without your current Canadian work experience, is your score 467? If so, retake ielts or celpip to boost your score.
According to the website of the government,
Employment Insurance (EI) provides regular benefits to individuals who lose their jobs through no fault of their own (for example, due to shortage of work, seasonal or mass lay-offs) and are available for and able to work, but can't
find a job.
Always apply for EI benefits as soon as you stop working. You can apply for benefits even if you have not yet received your Record of Employment (ROE). If you delay filing your claim for benefits for more than four weeks after your last day of work, you may lose benefits.
In other words, you are currently unemployed and will receive EI from the government instead of paycheque from your ex-employer. It means you are 7 weeks short from completing 1 year Canadian work experience.
Regarding to your question about if your work permit is extendable, it depends. If you are currently holding a post-graduate open permit, then the answer is no. But who know, IRCC may extend your due to COVID-19. Another way to extend is would be your employer get a LMIA approved and apply a work permit for you.
These are just my thoughts may not be accurate.
