Due to the pandemic, visitors who are currently in Canada and have a valid job offer will be able to apply for an employer-specific work permit and, if approved, receive the permit without having to leave the country.

However, the applicant must

• have valid status in Canada as a visitor on August 24, 2020 and remain in Canada
• have a job offer
• submit an application for an employer-specific work permit that is supported by a Labour Market Impact Assessment (LMIA) or an LMIA-exempt offer of employment, no later than March 31, 2021
• meet all other standard admissibility criteria
