Fees and service standards

Fee Structure

The fee structure includes both hourly fees and hybrid fees depending on the type of application:

  • hourly fees (Table 1):
    • are charged for every hour a Transport Canada employee takes to process your application
    • there is a maximum number of hours we can charge for
    • this maximum is calculated by fiscal year which starts on April 1 and lasts until the following March 31
    • once we reach this maximum, you won’t be charged for any additional hours within the same fiscal year
    • charges will resume April 1 of the next year with the count of hours restarting at zero
    • hourly maximums vary based on the service type (Table 2)
  • hybrid fees include fixed and hourly fees:
    • an initial fixed amount that covers up to 300 hours of work on an application (Table 3)
    • an hourly fee for additional hours if an application takes more than 300 hours of work (Table 4)
    • number of additional hours are limited by service type (Table 5)
    • the same calculation methods apply as hourly fee described above
