If it takes 4 to 6 months, its fine. I would be back to Canada by then and I can travel with my current passport. My problem would be if they call for Oath 5 or 10 days before my travel.. where I would become Canadian citizen and cannot travel with my current passport and will not have enough time to get the Canadian passport.Doubt it. Scarborough is one of the slowest offices to schedule oath. Typical wait time after DM is 4-6 months for oath. You may get lucky due to cancellations, never know.
