The charge is normally $10.75 for each trip into Canada IF you don't have a transponder,which costs around $200. per year. Sometimes the agents don't ask you for it when I give them my Fast card for i.d. Whether it is because some of them forget to collect,don't know to collect,or some assume since I have Fast card that I have transponder and don't bother to ask for fee, I don't know. If you don't go into Canada a whole lot and have Fast card it might be cheaper to not get transponder. Yes they can be rude usually once in awhile. Let's see: Didn't park close enough to the booth, didn't show enough eye contact. gave agent b.o.l. and when going intransit through Canada was told don't ever give them something paperwork that the driver needs back. All the above examples were told to me in a very condescending manner. Ever so often you will meet an agent who is having a bad day and will look for a reason to take it out on someone.
