Official Environment Canada observations at Toronto Pearson International Airport confirm the highest temperature on April 29, 2026, peaked at 13°C, anchoring trader consensus at a near-certain 100% implied probability for this outcome. A cold front drove northerly winds gusting to 30-40 km/h, persistent cloud cover, and scattered light rain or drizzle, suppressing solar heating and convective warming despite early morning readings near 13°C; subsequent hourly data showed temperatures dropping to 7-8°C amid cool air mass advection from the north. This matched pre-event forecast model guidance projecting daytime highs of 11-13°C. Scenarios challenging this include rare post-finalization data revisions by the resolution source (Wunderground's Pearson station history) or unverified station discrepancies, though official records stabilize within 24-48 hours.
