You are required to provide advance notification to CBSA by calling 1-888/CAN-PASS (226-7277). You must provide notification no less than two (2) hours but no more than 48 hours prior to your arrival. A filed and activated flight plan is required for border crossing, and your first landing in Canada must be at an airport of entry. You will be required to provide the customs office with information about yourself, your passengers, your flight, and your airport of entry. After arrival at your airport of entry, if there is no customs officer present, immediately contact the Canadian CANPASS office again at the same number and receive an arrival report number or be advised to await a customs inspection.
When you call Can-Pass (1-888-can-pass) at the first time, they will ask you all sorts of questions (all basic), you will get a report number after your arrival in Canada.
The registration for fire arms is $25 every 60 days.
Thanks to an agreement between the FAA and Transport Canada, flying an experimental aircraft into Canada is now easier than ever. All that is needed is the document Standardized Validation of a Special Airworthiness Certificate—Experimental, for the Purpose of Operating a United States-Registered Amateur-Built Aircraft in Canadian Airspace which details the restrictions (minor in nature) applicable in Canadian airspace. Download the form and carry it with the aircraft at all times in Canada.
