There are many reasons why you could face delays or issues when travelling by plane. If you’re not sure why you were delayed or denied boarding at the airport on a recent trip, the first step is to call your air carrier. They may have more information on why you were delayed.
A CTN prevents delays at the airport only for travelers who have a similar name as someone on the Secure Air Travel Act (SATA) list (sometimes called Canada’s “No Fly List”).
It is important to note that a CTN will not help with any other type of travel delay, including but not limited to: issues related to specific immigration or admissibility-related matters; expired; incomplete or inaccurate travel documents; amendments to travel records; and/or, any biometric record issues.
A CTN is not mandatory for travel, and is used only as an additional piece of information to help prevent SATA-related delays when traveling by air to, from, and/or within Canada.
