I have recently applied for my PR Card renewal. My existing card is now expired (and also lost). I have a trip to the US planned for October, and I doubt I will receive my new card in time. Can I leave the country and return without this PR card? My only other forms of ID are my current Australian passport, marriage certificate and a credit card. I will be returning via car, either border crossing (Peace Arch) or via a drive-on ferry from Washington State to Vancouver Island, BC.
