Same process that is being listed now. Raise webform when you know you cannot/will-not travel to inform them.Could you pls ask ur frend exactly what process did they follow for extension.He got extension from his hime country embassy or ircc Canada?And in how much time did they give extension.Sorry for so many q.But as u know we r too stressed.Thanks.
In her case since it was before all the pandemic, they replied to her and told her to raise webform when you are ready to travel and we will tell you process to redo medicals and PCC and resubmit COPR + passport, thats it. She is in the US, got extension from IRCC Canada.
I know it is a stressful time for us all, and we would love an individual response to our webforms or a blanket statement from IRCC , but it seems like we all have to trust that the process will work out for now.
