I am interested, too, since my oath should be coming up this summer and I have a fairly intensive travel schedule.
I have to say, I find it inconceivable that the process is this slow. Because if you have to wait 2 business days before your name is in the system, and then the quickest you can get the passport is in 2 business days, even if you pay for the urgent procedure, that means 4 business days, almost a week. There are people who NEED their passport to work (I'm thinking pilots, cabin crew, transportation personnel, transborder truck drivers), without mentioning business people with fairly hectic travel schedules, I don't find it acceptable that the Canadian government tell these people "you can't work for a week because we need to get our sh*t together".
I can't see why Canada cannot have a procedure, like they have in the UK, where you can get your passport on the same day, and why there can't be an expedited way to have your name appear in the system if you need your passport ASAP. Even if there is a charge, I'm sure quite a few people would be happy to pay to get it done quickly.
