That medical surveillance is done after your mother lands here in Canada. Don't worry about it for the time being.@ IHeartCanada.
Just to be clear, Biometric we have done is not for Visitor Visa, it is for PR.
My Mom's medical passed last Friday (Aug 06th) from online account status. Today I received "Correspondence Letter" document : IMM0535 Document (Medical Surveillance Undertaking). I believe it is communication to Applicant since there are no action mentioned to us to do.
If you have any insights on this scenario, please share your thoughts.
Thx
