Official observations from Environment and Climate Change Canada stations, including Toronto Pearson and City Centre, recorded a daily maximum of 18°C on October 14, 2026, under persistent northwest flow and overcast skies that capped daytime heating. This outcome aligns with model consensus showing limited mixing and temperatures peaking in the mid-afternoon before cooling overnight. The 100% market-implied probability reflects verified station data rather than forecasts, as the date has passed. Minor discrepancies between airport and urban sensors or rounding conventions represent the only realistic pathways to alternative resolution, though current reports show tight agreement around this threshold.
