TL;DR
IRCC updated officer instructions on April 27, 2026, extending the validity of most WP-EXT letters from 180 days to 365 days for foreign workers on maintained status.
The letters are proof of work authorization, not the source of it. The underlying right to keep working under maintained status did not change.
WP-EXT letters issued to Post-Graduation Work Permit applicants are excluded and remain valid for 180 days.
IRCC also added examples clarifying how maintained status works when a worker files a second permit application, reinforcing that timing before expiry is decisive.
Ottawa — Immigration, Refugees and Citizenship Canada has doubled the validity period of most WP-EXT letters from 180 days to 365 days, giving foreign workers on maintained status a longer window to prove they are authorized to keep working while a new permit application is processed.
The change was published in updated instructions to officers on April 27, 2026. It applies to workers who submitted a work permit application from within Canada before their previous authorization expired and who are continuing to work under section 186 of the Immigration and Refugee Protection Regulations.
What WP-EXT letters actually do
The letters do not create work authorization. They serve as documentary proof that a worker has maintained status, which is the legal mechanism that allows someone to keep working under the conditions of their original permit while IRCC decides their new application.
Workers use WP-EXT letters when employers, health insurers, or other government agencies ask for evidence that they are still authorized to work without holding a valid permit. IRCC issues the letters into applicants' online accounts after receiving the application, as reported by CIC News.
The expiry date printed on the letter does not determine how long the worker can keep working. According to IRCC's public guidance, if the department has not finalized the application by the time the letter expires, the applicant can still continue working until a decision is made. The letter's validity and the worker's legal status are separate things.
That gap between document validity and legal status is the practical reason for the update. Work permit applications can remain pending well beyond six months, and a 180-day letter could leave workers repeatedly explaining an expired document to employers even though their right to work had not changed.
PGWP applicants are excluded
The update does not apply to Post-Graduation Work Permit applicants. Their WP-EXT letters remain valid for 180 days. IRCC treats PGWP letters as a separate category, and the IRCC Help Centre confirms that PGWP applicants can still use their letter as proof of work authorization even after the 180-day validity period has passed, provided they remain on maintained status.
IRCC has also clarified cecond-application scenarios
The same April 27 update added examples that clarify rules introduced on May 28, 2025, for workers who submit a second work permit application while a first is still in play.
The central rule: a second application protects maintained status only if it was submitted before the original work permit expired.
IRCC's updated guidance addresses what happens depending on the outcome of the first application:
If the first application is still processing and the second was filed before expiry, the worker stays on maintained status and the second application may also support that status.
If the first application is refused or withdrawn, the worker may still have maintained status if the second application went in before the original permit expired.
If the first application is returned as incomplete, it does not count. Maintained status survives only if the second application was properly filed before expiry.
In all cases, a second application submitted after the original permit expired does not rescue maintained status.
What this means for temporary foreign workers
For temporary foreign workers on maintained status, the longer letter reduces the chance of having to explain an expired document to an employer or insurer while an application is still being processed. It does not extend the right to work, which already continues until IRCC makes a decision, as long as the worker applied before their permit expired, remains in Canada, and follows the conditions of their original permit.
Workers should keep a copy of their WP-EXT letter alongside their expired or current work permit.
PGWP applicants have a letter valid for 180 days, but work authorization can continue past that date if maintained status still applies.
For workers considering a second work permit application, timing is the deciding factor. It must go in before the original permit expires to have any effect on maintained status.
