Best Nonstop Flights to Toronto Pearson YYZ, Ranked for Reliability

Flying to Toronto Pearson (YYZ) without a connection is the most dependable way to start a tight itinerary—but not all nonstops are equally reliable. Below, Travel Beyond Boundaries ranks the best nonstop flights to Toronto Pearson for reliability in 2025–26, prioritizing on-time performance, cancellation history, and schedule redundancy when route-level data isn’t public. Our picks lean on carrier-level OTP and U.S. reliability indices as proxies, then layer in network resilience. Reliability isn’t the same as the best seat or lowest fare, and it can vary by season or time of day. For time‑critical trips, recheck day‑of on-time performance before you leave and favor morning departures.
