I'm going to email Sydney later in the month to inform them of the situation. Not that they care but more interested once the visa is approved can I just go to my nearest embassy in Ontario to deal with PPR and CoPR (then do a border exit/entry) or do I have to send everything to Sydney, or does sydney transfer everything back to Canada. All very interesting.
I know at the border they will ask the standard question "If you visa is not approved, what proof do you have now you will leave" as we are on a oneway ticket etc. My only answer is I will leave Canada to reapply so i can re enter later without problems. I hope thats enough...
If you are to get PPR when you are in Canada, you can send your passport to the nearest VO. If you are going to Ontario, it is Ottawa VO that will process your CoPR. I know of a relative who did that, so you should be fine with that. Good luck! Hope everything works out for you
