According to the people in this forum, an eligibility is an indication that your application is progressing and it is on the route to a final decision. However, the eligibility process, in some cases, might take some time, at least in India. There were few applicants mentioning that it would take around 15-20 days approx. to get a decision. I am not sure about your country. In my case, my eligibility started the same day of the medical passed, which was on December 21, 2020. I have been waiting for the response since then. I think it depends on your education and career background and the country in which you have applied. I have my course starting on 17 January 2021, still waiting. We can wait and ask IRCC to expedite the process, but the time and the decision is theirs always.
