Setting Up a Subsidiary in Canada: What Foreign Businesses Need to Know
Expanding into Canada is often framed as an operational decision.
In practice, it is a structural one.
The choice between operating through a branch or forming a subsidiary determines how liability is contained, how tax is applied, and how the business is perceived by regulators, banks, and counterparties.
These decisions are often made early, with limited information, and rarely revisited once operations begin.
That is where problems start.
Branch vs Subsidiary Is Not a Formality
A branch is an extension of the foreign entity.
A subsidiary is a separate legal entity incorporated in Canada.
This distinction is not administrative. It determines whether liabilities remain with the parent or are contained within the Canadian structure.
It also affects tax treatment, regulatory exposure, and operational flexibility.
Once contracts are signed and employees are hired, changing structure becomes more complex.
Federal vs Provincial Incorporation
A Canadian subsidiary can be incorporated federally under the CBCA or provincially under legislation such as the OBCA.
The choice affects name protection, governance rules, and certain structural requirements.
In most cases, the practical differences are manageable. What matters is consistency with how the business intends to operate across jurisdictions.
Director Residency and Governance
Director residency requirements have historically affected how Canadian corporations are structured.
Changes to federal rules have reduced these constraints, while provincial regimes differ.
The practical issue is not just compliance.
It is who actually governs the Canadian entity and how decisions are documented and implemented.
Structure Before Operations
Many businesses begin operating before the structure is fully defined.
Contracts are signed. Bank accounts are opened informally. Employees or contractors are engaged.
At that point, the legal structure is no longer theoretical. It must align with what is already happening.
If it does not, the cost of correction increases.
The Role of the Parent Company
A subsidiary does not operate independently in practice.
The parent company often controls strategy, funding, and key decisions.
This creates an additional layer of obligation.
Corporate records must be maintained. Intercompany relationships must be defined. Compliance obligations must be met at the Canadian level.
These requirements are ongoing, not one-time.
Where Issues Surface
Most structural issues do not appear immediately.
They surface when something forces review.
A bank requires documentation before opening accounts. A regulator assesses whether the business is carrying on regulated activity. A transaction or audit requires clarity on structure and control.
At that point, informal decisions are tested against formal requirements.
The Practical Question
The relevant question is not whether a Canadian presence exists.
It is whether the structure supporting that presence reflects how the business actually operates.
That includes ownership, governance, funding, and regulatory exposure.
Where This Leads
Once operations begin, structure becomes harder to change.
The initial decisions continue to shape how the business is taxed, regulated, and managed.
Understanding those decisions at the outset determines whether the structure will hold as the business scales.
