UN Experts on Mission in Canada: 2026 Work Permit Update [R205(a) – C10]

Experts on Mission Working for a United Nations Office in Canada: A Complete Guide

If you are a foreign national invited by a United Nations office in Canada to work as an expert on a short-term mission, you may need a work permit—even if you are not a diplomat. This guide explains exactly what the Canadian government requires, how to apply, and what privileges you may still enjoy. All details below are based on official IRCC program delivery updates as of April 27, 2026.

Who Are Experts on Mission?

Officials of a UN office in Canada are internationally recruited staff who are sent on posting. They enjoy immunity from immigration restrictions, including work permit requirements, for themselves, their spouses, and dependent relatives. However, experts on mission are different. They are non-accredited foreign nationals engaged by a UN office for a short period. They do not enjoy full diplomatic immunity and are subject to Canada’s Immigration and Refugee Protection Act (IRPA) and Regulations (IRPR).

Experts on mission normally obtain an accreditation similar to a diplomatic accreditation from the Office of Protocol (XDC) at Global Affairs Canada (GAC). But when they are not accredited, they must follow regular immigration procedures.

Work Permit Exemption Under Global Skills Strategy

Experts on mission coming to Canada for short-term assignments may be eligible for a work permit exemption under the Global Skills Strategy. This applies only if the job is in Training, Education, Experience and Responsibilities (TEER) categories 0 or 1 in the National Occupational Classification (NOC). The exemption allows work for:

• Up to 15 consecutive days once every 6 months, or
• Up to 30 consecutive days once every 12 months.

If your assignment is longer than 15 or 30 consecutive days and you intend to reside in Canada, you must follow a case-by-case process. The IRCC office processing your work permit will coordinate with the XDC. If the XDC gives written consent—considering your distinguished expertise and the importance of your work at the UN—you may be eligible to apply for a work permit under the significant benefit provision (R205(a)) and LMIA exemption code C10.

Key Conditions and the Host Country Agreement

A legally-binding agreement between the Government of Canada and each UN office in Canada—called the “host country agreement”—determines the privileges, immunities, and conditions for the UN office and its staff. Officials of a UN office who are internationally recruited and posted enjoy immunity from immigration restrictions, including work permit requirements. Experts on mission who are not accredited do not share this immunity.

Overseas Application Process: Step by Step

To apply from outside Canada, follow these official steps:

1. The international organization (your employer) contacts the XDC to obtain written confirmation by email.
2. If the XDC has no concerns, it sends an email with a clear subject line: “Experts on Mission – C10 LMIA exemption” to the organization.
3. The XDC confirms with the organization which visa application centre (VAC) you will use.
4. The XDC shares your name and the VAC information with the Migration Program manager.
5. The Migration Program manager coordinates with the VAC to receive your paper application.

Even if you are visa-exempt because of your country of origin, the XDC encourages you to apply to a VAC or migration office overseas. Submit the email confirmation from the XDC with your paper application.

Requirements for the Work Permit (C10 – R205(a))

To be eligible under paragraph R205(a), administrative code C10, you must:

• Submit a complete application, including all fees.
• Submit the written confirmation received from the XDC.
• Submit documentary evidence, such as an employment contract that shows job details, duration of work, and start and end dates.
• Undergo all admissibility assessments, including security screenings, criminality checks, and medical examinations (as required).

Officers will require the following documentary evidence:

Employer Compliance Regime Exemption

UN offices in Canada are foreign missions and international organizations. They are exempt from the employer compliance regime. This means no offer of employment or employer compliance fee is required to be submitted via the Employer Portal.

Port of Entry (POE) Application Process

If you are otherwise eligible to apply at a port of entry, you may apply for a work permit when seeking entry to Canada. All regular processes and required documentation (listed above) apply to POE applications as well.

In-Canada Application Process (Extensions)

If you are already in Canada and your initial work permit is about to expire, you may apply to a case processing centre for a work permit extension. When reviewing extension applications under C10, officers require:

• A new written confirmation from the XDC that clearly outlines the new duration of employment.
• All documentation and regular processes that apply to overseas applications.

Work Permit Issuance

If your application is approved, your work permit will be issued for the duration confirmed by the XDC or until the expiry of your travel document, whichever is earlier.

Dependants of Experts on Mission

Dependants are not included in the C10 exemption. They do not receive any confirmation or facilitation from the XDC. However, they may submit their applications alongside the principal applicant to the same VAC or IRCC office. Their applications will be processed concurrently under existing IRCC programs.

For example, spouses may be eligible for an open work permit under exemption code C41, as the spouse or common-law partner of a skilled worker. All applications from dependants are assessed on a case-by-case basis.
