I was earlier planning on applying visa for Sept 2020, so got my medical done in February. But due to the corona virus, I decided to defer it to winter 2021. I applied for my visa in september and till now, I haven't heard anything from IRCC. Got my biometrics done on september 15 and no update since then. My medical was valid for one year and it will expire in February 2021. The way things are moving I have very little hope of getting my visa till February. What will happen if my medical expires and they still haven't updated the medical?
