My understanding is that to finalize (pass) the meds, an IRCC medical officer must sign off. This is normally pretty quick.Same here. We did our medical on April 16. More than a month and no update yet. We checked with the clinic and they submitted the result on April 24. Moreover we have the status - "Your action is required" on gckey since April 24. We raised a webform and got a reply saying everything looks fine on the application and there is no additional document request made. Not sure why that status and why the delay. Even after covid offices are working remotely. I understand the delay in giving medicals or biometrics but there should not be a problem in updating online the details already sent to ircc.
But there are only a handful of them and covid obviously puts a lot more demand on them, and even one being on leave for a few weeks will cause short delays.
So nothing to worry about, but no, it's not automatic.
