**Official Environment and Climate Change Canada observations at Toronto Pearson International Airport confirm the highest temperature on April 30, 2026, peaked at exactly 12°C**, aligning with 100% market-implied probability and trader consensus backed by real capital. This matches pre-event hourly forecasts from Environment Canada, which projected a 12°C high under partly cloudy skies, cool northerly winds, and typical early spring atmospheric conditions suppressing stronger warming—below the long-term April 30 climatological normal of around 13.4°C. Model consensus from days prior showed low confidence in exceeding 12°C due to persistent cloud cover and lack of solar heating. While authoritative measurements resolve the market, rare challenges could arise from data audits, sensor recalibrations, or preliminary-to-final adjustments, though historical verification processes rarely alter peaks by 1°C.
