The short answer is no. It isn't impossible. As I've said several times, my department introduced measures to help temporary visitors, both workers and students. We made the system much more flexible to expedite the approval of applications.
Before the COVID-19 crisis, if you applied for a work permit, you had to wait several months. With respect to the essential worker category, our process is much faster now. However, I know that there's a great deal of pressure with regard to this priority. We'll keep working on it.
