Some individuals pay different fees for the TRP, which is determined on level of offense by officials...I had Alaskans tell me one paid $250 to drive to Haines as she had to attend her grandmother's funeral in Juneau, one had paid $500 for an in transit to the states, one had quoted a $1500 fee just to submit the application ...and still not guaranteed for approval, which that person withdrew their application for entry into Canada and immediately returned to Alaska.
Likewise, depends on one's individual status and level of offense.
