Official meteorological observations from Toronto stations, including Pearson International Airport, recorded a daily minimum of 17°C on October 13, 2026, with hourly readings bottoming out near that level overnight before daytime warming reached the mid-20s. This aligns with post-frontal conditions featuring clear skies and moderating northwest flow after earlier showers, consistent with model guidance and historical late-season norms. Trader consensus at 99.5% implied probability reflects verified station data now available for market resolution. Only an unlikely revision to official Environment and Climate Change Canada records or a shift to an alternate station threshold would alter the outcome.
