisfy 49 CFR Part 366, because US courts cannot reliably serve documents across the border. That is the entire reason the process-agent system exists. Every agent listed on the form has to be inside the United States, which is why nearly all Canadian carriers file through a blanket US process-agent provider.
Is a Canadian registered agent or my US customs broker enough?
No on both counts. A Canadian registered agent is a corporate-law role in your home province and has nothing to do with US service of legal process. A US customs broker clears your freight at the border but is not a designated agent for service of process and is not listed on FMCSA process-agent records. The BOC-3 is a separate, federal designation that has to be filed by a process agent who is recognized by the FMCSA - it does not overlap with either role.
Do I only need process agents in the border states I drive through?
No. While 49 USC 13304 is framed around the states a foreign carrier traverses, the practical and compliant approach is a blanket designation covering every state where you could be sued. A Canadian carrier whose authority lets it deliver into the US interior is exposed to legal service well beyond the border states it physically transits. A blanket BOC-3 covers all 48 contiguous states plus Hawaii and DC in one filing, so you are never short an agent in a state where a claim could arise.
How much does a BOC-3 cost for a Canadian carrier?
The same $75 flat, one-time fee we charge US-domiciled carriers. There is no cross-border surcharge, no per-state fee, and no annual renewal. The $75 is the total cost of the BOC-3 line item - your US operating-authority application fee, your Part 387 insurance filing, and any other FMCSA charges are separate and paid directly to the agency.
Does the BOC-3 affect cabotage or what loads I can haul in the US?
No. Cabotage rules - which limit the point-to-point movements a foreign carrier can perform between US cities - live in US customs and immigration regulations, not in 49 CFR Part 366. The BOC-3 only designates who accepts legal service of process for you in each state. It does not grant, expand, or restrict cabotage rights, and adding states to your designation will not change which loads you are permitted to move.
