Thanks @tar86 for the info. Mine got expired in July and till now nothing updated in the portal. It's been like 3 months..maybe will get to know in few more months....last gcms notes show appears RFV which was updated this year January...nothing after that..frustratingMedical is valid for one year after first time your application is assessed by an agent- means at the time of application completeness check, which is the first stage in PR application process.
IRCC extend medical for further one year depending upon the country of residence. If it is extended, you normally get status change in your GC account, where your new medical pass date is updated.
