Can a Canadian Own a Business in the US? Yes, With Limits

Ownership is the easy part, and it is the part every guide answers. The harder question, and the one that actually stops cross-border expansions, is who is allowed to work in the company once it exists.

Can a Canadian own a business in the US?

Yes. Canadian companies have several options for establishing a U.S. presence, and the right structure depends on legal, tax, operational and immigration considerations. Invest Buffalo Niagara can connect companies, free of charge, with experienced cross-border legal, accounting and financial professionals who can help determine the appropriate approach.

What ownership does not settle is who can work in the company once it exists. Ownership and authorization to work in the U.S. involve different considerations, and treating them as one question is the most common mistake we see. A company can be formed, funded, registered and banked while nobody is yet able to run it on the ground.

The four things a Canadian company works through, in the order they usually matter:

• A US entity, formed in a state, with a registered agent in that state.
• A federal tax ID (EIN) from the IRS.
• Work authorization for anyone who will actually work in the US operation.
• A cross-border tax position agreed with an accountant before you file.

Who can work in the US operation

This is where most guides stop being useful, because they answer the ownership question and then hand you a call to action.

You can own the company from Toronto, direct it and visit for meetings and site tours. Having your own people work in the US operation is a separate question. Ownership and authorization to work in the U.S. involve different considerations, and Invest Buffalo Niagara can connect companies with experienced immigration counsel to evaluate the appropriate options for owners, executives and employees.

The practical point: raise the immigration question with counsel at the same time as the entity structure, not after it. Companies that incorporate first and ask about moving people second sometimes find the structure they built does not support the move they wanted, and unwinding it costs more than planning it.

Two steps that take longer than people expect

Two specifics are worth knowing before you start, because both cost time rather than money and both surprise people.

The federal tax ID. For owners outside the US it usually takes longer than the online route most guides describe, and bank accounts, payroll and vendor onboarding all wait on it. Start it early, and ask your cross-border accountant to handle the application.

State registration is separate from formation. Forming an entity in one state does not authorize you to operate in another. If you form in Delaware and put a facility in New York, you register in New York as well. New York also has a publication requirement that applies to LLCs specifically, which we cover in incorporating in New York.

Canadian companies that have already done it

The reason to read this from an economic development organization rather than a law firm is that we handled the projects. Invest Buffalo Niagara has helped 120 Canadian companies expand into the US. Eleven of them are documented on this site with what they invested and what they got.

What those eleven show is that the eligibility question was never the obstacle. The obstacles were the site, the transfer of people, and the incentive stack.

• Worksport, a publicly traded manufacturer of truck tonneau covers, wanted a US site close to its Canadian headquarters so it did not have to split its management team. West Seneca, New York: 308 jobs and $21.5 million invested. It has since made West Seneca its headquarters while keeping its presence in Canada.
• Pride Pak, headquartered in Mississauga, processes fresh vegetables and needed US capacity as US sales grew. Medina, New York: 206 jobs and a $36.9 million plant.
• AMDOR: 28 jobs and $5.5 million in Lancaster, New York.
• Electrovaya, a Mississauga lithium-ion battery manufacturer, chose the region for proximity and assembled an incentive stack that included Empire State Development Excelsior Jobs Tax Credits, a New York Power Authority hydropower allocation, and property, mortgage and sales tax abatements.
• PatCom Medical, an early-stage medical device company, had 80 percent of its sales in the US and needed a physical American presence to keep them.
• Sucro Sourcing did not commit first. It ran a pilot project in the Gateway Trade Zone, and only then made the permanent move. It was also considering Miami.
• FroggaBio, a Toronto laboratory products distributor, incorporated in the US in 2013 without taking premises, then came back to the physical question later.
• GoGoPak, Microart, SWS Warning Lights and Magic White completed the same move.

Two of those are worth pulling out, because they answer a question the SERP does not.

Sucro and FroggaBio both prove you can stage this. A pilot inside a trade zone, or a US entity with no premises, are both legitimate intermediate steps, and neither commits you to a building. If you are testing whether US demand is real, you do not have to answer the whole question at once.

Worksport is the clearest statement of why border proximity is a structural decision and not a nice-to-have. The company went looking for a site near its own headquarters, deliberately, because the alternative was moving or duplicating its leadership.

Where you incorporate matters less than where you operate

Most guides on this topic spend their length on choosing a state of incorporation, usually with a paragraph on Delaware. For a company whose US operation is a real facility with real employees, that emphasis is backwards.

Incorporation is a form and a fee. Where you operate determines your property tax, your energy cost, your labor market, your logistics, and how often someone from head office has to be there. Those are the numbers that compound.

For a Canadian firm specifically, the last one is the one that gets underweighted at decision time. Buffalo Niagara is roughly 30 minutes from the border and within a two-hour drive of southern Ontario’s manufacturing belt, which means a US operation without relocating leadership or splitting a team. Someone can be at the US site in the morning and back at head office the same afternoon.

The region has seven international ports of entry, certified Foreign Trade Zones, and it sits within 500 miles of 40 percent of the US population. The Buffalo gateway handled nearly $79 billion in U.S.-Canada freight in 2025, reinforcing the region’s role as one of the most important commercial crossings between the two countries. Manufacturers pay no New York State corporate income tax, no inventory or personal property tax, and no sales tax on production or research equipment.

None of that is an argument for incorporating in New York rather than Delaware. It is an argument about where the plant goes, which is the decision that actually costs money.

Questions Canadian owners ask

Can a Canadian own an LLC in the US?

Yes. Whether an LLC or a corporation is the right structure depends on tax and legal considerations on both sides of the border, and it is expensive to change later. It is the decision most worth an hour with a cross-border accountant before you file, and we can introduce you to firms that do this work, free of charge.

Can a Canadian citizen do business in the USA?

Yes. You can own a US company, sell into the US, contract with US customers and visit for business meetings. Working inside the US operation is a separate question, and we can connect you with experienced immigration counsel to evaluate the options.

Can I move to America if I buy a business?

Not automatically. Owning a US business does not by itself give you the right to live in the United States. Whether any route fits your situation is a question for immigration counsel, and we can introduce you to firms that handle cross-border moves.

Is it easier to start a business in the US or Canada?

Formation is straightforward in both. The asymmetry for a Canadian company is that the US market is roughly nine times larger, and that a US presence removes tariff, currency and “Made in USA” friction from selling into it. The cost is a second set of tax and employment obligations, which is real and ongoing.

Do we need a US office to start?

No. A registered agent satisfies formation. Many Canadian companies start with a presence rather than premises, and the coworking spaces in the region are a common first step, several of which handle mail for Canadian firms establishing a US address. Our guide to coworking in Buffalo Niagara lists them.

Will we be taxed twice?

The Canada-US tax treaty is designed to prevent double taxation, but you will still have filing obligations on both sides of the border, and your structure determines how they interact. Budget for a cross-border accountant as part of the expansion rather than as an optional extra.

What we do, and what we are not

Invest Buffalo Niagara is a privately funded nonprofit economic development organization. We are not a law firm, an accounting firm, an immigration adviser or a brokerage, and nothing above is legal, immigration or tax advice. Those decisions belong with licensed professionals, and helping you find the right ones is part of what we do.

What we do is remove the legwork. Site and building searches, labor market and demographic data, incentive applications and filings, and introductions to the cross-border immigration counsel and accountants who handle the specifics. We take no commission on any transaction, so the shortlist you get is the one the data supports.

All of it is free and confidential, whether or not you choose the region. Most of the companies we work with are still comparing options when they first call, which is the right time to call.
