I did upfront medicals last week and just received this email.
Dear Sir/Madam,
Your medical exam results have been received by our office and your application is going through the required assessment process.
An officer will contact you if additional documents are required. Please ensure when submitting documents that they are still valid and will not expire within six (6) months as this will delay your application.
We appreciate your patience and keeping correspondence with our office to a minimum and up to date. In order to process request efficiently, we will not be responding to duplicate requests.
Regards,
