Starting to get a collection of information about flying to Canada. It's probably pretty easy once you know how to do it, but until you know how to do it, it all seems very confusing.
1-800-WX-BRIEF (1-800-992-7433) In Canada try 1-877-4-TIBS-WX (1-877-484-2799) 1-888-CANPASS (1-888-226-7277) US Customs at KBFI 206-553-7960

A better way to reach the US is the new TIBS number. 1-877-4-TIBS-WX (1-877-484-2799) stands for Telephone Information Briefing Service. Again, I asked our Directors from across Canada to try this number and they all reported that it works. So here is a new tool for you to use when you are planning a trip to the US. I still recommend that you land at the first opportunity after crossing the border in order to ensure that there are no issues with clearing Customs and to top off your briefing for any pop up thunderstorms or TFRs (perhaps equally deadly?), but this new access to US flight information is a great way to plan before you leave home.
