As you probably know, you can fly your own Canadian aircraft in the United States and American pilots can fly theirs into Canada, but that only applies to any Canadian registered aircraft. There is a process to obtain a Canadian (TCCA) licence if you already hold an American (FAA) certificate.

A U.S. private pilot can certainly fly to Canada, provided they meet specific documentation and procedural requirements. The pilot-in-command must possess a valid Private Pilot Certificate with an "English Proficient" endorsement and a current medical certificate (note that BasicMed is generally not accepted for international flights). Essential documents include a valid passport, a restricted radiotelephone operator’s permit, and an eAPIS filing (Electronic Advance Passenger Information System) at least one hour before departure. The aircraft itself must have a standard airworthiness certificate, permanent registration (no "pink slips"), and a DHS decal affixed to the window. Additionally, you must carry proof of liability insurance that meets Canadian requirements, often specified in Canadian currency. Before crossing the border, pilots must file an international flight plan and contact CANPASS to receive a unique arrival ID. All international flights must initially land at a designated Airport of Entry (AOE) to clear customs and immigration, making a flight to Canada an achievable yet detail-oriented adventure for any qualified general aviation pilot.
