You can not and You are not allowed to use portal outside Canada. It is only for in Canada people. If you receive email of portal, reply back about your current address as mentioned in that email. In most cases, they transfer application to that country. However, they will never inform you about transfer. If you have valid TRV, you can travel back to Canada before it expires. Carry copy of email of portal and show at airport if they ask anything.
if your Trv has expired while you are outside Canada, contact to canadian visa center in your country and send them email you got from ircc of portal and they will advice you what to do.
You can only get PRTD when you have COPR. copr can only be got after confirming your presence in Canada.
2. traveling outside canada while waiting for ecopr - can i apply PRTD and come to canada after ecopr comes or what to do in this case
