How Canadian Authorities Decide If A Non‑Resident Is Carrying On Business In Canada

Carrying on Business in Canada A Canadian tax concept used to determine whether a non-resident's business activities in Canada create specified income-tax or GST/HST obligations.

Tax administrators do not apply a single bright-line test when determining whether a non-resident is carrying on business in Canada. Instead, Canada Revenue Agency (CRA) guidance and case law use a facts-and-circumstances approach: officials examine the nature, regularity, and economic substance of activities performed in Canada and how those activities connect to revenue-generating operations.

What Decision-Makers Look For

Canada’s assessment focuses on whether the non-resident’s Canadian activities resemble the core elements of a business as carried on by a resident. Important indicators include location of contracts, presence of employees or agents, regularity of sales, use of Canadian facilities, and where the essential elements of value creation occur.

• Regularity: Repeated, organized commercial activity in Canada supports a finding that a business is being carried on.
• Substance: Activities that generate or secure revenue (sales, contract negotiation, performance) weigh more heavily than occasional marketing or promotional visits.
• Physical Presence: Permanent premises, leased offices, warehouses, or sustained employee presence in Canada increase the likelihood of being treated as carrying on business.
• Agent Status: Dependent agents who habitually conclude contracts in Canada can create a business presence for the non-resident.
• Contracts and Billing: If contracts are negotiated or accepted in Canada and invoicing or collection occurs there, that points toward carrying on business.

Why The Test Is Facts-Driven

Rather than relying on a formal registration or a single activity, Canadian courts and the CRA assess the economic reality. A series of otherwise small tasks can amount to carrying on business when they collectively create sustained commercial activity. Conversely, significant periodic activities may still fall short if the overall pattern lacks continuity or revenue connection.

How This Affects Income Tax And GST/HST

Finding that a non-resident is carrying on business in Canada can trigger two main obligations. First, for income tax purposes, the non-resident may be required to file a Canadian income-tax return and pay tax on Canadian-source business income. Second, for indirect taxes, the non-resident may need to register for and collect GST/HST on taxable supplies made in Canada.

• Income Tax: Canadian-source profits attributable to the business carried on in Canada are potentially taxable under the Income Tax Act; treaty rules may modify or limit taxation.
• GST/HST: If supplies of goods or services are made in Canada as part of carrying on business, GST/HST registration, collection, and remittance rules can apply.

Common Fact Patterns That Create Risk

Certain practical scenarios frequently lead to a CRA finding that a non-resident is carrying on business. Examples include maintaining a Canadian office or warehouse that stores inventory for domestic sales, having sales staff or agents in Canada who routinely negotiate and close deals, and performing installation or construction activities in Canada over an extended period.

• Warehousing For Domestic Fulfillment: Holding inventory in a Canadian fulfillment centre and shipping to Canadian customers can constitute carrying on business.
• Dependent Agent Sales: Using local agents who habitually conclude contracts in Canada creates exposure.
• Service Delivery On‑Site: Sending technicians to Canada for routine installations or repairs may establish a taxable presence if the pattern is ongoing.

Practical Steps For Non‑Residents

Non-resident businesses should map their Canadian activities and adopt controls to manage risk. This includes documenting where contracts are signed, the role and independence of any Canadian agents, the location of inventory, and how invoices are issued and collected.

• Record Keeping: Maintain detailed records of Canadian visits, agent contracts, and where contractual obligations are performed.
• Agent Agreements: Use clear, written contracts that define agent status and limit authority to bind the principal where appropriate.
• Supply Chain Design: Consider whether storing goods in Canada (e.g., for faster delivery) creates unintended tax obligations.
• Seek Rulings: When facts are borderline, obtain an advance ruling or professional advice to reduce uncertainty.

In short, the Carrying on Business in Canada determination rests on the economic reality of a non-resident’s activities. Regular, revenue-generating, and locally executed functions make it more likely that Canadian income-tax and GST/HST obligations will follow; careful structuring and documentation can materially reduce exposure.
