Official observations from Environment and Climate Change Canada at Toronto Pearson International Airport confirm the highest temperature on April 26, 2026, reached 14°C, driving trader consensus to 100% implied probability for that outcome as the market nears resolution. This aligns with pre-event forecasts from Canadian meteorological models predicting mild daytime highs near 12–15°C under partly sunny skies, persistent light winds, and seasonal influences from a neutral-to-weak La Niña pattern limiting significant warming. Historical April averages at Pearson hover around 11–12°C, making 14°C a plausible peak without anomalous heat. Realistic challenges, though improbable post-observation, include rare data revisions from quality control audits, but current records show no such discrepancies. Traders await final market resolution based on these authoritative measurements.
