U.S. Preclearance at Billy Bishop Toronto City Airport

Preclearance begins March 10, 2026

As of March 10, 2026, Billy Bishop Toronto City Airport offers a U.S. Customs and Border Protection (CBP) Preclearance facility, allowing travellers to complete U.S. immigration, customs, and agriculture inspections before departure. This means a faster, more seamless arrival in the United States.

All passengers flying to the United States will go through preclearance.

What to expect

If you are travelling to the United States, you will clear U.S. customs before your flight. When you arrive at the airport:

Check in with your airline (and check bags, if applicable)
Clear airport security with the Canadian Air Transport Security Authority
Complete U.S. CBP preclearance inspection
Relax in the transborder lounge until boarding

Once you’ve completed preclearance, no further inspections are required upon arrival in the U.S. You may proceed directly to your connecting flight or final destination.

Plan Ahead

Time

Preclearance is similar to any international customs process and can take time. Arrive early and follow your airline’s guidance.

Note: The airport is closed to the public between 11 p.m. and 5 a.m. daily. If you have a morning flight, do not arrive prior to 5 a.m. Check-in opens at 5:30 a.m.

What to bring

All travellers to the United States must have a valid passport.

Non-Canadian citizens may also require a visa. Citizens of Visa Waiver Program (VWP) countries require valid ESTA approval. Please have all required documentation on hand.

Some items are not permitted into the United States. Review the U.S. CBP’s Know Before You Visit guidance before you travel.
