Friends: I apologize for my stupid Question about Canada NAV fees. The invoice from Canada NAV took me by surprise when I was catching up on old bills and I was in a grouchy mood. The Canada NAV customer service was closed for the day, so I ran like a little baby to Mooney Space to ask what I now know was a stupid question. Also I don't like the idea of User Fees for flying, so that was a contributing factor to my panic. Also I got bad info on the internet and I was under the false impression that once I go to Canada, I owe quarterly User Fees as long as I own my airplane. Anyhow, the info was readily available online and I spoke to Canada NAV customer service and paid my bill and asked how the fees work. They are not really that bad and I will continue flying to Canada. I love the flight from Caldwell, NJ to Billy Bishop City Island Toronto Airport. Again, I apologize for what was a stupid question. Everybody have a great day and enjoy your flying. Respectfully - RonM
