Official Environment Canada observations at Toronto Pearson International Airport confirm the highest temperature on April 12, 2026, reached 7°C, driving trader consensus to near-certainty on this outcome amid preliminary hourly data showing peaks of 6–7°C under mostly cloudy skies with light rain and southeasterly winds. Persistent cloud cover and showers from a cool upper-level trough suppressed daytime heating, aligning with pre-event model consensus from the Global Environmental Multiscale model forecasting highs near 8°C but delivering below-normal values versus the April climatological average of 11°C. While inherent measurement uncertainties exist, a realistic challenge would require post-audit revisions uncovering a higher unlogged peak or sensor recalibration, though such adjustments are rare after full-day reporting. Final certified data expected soon from the station's daily summary.
