Invitation Letters for Business Visitors – Notarization in Ontario
Invitation Letters for Business Visitors – Notarization in Ontario
Invitation letters are a key requirement for Canadian businesses planning to host foreign nationals for business-related visits. These documents are often reviewed during visa processing to verify the purpose of the visit, the relationship between the parties, and the hosting company’s intent.
To meet the
expectations of Immigration, Refugees and Citizenship Canada (IRCC), notarizing your invitation letters adds legal credibility and ensures they are properly executed under Ontario law.

What Is a Business Invitation Letter?
A business invitation letter is a formal document issued by a Canadian company to a foreign national, stating the purpose of the visit, the intended duration of stay, and the host company’s details and commitment. These letters are typically required when applying for a Temporary Resident Visa (TRV) for business-related activities.
To ensure the letter is accepted by IRCC and foreign consulates, it should be clearly written, signed, and properly notarized.
Who Requires a Notarized Invitation Letter?
Canadian businesses may need notarized invitation letters when they are:
- Inviting foreign nationals for business meetings or negotiations
- Hosting partners for conferences, training sessions, or executive visits
- Supporting collaborative projects or international joint ventures
These letters help immigration officers confirm the legitimacy of the visit and the credibility of the host organization.
Why Notarization Matters
For immigration purposes, notarization verifies that the letter was:
- Signed by an authorized representative of the Canadian business
- Witnessed by a licensed Ontario Notary Public
- Executed in compliance with Ontario’s Notaries Act
Without notarization, visa officers may question the validity or authenticity of the document, potentially delaying or rejecting the application.
