CBP Preclearance Now Available at Billy Bishop Toronto City Airport
Key Takeaways
- It has been reported that CBP (U.S. Customs and Border Protection) preclearance operations launched at Billy Bishop Toronto City Airport (YTZ) effective March 10, 2026.
- U.S.-bound travelers departing YTZ will complete U.S. immigration and customs inspection in Toronto and arrive in the U.S. as if on a domestic flight.
- It has been reported that Canadian citizens may now apply for TN (USMCA professional) and L-1 (intracompany transferee) admission during preclearance at YTZ; previously L-1 admission was not available from that airport.
- Travelers should ensure they have the correct documentation (TN letter or USCIS-approved I-129 for most L-1 admissions) and consult an immigration attorney if unsure.
What changed
It has been reported that on March 10, 2026, CBP preclearance became operational at Billy Bishop (YTZ) in downtown Toronto. Preclearance means U.S. immigration and customs inspections are completed in Canada before boarding; once admitted there, passengers generally clear domestic arrival procedures in the United States. Canada now has ten airports offering preclearance, and Billy Bishop will operate its program independently from Toronto Pearson International Airport.
Who is affected
The most immediate beneficiaries are U.S.-bound travelers from downtown Toronto, including business travelers who value time savings and predictability. It has been reported that Canadian citizens can now apply for TN and L-1 admission at YTZ during preclearance. A quick legal note: TN status (under the USMCA, the United States–Mexico–Canada Agreement) allows qualified Canadian professionals to seek temporary entry at the border with employer documentation; L-1 status is for intracompany transferees and in most cases requires an approved USCIS (U.S. Citizenship and Immigration Services) Form I-129 petition or an approved blanket L prior to admission. That distinction matters: TN can often be sought at the port of entry with a job letter and supporting docs, while L-1 typically requires prior USCIS approval except in narrow circumstances.
Practical next steps and human impact
For travelers planning to use YTZ preclearance: carry a passport, a detailed employment letter or I-129 approval notice (for L-1), and any supporting contract or licensing documents for TN professionals. Understand that preclearance can speed your entry into the U.S. and reduce arrival wait times, but CBP can refuse admission during preclearance — which may prevent boarding. This change does not alter USCIS adjudication standards or processing times for petitions; it simply gives more flexibility on where admission interviews occur. If you are relying on L-1 or TN admission for travel or employment start dates, consult a qualified immigration attorney to confirm documentation and strategy before traveling.
