What document is required for planning a flight to Canada as of January 2007?

For planning a flight to Canada, a passport is the primary document required. A passport serves as an official form of identification and proof of nationality, which is essential for all international travel. Since January 2007, travelers have needed to present a valid passport when entering Canada, ensuring that they are properly identified at border control and complying with international travel requirements.

While visas may be necessary for some travelers, depending on their nationality, the general requirement for all travelers, including those from the United States, is to have a passport. Airline tickets and travel insurance may be important for planning the logistics of the trip but do not serve as identification or proof of citizenship at the border. Thus, while they may facilitate the journey, they do not fulfill the fundamental requirement of entry into Canada. Therefore, the passport is the correct document needed when planning a flight to Canada.
