Hi,
CPP Ottawa is currently processing applications received on December 13. Your application is either in process or about to be processed. The way I see it would be a pretty close call as you already have flights booked for Jan 13.
In case you don't receive your passport by January 12 I advise that you call your travel agent and instead of cancelling the entire ticket request him to release the seat confirmed for outbound provided you bought a ticket that allows changes. That way you would need to pay only a change fee rather then a cancellation fee that is generally higher than a change fee. Alternatively you could cancel this ticket if there are much cheaper fares available for travel on a future date.
Hope this helps.
