Toronto Pearson (YYZ) Connection Risk: How Much Time Do You Really Need Between Flights?

Why Toronto Pearson Is One of the Hardest Airports for Connections

Toronto Pearson (YYZ) is Canada’s busiest airport, handling over 40 million passengers per year and thousands of daily connections. But with its multiple terminals, long walking distances, and frequent delays, connecting flights here are among the highest-risk in North America.

Our Flight Connection Predictor analyzes live flight data, gate distances, and security queues to estimate your chance of making the next flight — and YYZ consistently ranks as one of the top 5 riskiest airports for tight layovers.

Real-World Example

A traveler arriving from Vancouver (YVR) to YYZ and connecting to New York (JFK):

  • Arrival at T1 domestic

  • Connection at T1 international

  • Typical gate-to-gate walk: 14 minutes

  • Average security delay: 18 minutes

  • Recommended connection time: at least 75 minutes

If your layover is shorter than that, our API predicts a >25% chance of missing your connection.

How the Connection Risk Is Calculated

The Flight Connection Predictor uses:

  • Real-time flight status (delays, taxi-in time)

  • Gate distance and terminal mapping

  • Immigration and security buffer models

  • Historical misconnect data

It produces a probability of misconnection between 0 and 1 (e.g., 0.23 = 23% risk).
